Alternator Overcharging?

I am electrically challanged,so I need some help! Some years ago I put a rebuilt 63 AMP alternator on my 69. It's externally regulated. I took the car on Powertour East (remember those?) and it kept pushing the battery caps right off the battery! Every time I opened the hood the caps would be laying somewhere.I finally duct-taped the caps on and finished the tour.Of course,the battery was junk by that time.I haven't used the car since then,but have had it running on a few occasions and noticed it doing the same thing-pushing the battery caps right off.I also noticed the factory volt gage showing a lot more voltage then ever before.I'm ready to start driving the car again but need to get this squared away.I could go back to a 37 AMP alt but I thought if I can make this one work,I'd be ahead of the game.Any ideas?

Re: Alternator Overcharging?

Try swapping voltage regulator ... You can get a Wells electronic for less that $15 ... I am assuming you are running with external regulator ... If you are running any accessories, the 63 Amp is preferable to the 37A ...

Re: Alternator Overcharging?

the wells # is vr715, autozone carries them.

Have you done any voltage checks?
When I first put my car back togther, my rad support was not grounding (too much fresh paint!), this caused the system to charge at 18 volts! That woulda popped some caps off the battery for sure. Doubt it's your problem, I some some real freak shows with front lighting, too.

At the top of the electrical forum is an "electrical basics" sticky. I (with some help) put it together to help people overcome being "electrically challenged" maybe give it a read?

Re: Alternator Overcharging?

Just dump the alternator and put a self regulating in...
No messing around, destorying more batteries, and costs for the next 15 yrs or so.

My Spelling is not incorrect...it is creative

Re: Alternator Overcharging?

Thanks,guys,I'll try the Wells regulator. I usually try not "Get in the Zone" but maybe if I have a part number in hand I'll get the correct part! JimM-I did start to read the electronics sticky last night,I'll give it another look.Thanks for the effort you've put into it.
