Where to start looking....

68gtxman, Thanks for the quick replay! V @ battery is 13.5 (initial flash of 13.5 when probes contact posts), then immediately jumps down to 7.90 V! I though that was weird! I'm starting to think my Battery Tender is the culprit. Before this post,
I had cleaned up the grounding strap locations in the engine bay, and got very dim headlights, weak fuel pump and wipers. I am going to put it on a different battery charger, then re-test V again @ the battery. Will post results in a while!
Again thanks fro the response!
