      Hi there, I just acquired an MEP-803A from Camp Pendleton.
      All the fluids and the batteries had been removed.
      I have installed 2 new batteries, added coolant and oil. I have not yet added fuel.
      My problem is that when I hit the start switch, nothing happens.
      I have 25 volts at the batteries, and 25 volts at the MT-4 fusible link behind the panel.
      It will crank like a champ when I hit the dead start switch.
      Am I missing something? Is their a low fuel cut off switch?
      I get no power to any of the lights or gauges on the panel.
      Thank you
      Kevin

      I’m having trouble finding a circuit breaker fuse my MEP-802a. I’ve looked everywhere with no success in finding one. The number on the old fuse is: FO3 125V 30A. Is is also a ceramic fuse. Anybody have suggestions as to where to find these fuses, or what would be the replacement for it? Thanks for any help.

      My MEP802A will not shut down. Battle short is off. Nothing will make it stop. Even tried blocking air intake! What can I do?

      802a ran for a week or two aok, then died, had to replace start switch, replaced alternator. Unit now runs, but generator only puts out 24vac. Suspect glazed brushes. Anybody know how to put an external voltage on the generator output to break the glaze? Also, anybody ever replaced the generator brushes. The unit is trailered on a pu 797?

      I’m not sure if I’m doing this right. I just found this page and am not highly computer savvy.
      I just obtained an MEP-003A 10KW generator with a Lister-Petter engine. I’m having problems finding info on this unit. Like others, all the fluids were drained. So far I haven’t been able to figure out why I don’t seem to be getting fuel to the injectors but haven’t been able to find any info on that particular (water cooled) engine.
      Help is needed on the proper manual and that engine. I don’t seem to find am engine on Green Mountain’s list of Lister-Petter engines that looks like a likely suspect either.
      I’m pleading and begging for help!
      Thanks, Leonard
