MEP 1040 won’t start

These new style gen sets do not like low batteries. So I would still get the one old battery load tested.

Note the word LOAD test, not Voltage test. Too many folks overlook that fact that a bad battery can quite often show a surface charge of around 12.4V, making if appear to be fully charged, but throw a load at it and there's absolutely nothing there to back it up!
If ever in doubt, get yourself a cheap $20 battery load tester. It will take the guess work out of battery diagnosis.

I have a load tester and will test the “good” battery when I get home from a short trip I am on for today. Thank for the info.

Go slow and make sure you don't have other problems.

When you get known good batteries in there see if it will bump over with the dead crank switch.

Before doing that see if you can spin the engine over by hand.

Definitely good ideas. I will do this for sure. Does the dead crank switch work if the DCS is faulty?

From the schematics it looks like it would.

I seem to remember being told that the S10 would crank the unit, without the DCS being active.

Hey thank you to everyone for helping getting this gen set running. I did pick up new batteries but I also found that the slave connection was wired backwards. While this did not cause a problems likely unless you tried to jump it with that connection. Anyways we are up and running. Looks like it needs a thermostat so I am gonna look for that as it seems to be stuck in the closed position. Engine gets hot but is not letting coolant circulate through the radiator.

Did you bleed the air out of the system with the bleed valve? Better get to reading the TM lots of good info in there

Yes I did do that as per the TM but no change in coolant flow.

One of the GREAT light shows of my life working with "Army Stuff", was watching some contractors repeatedly try and stick a jumper cable into a slave recpt. wired up backwards. And the fact that they continued to try, after the first screech and blinding flash of light, was unbelievable. Better then watching Boob Tube!
