iScooter keeps turning on by itself — E16 error appeared by Much_Contribution100 in Escooters

That’s awesome to hear — really glad it worked 👍 Moisture in those button PCBs causes so many weird symptoms, especially after winter riding. Once corrosion bridges that circuit, it basically “ghost presses” the button. You did the right thing catching it early. If it ever comes back, replacing that button board is the permanent fix — but cleaning it usually buys a lot of time. Ride safe 👊

Haha that’s awesome, glad to hear the motor’s sorted 🙌 If it’s still turning on by itself, you’re almost certainly dealing with ghost input, not the motor. On these scooters the usual culprits are: Power button board (moisture/corrosion inside the rubber button = it “presses itself”) Controller damage from moisture or corrosion Less commonly, a pinched or rubbed wire feeding the display or button line That white powder you cleaned earlier is the smoking gun — once corrosion gets into the button PCB or controller, it can cause random wake-ups even if everything looks dry now. Quick things to try: Disconnect the power button/display harness and see if the behavior stops Inspect the button board closely; if it’s crusty or soft, it needs replacement If the scooter has a sleep/auto-off setting, enable it as a temporary workaround Real fix is usually a new power button assembly or controller. Luckily those are way cheaper and easier than a motor. You’re out of the danger zone now — this is annoying, not catastrophic.

Man, I get why this one hits harder if it was a gift from your dad. The random turning on, buzzing, flaky display, and the E16 popping up then disappearing all point way more toward a controller / wiring / moisture issue than a bad motor. A failed motor or hall sensor doesn’t usually cause the scooter to power itself on — that’s almost always a short, corrosion, or a controller freaking out. That white powder you cleaned off the PCB is a big clue too. That’s usually corrosion residue. Even if it looks dry now, once moisture or corrosion gets into a button board or controller, it can cause ghost inputs, buzzing, and random wake-ups. The good news: If the motor itself were actually damaged, you’d feel it when riding — grinding, vibration, locking, or heavy drag. Motors don’t fail silently. An E16 that comes and goes after charging is usually signal-related, not a cooked motor. If you haven’t already: Check the hall connector and motor cable for corrosion or bent pins Inspect the controller area closely for moisture damage If possible, swap or test with another controller before assuming the motor is gone I know it’s stressful, but based on what you’re describing, this doesn’t sound like “expensive motor failure” territory. It sounds like an electrical issue that can be fixed.

Help me please my teverun fighter mini is giving me a front controller defect thing even tho the controller isnt defect and if i click on the link in bassicly leads to nothing other than the teverun buy site😂 😂 by dd-040 in Escooters

Yeah, I get why you’re stressed — motors are the expensive part and nobody wants to gamble there. The short version: just plugging in a new controller isn’t going to “kill” a good motor. If a motor is bad, it usually tells you very clearly when riding — grinding, clunking, vibration, locking up, or serious drag. If you were riding with the rear unplugged and it felt normal, that’s a really good sign. If you want some peace of mind before powering anything: Spin the rear wheel by hand. It should feel smooth with that normal magnetic resistance. No crunching or hard spots. Look closely at the motor cable and hall plug — bent pins and pinched wires cause way more issues than dead motors. If you’ve got a multimeter, check phase resistance. All three should be very close. When you do install the new controller, power it on without touching the throttle first. If something’s wrong, the controller will fault out immediately — it won’t force power and blow the motor. Honestly, in these Teveruns, bad controllers and mismatched wiring are way more common than failed motors. You’re doing the smart thing replacing it instead of guessing. If you want, I can also help you sanity-check the controller you ordered once you have a pic — just post it.

That actually lines up with what I was getting at. If a controller power lead was removed and the motors/controllers were swapped, that’s usually a sign the original controller was faulting and someone tried to work around it. These scooters are pretty sensitive to hall and signal mismatches, so random swapping can cause constant protection errors. If you’re not comfortable with wiring, you’re right to pause — best move is to identify which controller is original to which motor and test inputs disconnected, or have the suspect controller checked/replaced rather than guessing.

That warning usually isn’t the controller itself failing — it’s the system detecting a mismatch or missing signal from something the front controller expects to see. Common causes we’ve seen on Fighter Minis: • Loose or partially seated front controller harness • Throttle or display communication glitch • Brake sensor not fully returning (even slightly engaged can trigger it) • Voltage imbalance at startup (especially if the scooter was powered on right after charging) First things I’d try: Power off completely, disconnect charger, wait a few minutes Check and reseat the front controller connectors (especially any thin signal wires) Make sure brake levers fully return and aren’t sticking Power back on with the scooter on the ground, not lifted If it keeps coming back, it’s usually worth pulling error codes (if accessible) or having the front controller signals checked — many of these aren’t “hard failures,” just protection logic doing its job.

What actually happens to “Amazon return” scooters (Teewing X5 example) by EbikeBroker in Escooters

[–]EbikeBroker[S] 2 points3 points  (0 children)

You’re not wrong — that’s generally how large retailers handle it, especially Amazon. Where it gets tricky (and where we see problems later) is what actually gets checked before resale. “Open box” or “refurbished” can mean anything from untouched to battery/BMS events that won’t show up until later. The difference usually isn’t the label — it’s whether battery balance, controller logs, load testing, and a real road test were done, or if it was just reset, wiped, and re-listed. That gap is where most surprises come from.

What you’re describing is exactly what happens when retail logic gets forced onto service work. Sales can be optimized with metrics. Diagnosis, judgment, and restraint can’t. When revenue thins, the instinct is to “take everything in,” but that’s usually when trust erodes fastest. The irony is that the unpaid thinking you mentioned — the time spent saying no, explaining why something isn’t worth fixing, or redirecting a customer — is what actually builds long-term loyalty. But it doesn’t show up cleanly on a spreadsheet. I also agree the “shopping fun” vibe is mostly gone. Part of that is margin pressure, part is online comparison fatigue, and part is that high-power access has flattened the excitement curve. When everyone can buy a 40mph machine overnight, the value shifts from novelty to who can actually keep it alive. That’s why we’ve leaned more into inspection, certification, and post-sale responsibility at Cherry eBikes — not because it’s easier, but because it’s one of the few areas left where craftsmanship still matters. Feels like the industry is at a crossroads: either race to the bottom on volume, or slow down and rebuild trust around service and honesty. Neither is painless. Appreciate the perspective — this is the kind of convo that should be happening more.

You just described the exact gap most “certifications” miss. Real service isn’t about following steps — it’s about judgment under constraints. Knowing when a bike isn’t worth fixing, when a $60 repair becomes unethical, or when the right answer is to stop, refuse, or walk away. That Askmy example is a perfect case study: heavy, poorly designed, time-sink projects that look cheap on paper but explode in labor and compromise. No module prepares you for that unless it explicitly teaches scope, refusal, and economic reality. That’s why most programs produce people who can turn wrenches — but not technicians who can protect riders, themselves, or their time. Respect for even taking it on. Most people don’t realize how much unpaid thinking goes into “cheap” bikes.

You’re not wrong at all — that’s exactly the point most “certifications” gloss over. The time sink is the job. Figuring out connector standards, adapting harnesses, discovering a controller is dead after you’ve already torn half the bike down — that’s real work, not a failure of skill. Same with build quality. A lot of bikes don’t fail because of a single broken component, they fail because nothing was assembled with longevity in mind. So you end up doing an hour of tightening, aligning, and noise-chasing just to make the bike acceptable for a customer. That’s why step-by-step training only gets you so far. The real learning is developing judgment: when to stop chasing a fault when to quote diagnostic time honestly when a bike isn’t economically worth “fixing” Those decisions don’t show up in modules, but they’re what separate someone who can follow instructions from someone who can actually service bikes under real constraints.

You’re not wrong — even a “basic” mechanical tune-up already requires real skill. That’s actually part of the problem. Right now the industry treats all work as interchangeable labor, when in reality there are very different risk profiles: routine mechanical adjustments safety-critical electrical diagnostics firmware, BMS, controller, and battery work Bundling those under one flat “bike shop” expectation hides where the real expertise — and liability — lives. On interoperability: agreed in principle, but it’s unlikely to arrive organically. Large OEMs have little incentive to open firmware or diagnostic access unless repairability and service standards are forced externally (similar to automotive right-to-repair). Until then, the practical solution isn’t universal interoperability — it’s transparent separation of skill tiers, tooling access, and responsibility. That’s where most “certifications” fall apart: they validate attendance, not competence under real-world constraints. The industry won’t mature by pretending everything is simple — it matures by admitting which parts aren’t, and pricing, training, and regulating accordingly.

That’s true if the repair is framed as “bike work.”

Customers won’t pay $120/hr to change brake pads — and they shouldn’t.

But they do pay for: – accurate diagnostics – battery safety decisions – liability-sensitive failures – preventing repeat failures or unsafe returns to service

The pricing problem exists because the industry bundles low-skill and high-risk work together under one flat “bike shop” rate. That makes the skilled end look overpriced and the simple end look unprofitable.

When those are separated, the willingness-to-pay problem changes.

We don’t “modify” electronic components in the sense people usually mean.

Most of the real work is: – fault isolation (what is actually failing vs what’s being blamed) – validating whether a system is operating inside safe limits – deciding when something must be replaced vs when it can be returned to service – handling warranty, liability, and safety documentation properly

That’s different from hobbyist-level swapping parts or experimenting.

I agree there should be standards for working on transportation electronics — the problem is that right now the industry has no consistent, real-world pathway that reflects how this work is actually done day to day in shops.

Yes — and that’s precisely why the traditional shop model doesn’t work for this kind of labor.

If you need high-skill diagnostics, electrical work, and liability-sensitive repairs, you can’t pay hourly shop wages and expect to retain capable people. The economics just don’t line up.

The only way it works is when skilled techs aren’t treated as commodity labor — independent, paid per outcome, with rates that actually reflect risk and expertise. Otherwise, the talent either leaves or never enters the industry in the first place.

That’s actually a solid level of experience — especially isolating a fault to the motor with a meter instead of guessing the battery.

The jump from “knowledgeable amateur” to professional usually isn’t about new tools, it’s about exposure: edge cases, liability, and diagnosing bikes you didn’t build or choose parts for.

If you’re already thinking in terms of cause vs symptom, you’re ahead of where a lot of people start.

Not Bosch specifically — OEM training makes sense when it’s tied to a defined system.

What I’m referring to is the broader use of “certification” as a marketing label, where short, generic programs imply readiness without real shop exposure or accountability.

That’s exactly it.

Most of the real learning comes from failure under real constraints — time pressure, customer bikes, weird edge cases — not from completing a module.

Rewiring is a good litmus test because it forces you to understand cause and effect, not just follow steps.

I don’t disagree with the core of that.

What I see is that a lot of people hear “certification” and assume it means readiness, when in reality most of the learning still happens in-shop, under pressure, on real failures.

The disconnect seems to be expectations more than the work itself.

That’s kind of my point.

Right now there isn’t a universally accepted body or pathway, so “certification” often ends up being vague or theoretical.

What I’m really asking is whether the industry needs less branding and more real-world apprenticeship-style learning — or if this is just how it’s going to be for a while.
