My 2008 5ECD won't crank when I place the master switch (on the ADC2100) to run and I'm out of troubleshooting ideas. The battery is supplying good voltage to the starter solenoid and the generator cranks fine when the solenoid is jumped. The ADC2100 seems to be functioning properly, it sends the start command to the Relay Interface Board, the run, crank and flash LEDs illuminate and the power arrives at the solenoid start terminal but the solenoid does not function. I replaced the solenoid yesterday with a new Kohler replacement part, no change. If I jump the start terminal directly to the battery terminal the solenoid functions and cranks the generator just as briskly as jumping directly from batt to the starter terminal. I realize this is providing a little more voltage to the start terminal than it normally receives from it's circuit so...I suppose it's possible that the new solenoid is bad also. What am I missing? Solenoids aren't that complicated. Any suggestions before I take it back off? If you're unfamiliar the 5ECD uses a remote, insulated base 89-850187 solenoid, Kohler PN GM45936. Thanks in advance for your help!
