I knew there was a good reason I have a one wire alternator.

Subject: [oletrucks] Alternator Wire Swap
Something that happened to me that I'd like to share.
When I was working on my engine, I had removed the alternator wires after
marking down where the wires were originally terminated.
When I was done my work on the engine, I put the wires back according to my
diagram.
Before and after the engine work, I was experiencing a battery drain of
approximately 350 mA and I didn't know why.
I asked the previous owner if he noticed a drain on the battery when sitting
for long periods of time. Yes he did.
I had disconnected anything that would be a draw on the battery and even
pulled the fuses one at a time until I had nothing left for load.
Everything I tested pointed to the alternator every time.
After talking to the mechanic at my work, he figured that maybe the two
small wires that are close together on the alternator were swapped.
I tried that, and found that the current draw was reduced from 350 mA to
about 3 mA. This condition must have been present for quite some period of
time.
Now I can leave the truck sit for as much as 1 1/2 weeks (the longest I've
let it sit) without any ill effects.
