Genset MEP-025A
Well, finally I made a good deal (I think): got 6 units at $240.- ea.
They all are gov. rebuilt (at TEAD, ’80), still in their original boxes, never used after that, some even had the manual I was looking for! (TM 5-6115-323-14)
I could easily fix some minor details like fabricating a new teflon seat for one carb. that was flooding and replacing the rotten fuel hose on another one. Now they all run great. (Still wish I had the TM 5-2805-257-14 (A) which covers the 3 HP engine) Logsa…?
One of my intended uses was the alternative charging of large battery banks (400 Ah and up) in residential solar and wind powered systems. The only problem I see is that the current output (Amps) is not regulated, just limited by the circuit breaker to avoid an overload condition.
I.e., setting the voltage at 28V to charge a large battery which came down to 25V is not possible because the load current immediately rises to a level far beyond the allowed capability, almost killing the engine until the switch finally cuts open.
So it looks that I still have to figure out some kind of additional electronic to have it work for hours at max. 54 A, without correcting load voltage all the time. Or may be modifying the shunt to get a higher initial resistance value?
Any suggestions?
Mike: Once a year they have these US Navy – local navy exercises called UNITAS, usually some of the US ships stay in Montevideo for a short visit. The marines are always participating in those maneuvers. I used to have a good friend there, he was a DI. All I know is they could buy almost anything and take it back as “souvenir”.
If you had any connections that would be the cheapest way, by far!
