It has gotten worse over time. There was a time when it was smooth regardless of load. At first it started surging when there was no load and ever so slightly. No it's a substantial surge at any load and the exhaust cover bounces at times.

I could have explained that better. Yes, you are correct. When it's under load, If I move it left about half way to cutoff, it will stop surging and will then maintain a constant RPM under load.

Hello all! I have an MEP-803A that has developed a substantial surge. When it's started for the first time of the day, it runs fine until it gets warm. As long as I apply load before it gets warm, it will maintain just fine, but if it gets to warm prior to a load being applied it starts to...

I went through every relay and tested for correct functionality when 24V added along with continuity, resistance, etc. All relays tested the same and were functional. I went through every wire on K20 and jiggled and re-torqued all the screws. There were no loose screws. Long story short, I...

This one is a stumper. I have unplugged the fault panel and there is no change to the situation. When I turn to start, I can watch K20 close, but as soon as I release the switch off of 'Start' and it returns to Run, I can watch K20 opens again. If I hold on start to keep power running through...

Thank you for the advice. After disconnecting the original wire, I went ahead and sent 24V directly to terminal 'X' from the starter and the gen is working fine. Switch S5 works as intended and illuminates GS7 light when put to 'Close' and the main lugs are powered. When I disconnect the jumper...

Sorry for the confusion....Yes you are correct on your assumption. With any 'new' or otherwise functional replacement of K20 relay and without doing anything, the CB1 pops within a few seconds of generator startup. The DS7, AC Circuit Interrupter light does not light up. K1 is not closing. In...

The replacement relays I'm referencing are brand new in sealed packages. Same manufacturer and part numbers. See attached PDF with photo. Here's where things start to not make sense..... I tested both the old and new relays IAW TM -24; 2-33.2 (See Attached PDF for photo). For some reason, both...

Started and check for voltage at K20 terminals 6 & 9. Terminal 9 has voltage of 26.7V and terminal 6 is showing -2V. I shut the unit down and swapped out K20 with a brand new relay. Within just a couple seconds of starting the unit back up, CB1 popped and the unit shut itself down. The old relay...

The contactor does not close while holding the switch. The contactor has been tested and is functional the 2V I stated was actually showing up as a negative 2V on my meter....? It remains unchanged when I hold the switch up.

Hello All! I have an 803A with roughly 2000 hours on it. It runs regularly. During use one day, it ceased to send power to the breaker panel it’s hooked up to. After investigation, I saw the green AC Interrupter light was off and would not come back on. The unit is not hooked to anything that...
