    Mep831a conversion time!!

    Mecc Alte should have included the J609B adaptor plate. Knuckleheads. Several have purchased from them and all received the plate. Wow the gen head price has gone up! It was about 350 shipped last time I bought one from them a 2-3 years ago. Be sure to connect the wire harness leads supplied...

    Is there a treaded barbed fitting for the oil drain on the mep802?

    A good hardware store should have the fitting you are looking for. Remove the plug and take it with you to the store so you get the right size.

    20kw Generator

    Actually, it is possible to convert a 15 kw 804 to single phase. It's just done a bit differently than a 12 wire gen head conversion. A few people have done it and can pull 15+ KW.

    Also the L3-L1 L3 position on the AM-VM switch will cause the %Load meter to register the TOTAL load on the generator, not just what's connected to the L3 lug. It registers the load on L1 & L3 combined.

    First MEP 803A, fix up help

    The overload was/is probably dirty contacts inside S8. When in 120/240 setting S8 connects R12 & R13 in parallel for an effective resistance of 3.75 ohms. The combination of R12 & R13 form the burden resistor across CT3. If S8's contacts for R13 paralleling aren't making contact the effective...

    The reason the readings are off is because the CT's and K8 are connected in parallel to the resistors in the circuit.

    MEP-831A Freq Converter (A8) rebuild - anybody have luck with repairing these?

    It seems the main control board is the culprit when that happens. Many people experience that same fault if they are in a high humidity environment. It's related moisture genning into the numerous un-sealed potentiometers on main control board on the engine side of the inverter. Some have had...

    First MEP 803A, fix up help

    To check R10, 11 & 12 you need to disconnect 1 of the wires from each resistor so that 1 terminal on each has no wires on it. I think you'll find they are OK. The original resistors are no longer made. The manufacturer does make a newer version that will mount up just the the originals. I'll...

    No relays in the panel lights circuit. Just S2. Diode mod involves tearing the VR apart and installing higher PRV diodes. A bit of a chore. Doing the MOV mod ought to protect the existing diodes.
