Just picked up an auction truck 2003 M1078A1 no start problem . Dash lights come on no crank . Anyone know a place to start bad solenoid ? Relay ? switch off somewhere ?
Jumping it off another military truck via Nato Slave .

I never really have put in the work to figure out why - but the 12v part of the system (low voltage issue) seems to be a problem. When I first got my M108x truck, it would sit for several days - then would not crank. I could jump it off my regular civilian 12v truck by attaching to the 12 volt side.
Ultimate solution to that particular problem was re-cabling the batteries. The jumpers between series and parallel connections were non-standard and too small. Bought new cable ends, then crimped and soldered them to the factory cable. Also purchased new battery terminals - not the cheap low voltage marine grade lugs.
On a NEW TO YOU truck, I think
Suprman and
NDT both make good points.
Fresh hot batteries are always a good thing!
