Weird charging symptoms...

mb523 · 09-30-2007, 07:11 PM

Battery died today in the middle of a parade. Was going very slow and starting and stopping a lot, my guess was it wasn't charging very well at the slow speed. Got it home, charged it, and tested the charging system... jacked rear up and ran engine. Seemed OK, overcharging a little (spiked to 15V a few times. Took it for a drive with meter on terminals and got the WEIRDEST readings. Driving normally yielded a pretty normal charging voltage (aprox. 14V), but when I slowed down to a crawl (speed at parade), I got a -1.000 reading on my multimeter display. It also flashed a whole bunch of numbers between the negative #. I have NO IDEA what is wrong here! Stopped, it was normal battery voltage. Reverse also caused the meter to read negative.

What is going on here!?! I am planning on changing the OLD SCHOOL mechanical voltage regulator with a solid state 80's model regulator. I found some instructions on another forum on how to do it. I will check with author for permission to copy them here, they are very good directions.

ANY light on this problem would be GREAT!! Thanks!

I purchased a new VR from Ron and installed it as per directions I found online. The install went smoothly and now my charging system works like it is supposed to! Here are some pics of the install, because I like pics.

New VR.

Old VR.

Connections made up.

Blurry... inside of old VR. It smelled like burnt electronics.

Installed and ready to go!!

Thanks again Ron!!

No, he tested his and it was dead so I bought a new one through Ron!

You must have been doing some pretty serious calculations on that thing with that TI-83 Plus.

C++ programming my friend!! Was doing a time calculating program and had to validate all the outputs to make sure they were all correct!

So basically, yes.
