Faulty starter

458 Amps sure looks like it but, at the end of the screen shot Amps go negative, did you zero the probe first, obviously won't change things much. I would put a wrench on the front of the Crankshaft to see if the engine rolled through with reasonable ease, "prior to getting EGG on my face again". Replaced one at customers request RO said so, and it was fried, but new starter wouldn't crank it either, AC compressor was locked tighter than a Bulls Butt. :(

Is it possible that then engine actually started, and this "Negative amperage" is actually current flowing back into the battery? Make sure to check the voltage reading aswell ;)

Yeah, like Preston said, did it start? I never gave that a thought. In looking again the Battery never recovered much over the initial start of the screen shot at the end either though.

Is this from the Dodge you found the bad ground on?

Gosh I gotta pay more attention to the date of the OP, It flagged "New" so naive me jumps right on.

I had the amp clamp around both the starter B+ and Alt together. Your seeing both current to start and Alt charging. Thanks... Mark

Next time can you just get to the point ? LOL. Thanks for the reply. Mark
