Jerking in fwd and rev does not drive.

Hello. I’m new to the forum and working on a Gem eLXD. Since I’m new I can’t post a new question yet and you seem knowledgeable about the codes. I’ve searched around and can’t seem to find mine anywhere. It’s 520518: 5. Best I can find is it may have to do with the main circuit or even the Trombetta solenoid. It seems to have an arc and slight melt but does click when the ignition is turned. Pushing the handbrake starts the “Whirrrr” but no forward or reverse and there is not physical microswitch for the accelerator. Any thoughts?

Could be the fiddler cable.

Need more information than that. What year?

Ohm out contactor coil.
If it clicks in, measure voltage across contacts. Before and after click.

Status of over current fault?
