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.

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.

Having trouble with high coolant temp light and shutting down, coolant level is good, temp light comes on quickly and shuts off, not even showing temp change on gauge, other times comes on after a minute or two, sometimes temp gauge goes high as well? 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!

Hello, I have a question on the way the remote start kits work for my MEP802 generator. The kit works fine but it seems that if the generator doesn’t auto start the first crank cycle due to cold weather the controller doesn’t try starting a second or third time. How does the remote start controller PCB work? Should it try 3 times to start and then lock out? I don’t see this sequence of operation covered in the manual.
