Mep 002a voltage

Read my last post please. You're on the wrong transformer. You're measuring "1C" and "2C" of CT1 when you need to be on "C1" and "C2" of CVT1.

Note that the diagram label "front" is away from you when you're looking in the enclosure. C1, X2, and C1 are nearest CT1.

Oh my God willtry again

I just went out to my MEP-003A and looked. You're on CT1. CVT1 is the one that's away from where you're sitting when you look at the pair. CT1 should have "CT1" molded into the housing facing you. That's the wrong one.

Put those wires back on and find C1 and C2 on CVT1. I found a diagram someone drew that shows the terminals. Locate screw terminals C1 and C2 and verify you have the correct terminals by finding the markings near them, molded into the plastic. Remove the wire from one of them and measure the resistance between those two screw terminals on the transformer. You may have to remove the wires from both of the terminals so you can see the "C1" and "C2" molded into the plastic, therefore indicating you have the correct ones.

OK, so the control winding of CVT1 looks good. Everything is pointing to the regulator board. You did say it's an intermittent problem, which means you might have just caught CVT1 when it was behaving. Therefore it's not a 100% certainty unless you swap it with the one in your other generator, but that's what it looks like.

1st off THANKS!! It is no longer intermittent producing 156-+ & 300 + consistent, not able to swap parts, suggestions to what I should replace 1st & supplier very helpful

Are you hoping to diagnose and repair your board, or are you looking for a new one?

New one, you’ve got a pretty good sense of my diagnostic abilities, even either well trained professionals in the OR guiding

I'm thinking just buy one of Triple Jim's redesigned regulators and be done with it!

Buy Triple Jim's board, best money I every spent. I've purchased a couple over the years for different units with VR problems. So if anyone needs an old board, that is not functioning, I'll let them go at a good price.

I appreciate the reviews guys. I'm glad to hear success stories. Bob's will be on the way to him in the morning.

Many thanks to all, look forward to getting my security blanket back up & running!!! To all be safe & well!

Wow the new Lakeland regulator board arrived last night!!! BRAVO What a beauty, hopefully weather will hold, patience prevails, & can get it installed today & fire her up!
Thanks Jim & all who have helped to get me this far.
Be safe & well
Bob
