MEP003 Help

[BBELL]

I have a mep003 that is putting out 160 volts and can't control it with the rheostat. I got the old one to work shortly so i figured it had a bad rheostat. I installed a new one today and no luck still no control. Thanks for any help!

It is probably the voltage regulator, I am fairly sure the voltage regulators on the MEP-002 and MEP-003 are designed to fail at full voltage, there is a trouble shooting and repair section in the tech manuals.

Thanks for the help so much for simple fix! I will have to read up. Is there a common problem on the regulater that might stand out?

Check out TM5-6115-585-34. pretty good step-by-step trouble shooting. Start on page 2-11 step 18 for "HIGH GENERATOR OUTPUT VOLTAGE (NO LOAD)."

Yes, the common problem with the regulator is a failed output transistor that suffers from a collector-emitter short circuit. It's a $1 part to replace, and really simple if you've got a friend that's into electronics and repair.

Thanks for the lead! I will have to find someone that can fix it.

looks like the others have beat me to it....you got a bad Voltage Regulator. Easy fix and probably cheap. Full schematics and component values in the TM. Good luck, and keep us posted

Finally got the voltage regulater back and in. I am ready for hurricane season now. It works perfect! Thanks for everyones help!

Did you repair it or replace it? Where did you buy parts?

 

[BBELL]

I had it repaired at a local shop. I can find out all there Info and post it. They also found someone to rewind my 005 voltage regulater main transformer (Said it was to difficult for them). They seem to really know there stuff and have alot of connections.
