I finally, tried the tilt which caused the volt meter to drop back down to 12. After adjusting the motor up or down, the gauge would drop to 12 and then work it's way back up to 15-15 volts.


Anytime a load is put on your power supply, there will be a voltage drop, especially something that pulls as much current as adjusting the tilt.

I would check to make sure none of your electronics would be affected by the slightly higher voltage. If not, just let the alternator do its thing.

If you put a volt meter on some of the outlets in your house, I doubt you would get an exact 120V anywhere. There are small fluctuations that do not make a huge difference.

Hammer could be right in that your meter could be bad, but I doubt it since you say the voltage returns to 12 after the motor is off.

PS I'm about to graduate in electrical engineering, so while I'm not expert, I feel I know a couple of things.

I agree with Bapple.

Although I'm not nearly an electrical engineer, I did stay at a Holiday Inn Express last night.

Yeah, I'm going to do this tomorrow (the volt meter is at the shop and I don't feel like getting it right now).

All of the electronics worked fine while out there (but I didn't have the GPS or a few other things with me)
I started to worry a little because it started to get into the warning "danger" zone on the volt meter...and I didn't want to get stranded in the middle of the bayou by myself.

Also worried that it could cost a pretty penny to fix if it's an alternator or some type of power regulator that needs replacing.


I'm no engineer, much less an electrical engineer...so I'm more or less up in the air about what could be the issue.

All I know about lectricity is: Don't pee on a lectric fence and cats do funny stuff when they get into letric fences.
