Yes. Depends on the tank and what the available fittings are on the tank. Do you have specs for the tank? Do you just need parts or do you need onsite labor. We do not do travel calls much, but can schedule with lead time.
I have a 20gal aux fuel tank that I need hooked to a met 802a. Can you do this, I live in Shrewsbury,Vermont. Davis Terrill just installed a remote start from you folks.I am disabled and the extra fuel capacity.
Check continuity of the fuel level switch. You might need a new sender.
I can start from the dead switch, but the main board shows low fuel and won’t start. It’s 100% fuel. Any suggestions?
Check the entire circuit for cooling temp. Ensure ground is good and connections good. You may need a new temp sensor.
802a, keeps tripping the high coolant temp shutoff, very shortly after startup, about 2- 3 minutes, coolant level is good.
this only started recently, prior did not have this problem?
CBs get tired with age. Certainly you can jump the leads and just try out a fresh CB to see if it too pops.
Is there a detailed schematic/electrical diagram available in pdf for the MEP 802A 60HZ? I had a mouse problem in the control box area where I need to replace chewed up and missing wiring. Would appreciate any help & guidance.

Not sure what you mean by “out of balance”. Is the unit shaking or are the electrical output legs not reading correctly? Make sure that the engine mounts are secure and make sure the dials on the control box are configure and set properly (e.g. if you want 120/240, make sure read-out settings are correct).
I have an MEP-803A, 9-6115-641-10, I purchased at military surplus auction. I do not know the history. It shows only 3 hrs on the hobs. Engine runs steady but overall unit is seriously out of balance. I am trying to determine the problem; engine or generator.
1) I am looking for an engine repair manual to see if flywheel or balance mechanism exists and installed incorrectly.
2) Alternatively, it might be a winding mis-wired.
Anybody seen this problem before?
Sorry but we have a unit thats the same model and we get the same problem. The CB1 keeps poping and we cant figure it out. Wanted to know if it was ever figured out.
Have you checked all the grounds? Is the unit grounded? Look for any loose wires in the control panel. Ensure that your batteries are configured properly for 24v. Is your master breaker off when you do this? Try to keep it off so no power goes to lugs when you try to reset the Circuit Breaker on the control panel.
I have an MEP802A 5KW generator that keeps tripping the CB1. Trying to find out what could be causing this. I push the CB1 in and turn the master switch on and about 3 secs later the CB1 pops back out. Your help would be greatly appreciated. Thanks. SSG Taylor.
