    Mep003 voltage drop after 7500w

    Unlike other generators the AC Voltage Regulator in the 002, 003 does not directly drive the exciter. It does it indirectly via the CVT and other components. Here is an excellent video on how the voltage regulation system works. YouTube Video You may want to swap the AC VRs between the two...

    MEP-803a Measuring current on L1 in 120/240V

    The %Load meter doesn't actually display the current at the L3 lug in 120/240 mode. The %Load meter is actually displaying the current provided by one of the 3 pairs of windings in the gen head. In 120/240 mode the %Load will display the total load applied to L1 and L3 combined, not just L3. The...

I don't have a way of marking up just 1 page and swapping it into other PDFs without a fancy PDF editor. If it's just a few notes like I did in my test TM in say two TM's per...

    Mep003 Putting out 300 VAC and stalling

    Also visually check the VR board for burned components. I've repaired a number of the VR's and besides the three transistors failing I've also found burned out resistors. Obvious charring. The diodes are prone to moisture creeping into them causing them to open up internally. If the diodes...

    Cleaning/disassembling the K1 AC Circuit Interrupter

    @Browning1 If you aren't getting any fault lights when the contactor opens on its own under a light load, then I'd suspect an issue in the latching circuit that is supposed to keep the contactor closed. The diagram below shows the electrical path of the latching circuit. K20-9 gets 24 volts...
