About a month ago my battery light came on dimly while driving. I kept using the vehicle as normal and noticed that the battery was not charging as well. Finally last night I had to get a jumpstart. After checking and replacing the voltage regulator I got a jumpstart. The car started and ran for about 5 seconds then died. I repeated this several times and each time the same thing. I had my buddy watch the voltmeter at the battery terminals. 12 volts at the battery, jumpstart, voltmeter shows 6 volts at the battery terminals, then the engine dies and voltage jumps back up to 12.

Assuming the alternator is bad will that really cause the engines to stall? The fuel pump is OE/mechanical so I never imagined this issue could exist. Is there anything else to check?


I also added a ground strap to the engine but it does not seem to have any effect with this issue.
