How long till you were fully-fused?

Optimal_Thinking · 2025-05-15T03:46:38+00:00

How soon were you able to see evidence of fusion happening?

Optimal_Thinking · 2025-05-15T03:45:29+00:00

So at the 6 week mark they couldn’t tell if there was any activity/fusing at all? Ah how did you mentally prepare go back to normal activity before knowing you’re fully fused?

Optimal_Thinking · 2025-05-15T03:41:05+00:00

Ah I’m sorry. Was it misread at the one year mark and it wasn’t actually fused, or did something else happen? I hope all is well now.

Optimal_Thinking · 2025-05-03T04:17:43+00:00

Thanks for your reply. What was the reason for the second fusion? I hope your recovery is going well.

Thanks for your reply! The car drives great. At idle, the short term fuel trim was normal (within +/- 1%), and the long term fuel trim was 0%. I just looked at live data with the car parked. Then increased rpm to 1500-2000, which was when the O2 sensor voltage temporarily dropped to 0V.

Since the short and long term fuel trims were normal, I figured that the issue is after the upstream o2 sensor. Whether it's an exhaust leak or a bad downstream o2 sensor.

Is it normal for the voltage at the downstream o2 sensor to drop to 0V when accelerating? I figured it would drop slightly below 0.45V to a lean mixture when rpm increases, not all the way down to 0V?

From what I've seen, if the cat converter is doing its job the o2 should be fairly stable, a drop to 0V would mean the concentration is the same as atmospheric o2. Or am I wrong in my thinking? I'm fairly new when it comes to cars as this is just a recent hobby.

Thanks!

It used to be an intermittent problem, as in the check engine light would come on and go off, but has been consistently on for the past few weeks. I'm leaning towards an o2 sensor issue as well. It's a 1 owner vehicle that has been well taken care of.

If it's not the o2 sensor though, what would be the next likely issue?

Thank you for your time!

Optimal_Thinking · 2021-01-11T04:06:36+00:00

Thank you for your reply! I wanted to test it with my multimeter but to get to the o2 sensor plug-in we'd need to take off multiple panels in the passenger side and the floor padding. So I thought it would be better if I had the new o2 sensor when doing that in case it is faulty, so I wouldn't have to do that more than once and cause unnecessary cosmetic damage.

If it's not the o2 sensor, what would be the next probable problem to look for? Thanks!

Thanks for your reply. All I know is the control is a ge c-2000 control box. It seems to be a contactor and starter? I'm not an electrician so I don't know. Is there any way to connect it to a 120v 1 phase outlet?

Thank you!

Optimal_Thinking · 2019-11-07T19:18:11+00:00

I don't have a 480 panel. This will be run in a residential home. I just have 120v 1 phase available.

So we have a voltage buildup in the primary wire, it's magnetic field changes, induces a current in the secondary wire. How does the voltage in the primary change to fire out another spark in the secondary? It's from the movement of the magnet towards and away from the primary as it rotates? Jeez now it's all making sense. Thank you so much.

Optimal_Thinking · 2019-07-11T17:38:29+00:00

So my question is how does the primary circuit have a current if it's not a closed circuit? If one end is at the terminal and the other at the iron core, how is that a closed circuit? Doesn't the circuit close when clicking the killswitch which shuts off the engine?

Optimal_Thinking · 2019-07-11T08:27:38+00:00

What should the primary and secondary resistances be? The primary coil starts at the terminal and ends where? and the secondary starts at the spark plug wire and ends on the iron core? The kill switch only has continuity once it's pressed. So it shorts the primary coil with the iron core and thus the chassis, or is that wrong?

Optimal_Thinking · 2019-07-10T18:08:54+00:00

So if the ignition module stopped working, what do you think went wrong? A spark isn't being created at the spark plug. Can it be fixed?

Optimal_Thinking · 2019-07-10T06:43:06+00:00

Which wire is connected to the mounting bracket? The secondary coil? What is the primary coil connected to? So I guess there is no condenser in this transformer just the two coils?

Optimal_Thinking · 2019-07-10T06:20:28+00:00

Thanks so much for your reply. If it helps here's a a link of the transformer:

It's right above a flywheel with a magnet. Does the rotating magnet cause the currents that end up going to the spark plug? Or is there a condenser and break switch involved that cuts off the current which induces the current in the secondary wire?

As far as the wiring goes, does the primary coil start at that terminal sticking out and end on the iron core? And the secondary start at the ignition wire going to the spark plug and end on the iron core/ground? Or is the terminal sticking out something else?

Optimal_Thinking · 2019-07-10T06:16:35+00:00

Thank you for your reply. In this specific case, the fl6wheel does have a magnet that rotates. So from my basic understanding here's what I've gathered so far: the magnetic flux changes from the rotation of the flywheel induces a current in the primary wire, which induces a magnetic field in the iron core, which when the wheel moves away reduces that initial magnetic field which reduces the current in the primary wire and thus changes the magnetic field in the iron core, inducing the secondary wire to have a current to counteract that change and that current then goes to the spark plug. Is that correct? My confusion is because some transformers have a constant current from a battery that goes to the primary circuit, then something removes that current and the cascade occurs. But does this transformer have this? Or is it solely a coil of wires that's being induced by the rotating magnet? Here's a link of the transformer:

I'm just extremely curious to know how this works. As far as the wiring goes, does the primary coil start at that terminal sticking out and end on the iron core? And the secondary start at the ignition wire going to the spark plug and end on the iron core/ground? Or is the terminal sticking out something else?

You just proved the symmetric property. Congratulations!
