Went to an MG club picnic last night, about 40 minutes south of home. On the way down, in a hard rain, noticed the generator light in my 66B glowing just barely and wipers and turn signals slow.
Uh oh.
When we got there, I asked some of the guys to help me check it out. Tried to start the car, but it wouldn't. Went to check the battery connections, and here's what I found:
Hitch hiker photos
This wasn't what was wrong with the car, but it sure was amusing... (This is my Ofoto site. Sorry, but you'll have to sign on to see the pictures. It's free, but annoying. Someday I'll get my own site, so I can post photos here that show up...)
Anyway, after I took care of this problem, one of my friends gave me a fresh battery, and we left before we needed headlights to get home.
With the new battery in, it started right up, but apparently was not getting a charge from the generator. (This is a 66B, positive ground.) We checked it with a voltmeter. Read 12v off fresh battery, but voltage dropped sharply when I switched the lights on, and didn't go up from 12v at all when revved.
Generator light started glowing softly again after about 10 minutes on the road, but we made it home OK at dusk with no lights.
I'm suspecting the voltage regulator. Connections all seem to be good, and I know the brushes in the generator are OK.
Uh oh.
