The alternator and battery were working just fine before we dropped the motor. The PS pump was leaking a bit, so during cleanup I sprayed the alternator with carb claner to clean it. Maybe a week later the alternator was mounted to the block on the engine stand. The small wire which attached to the alternator was broken for about a year, and already repaired once. We spliced in a better connection, and also crimped on a new eyelet for the large wire.

I drove the car ~20 miles on the initial test drive. When I get back to the shop a friend notices the battery voltage is below 13, and the scanner says 12.4. We put a multimeter on the battery terminals and it appears the alternator isn't charging. I accidentally leave my wideband turned on and conencted to the cigarette lighter and the battery drains.

Notice the dead battery a couple of days later and my friend charges the battery. My friend did confirm all the grounds are attached. Park it and pick it up the same night and drive 10 miles home with the only issue being I lost my clutch pedal, presumably from the line resting on the header (fixed).

Took it for a test drive last night to work on the tuning. Drove it about 5 miles and pull off to make some changes in the tune. Dome light on, wideband plugged in, laptop not plugged in. A few minutes later I'm done, and the car won't start. The lights in the cabin dim while cranking, and eventually I get the fast clicking. Call a different friend and he comes to give me a jump. Car stalls once in the same parking lot, but restarted pretty easily. Follow my friend back to his house (which is on the way back to mine) and let it charge overnight.

He takes it to Autozone today to have the alternator & battery tested. He is told both are good, and the alternator is putting out 70A.

We plan on fighting with it this evening. Where do we go from here?
