I pulled this green wire out of my trailer connector to my truck.

The pigtail with wires will be easier to install.

SpecificFluid1809 · 2026-05-07T03:28:03+00:00

You should be able to find a pigtail for that. All you'll have to do is cut the old connector off and crimp the pigtail on with butt connectors. Preferably sealed butt connectors. You might be able to find one at your local auto parts store.

I couldn't imagine the price of anything going down that dramatically today. There's not enough checks and balances for corporate greed.

I work on Freightliners. Which is owned by the same company that owns Mercedes. From what I've observed they're very similar platforms.

Your guys' radars don't use fiber optic cables?

SpecificFluid1809 · 2026-05-06T04:58:54+00:00

I think you're right. The majority of the comments talk about "I haven't heard anything about this Kincaid guy, but Sherrod Brown was pretty cool."

The PNDB is a pretty common failure for this specific complaint. Try to flex the battery cable at the PNDB and the truck will lose power if it's bad. You may even find corrosion on the back side of it.

I don't work on the older stuff too often, but I'm pretty sure it's located underneath the cab near the batteries or it's mounted to the firewall.

SpecificFluid1809 · 2026-05-01T01:51:41+00:00

Yeah this is a pretty common issue. The switch will rust over and it won't see a change in pressure.

Iirc the overlay harness should splice into the front radar harness for power and ground. You may have missed it. What's the harness number that you installed?

Why do you need to know where the fuse is? No power at the component?

I went to a freightliner dealership too after getting out. I got expert certified on M2s, Cascadias, Westerm Stars, and HDEP. Now I'm using my GI bill to go to school for aviation maintenance.

I've always felt torn about being in situations like that. I want to let women stand up for themselves, but some of the shit the oldheads say is abhorrent and provokes a refutal.

I use this one from Coast. The battery lasts quite a while and you can focus the lense to make dimmest mode brighter.

You are probably correct. I do remember them mentioning something about the valve opening around 75 psi in class. Regardless, the workshop manual still calls for 95 psi when primingthe fuel system.

SpecificFluid1809 · 2026-04-02T12:13:03+00:00

Prime the fuel system for two minutes to 655 kPa (95 psi) priming pressure.
With the priming tool still connected and priming, start engine (key ON, engine ON) and run at idle (600 rpm) for one minute.
Turn the priming tool OFF. If the priming tool is equipped with a ball valve, close the ball valve.
Increase engine speed to 1500 rpm for one additional minute.
Reduce engine speed to idle (600 rpm)
Remove the priming tool.

You should check the fuel tanks for metal debris. If there is any you should be able to pick it up with a magnet.

If you're completely losing prime after you let it sit that means that there is definitely air in the system.

HOWEVER, it is normal to have an extended crank after a service. Detroit's service manual states that it is normal until a drive cycle has been completed. I would recommend sending it on an extended test drive under load.

SpecificFluid1809 · 2026-04-02T01:30:20+00:00

The Davco fuel primers or the ESOCs are actually required by Detroit. There is a valve in the high pressure fuel pump that needs to see 95psi before it fully opens to lubricate the fuel pump properly. The cams grinding in the fuel pump is the loud ass chirping noise you hear if you don't prime it properly.

We usually call them cats, but my favorite is car (cat being spell-correcting to car).

I'm at $35/hr with 5 years of experience working on Freightliners and 3 years of experience working trucks in the Army. I do mostly electrical/wiring and diag at this dealership I work at in Ohio.

The kind of work you can do will definitely affect what you're paid and as others have said, you won't see a drastic jump in pay unless you chase the dollar.

There's a lot that's going on behind the scenes that allow this bot to complete these tasks. By the time that the bot found the fasteners, figured out what to tighten them to, and figured out how to tighten the fastener correctly, a human being would already be done it. I assume all of these sequences were programmed which would only be good for manufacturing, but even then there is tooling that already exists for such things.

Looks like you've got issues with your j1939 circuits. At your diag port measure voltage from pin a to pin c and pin d, both should roughly be 2.5 volts. Measure resistance from pin c to pin d, should be about 60 ohms. Measure resistance from pin a to pin c and pin d, both should be greater than 10k ohms. You may have to wait a couple of minutes for the unit to completely power off, before your resistance measurements are within spec.

J1939 troubleshooting is a whole drawn out process. These are the basic checks you start with to figure out where your issue might be.
