Hi guys,
This is my first post, so go easy on me...please.
I've got a MEP-806a here in Papua New Guinea. Great machine, and we use it daily as backup power for a church/school campus. We have done the manual change on the plate so that it will provide 220volts to match our local power. Great option! (She's a gas-guzzler, but otherwise a good machine.)
Here's my problem: I keep replacing the voltage regulator almost annually the last 3 years. Really perplexing.
It is giving me signs of the voltage regulator about to go bad again, and I'm seeing the signs and have just ordered a new one off eBay.
I've taken a video but not sure how to attach it.
The voltage just creeps up on its own over time...so after the generator runs about 50 hours, it has crept up from 220v to 250v. (Not quite linear progression, but all of the sudden I find we are up to 250v.) I thought someone was messing with it, so I put a mark on the potentiometer--nope the potentiometer is not moving, but voltage output is moving very slowly upward.
When I touch the potentiometer to bring the voltage back down to appropriate levels, the voltage jumps around, spiking up to 270v and dropping to about 200v before settling down again.
Anybody have any idea what might be going on?
Secondary question--I have a stack of old voltage regulators now. Instead of purchasing new ones ($700) every year, is there someone who knows how to bench test and solder what might be bad? Then I pay $100 for repairs and have a stack of standby regulators instead of messing with new ones every year.
Thanks in advance. Remember...be nice.
