Just experienced a power failure, and my home 8KW generator failed to start. I opened the case, cleared the ALARM - Overcrank message, and started via auto-start and it worked fine and shut down properly once power was restored. Weekly exercises seem fine also. Could cold weather here be the problem, or ???

Cold weather has a big effect on the 8kw, how cold is it. Was the weather damp that could have caused condensation? Overcrank could also be that it didn't crank long enough due to a bad starter contactor or bad starter. How old is the battery and are the terminals clean?

It would be helpful if you post the model and serial number of the generator for the techs here.  My 8kw 58820 had these symptoms and it was due to the valves being out of adjustment.  The service company who previously serviced my generator never adjusted the valves.  I adjusted them and it started up even in cold weather.

78Buckshot ... Thanks! yes, it’s been a combination of significant cold followed by dampness and melting subsequently, then freezing again ... I guess dampness is a good explanation, though when I intervened manually it cranked and started right away. I’m going to blame the hateful weather 🙂

thanks again!

 Have had a similar problem.  Battery found to be  "weak" only about 12 volts . Took it to the local auto shop and tested it for current and found to be done.New one installed and worked fine.   These batteries do not do a lot of work  and seem to have a shortened life span as result .As pointed out check for clean terminals ,loose connections on the starter motor and the starter solenoid or loose grounds . You stated that it was very cold, if not already think of installing a cold weather kit . Keeps the battery warm and heats the oil in the engine crankcase.  A bit of coin but worth it I think  Good luck

Not knowing the age of your unit it could have some issues with the ignition magneto, I have seen the damp weather cause the unit to fail due to grounding out the spark because of wet weather.

Thanks all! Though it's still quite damp, the temp has moved above freezing, and yesterday's exercise ran as usual .... So it seems it was the cold (and there was snow on top of the unit I cleaned off before manually starting previously). I'll have a routine servicing done to look suggestions made here. Thanks again!
