I appreciate your help!
I am working on an Electric Vehicle that seems to have an Open in a ground circuit. The keyswitch is sensed to ground and seems to be opening intermittently when it is hot, and also when the motor controller goes into regeneration mode. Thus, we could be getting an induction "pulse" when we go from full power to full regen. This could be a swing of over 1200 amps DC.
I'm trying to see if noise on the ground circuit could be causing an issue, or if we have an actual open. I have a 2 probe Oscilloscope and I don't understand where to place my probes. Normally I would probe a signal line and reference to ground, but in this case that seems wrong.
Thank you for your assistance, I am a newbie to Scopes and mine is very cheap. I am an ME, but self taught in EE, so while I can do DC circuits pretty well, much of the EE world is unfamiliar so please be patient and give lots of details.
