Drain on Genset Battery

Drain on Genset Battery
Update...I'm checking to see if my new battery was DOA. I put a different
charger on it and when I came back it indicated a bad battery. (and battery
charges was at 10volts). ALSO I don't see any spark when I remove a cable and I
borrowed an amp meter, and if I used it correctly it was not showing any drain.

So now I removed the battery from the coach and have put it on the charger again
to see what happens. Could there be an intermittent drain that I didn't see?
That seems unlikely, but I don't know.

Thanks,
Alan

(genset is 8k, kohler, I think). I have never had an issue with the genset
battery draining, but I do now. I charged it for 12 hours yesterday, and this
morning, about 12 hours after charger cut off, it only had 10.3 amps (volt
meter), apparently not enough to turn the genset.

the meter not working before, so if it is not tied to the issue, it is a new
problem.

bringing along an extra car battery and putting it in a compartment to jump the
genset... but what a hassle.
