I am new to the service industry and have a call from a customer with an Overcranking Alarm on a 14KW NG Air Cooled unit that will not turn over. I am thinking Fuel Supply or pressure and/or Battery Voltage. Is this a good place to start when I go out or should I pursue other avenues first. Thanks

I'd start there as well paying particular attention to the battery first. Fuel pressure usually doesn't change unless there is a faulty component, (fuel solenoid, etc), or the owner has added some other gas consuming device.

IF the above check out ok, don't go off into left field, break out the diagnostic manual and take a step at a time. You'll find it.

Of course you'll have the manual with you? ;)

i have also found if the fuel line has any bend or slight kink whatsoever....you would be suprised on what the wrong size fuel piping or a kink in the flex hose will cause.....i also had one where the customer had his drop leg at an angle.and it would always crank on 2nd or 3rd time.we straightened it out.BINGO
