What part failure would cause over charging?

[Omega Man]

I was looking at my volt meter this am and started wondering what is the most likely cause/failure if I noticed the meter was pegged to the right?

First suspect would have to be the regulator....assuming the gauge itself isn't flaky. Do you have a multimeter to check the voltage at the battery? That's where I would start....see if it actually IS overcharging first, then diagnose why.

I don't have this problem, just curious. I do have the multi meter if needed. Thanks Joel.

Yeah that would be a flaky regulator... not regulating the voltage properly... i.e. limiting it to under 14.5 volts...

Back when we had points in regulators they would overcharge when stuck. Come to think of it. I haven't read of overcharging in a long while. It's mostly been not enough charge.

My external alternator started putting out over 16 volts once. New internal regulator fixed it.

Overcharging can also be caused by a dead cell in a battery, loose or bad connection at the ground or a loose or dirty connection at the RR.

i know you don't have a problem with your alternator but the regulator is built in and it only takes about 40 minutes to change an alternator on a 1500 wing

remember i did a write up on the alternator going out on my 1500 wing, it happened about two weeks before the m&g at joes last year. all you would need is an alternator and new rubber cushions to do the job

My wing overcharged recently, turned out to be a bad connection at the regulator/rectifier. The voltage sense wire was not getting good connection. Cleaned the connections and added dielectric grease, and now she's better.
