My son's minivan quit at my place on Monday. After I moved it into my garage, I checked the battery and had 0.7 volts. Previous to this, we had a battery charger on it for several hours. Last night I installed a new battery. When we tried to hook up the negative cable there was a very large and loud spark. I took an ohm meter and found that there was no resistance between the positive cable and the frame. There must be a direct short somewhere. My guess is that the positive cable to the starter must have worn the insulation off and shorted out. I think it could possibly be the starter and or solenoid, but that is not my first guess. Any other ideas?

Thanks, Roy
 
Agree, you are on the right track. If you are drawing that much juice you are likely chaffed on the positive bat cable or one of the power feeds that come off it.

You're on the right track here. I'd chase the positive cable all the way down to the starter first. If you don't find a problem, then take the cable off the starter and make sure it won't touch a ground by taping the bare terminal. Try to re-connect the battery and see if sparks again. If not, you've got an internal short in the starter.
Good Luck and God Bless
 
Oops, forgot to mention that you should not overlook the alternator, too. The big red wire on the back of the alternator also can cause a problem, as well as an internal short in the alternator.
 
What year is it? We have an 05 Uplander, (Chevy version) that did that. The dang computer is the regulator, or something to that effect, and that was our problem.
