On inspection, I see where battery acid has dribbled down onto my battery frame. This can happen for a couple of reasons:
1) sloshing around while driving (bumps, corners, drag racing, etc)
2) overcharging.
So, today, Christmas Eve, a bright, sunny day, I yanked out all my batteries, cleaned the corrosion off my steel battery rack, painted it with rustoleum and rubberizer, and reinstalled everything.
I fixed some of the always-present shock-hazards by placing split plastic tubing over all the battery terminals. Maybe I won't get the shit shocked out of me so often....
One thing I noticed....I still have 4 amps running through the motor even when the 72V circuit is open and the key is off, but only when the charger is on. I can't figure that one out. When the charger is unplugged and the circuit is open, no current.
Hmmm...I'll have to meditate on that one for awhile. I'm not sure if its a problem or not.
Merry Christmas, all my dedicated fans.
