Onan Marquee Generator wont crank with plugs installed?

Hi, The starter on my Generator will crank and spin the engine freely with the plugs out. When I install the plugs it has good compression but will only spin the motor a 1/2 revolution or so then stop...

I keep coming back to "it takes more amps to turn over an engine with plugs in (because of compression) than one with plugs out." Back to voltage drop issue SOMEWHERE.


The problem has been solved. OP reported that it was a bad connection on one of the main battery cables; "It was a bad wire from solenoid to starter! "
