Problem restarting hot motor..

Stang_ROTY:

You shouldn't be getting any negative voltages. Are you holding the negative DMM wire on the battery? If not, then just reverse the leads.

At any rate, anything near 2 volts is way too much voltage between the negative post and ANY ground point. What guage wire are you using for your grounds? I suspect either the wire isn't beefy enough or your grounding points aren't making good contact. Seems the latter might be more likely based on what you saw after sanding. Check your crimps also.

Good luck,
