SOURCE: I have a 17kw generac generator that will run

I have the 18KW model and was told that most alarms relate to a low battery. Make sure the battery charger in the Transfer Switch is properly feeding the battery or hook up a mobil battery charger to the battery and see if the alarm goes away. Good Luck.

SOURCE: generac 20,000kW Standby generator doesn't start shows message STOP ALARM OVERCRANKED

Overcrank means that it tried to start and couldn't. It will go through 5 crank cycles and then stop with this alarm. Switch to off, hit enter to clear fault and then try to start in manual. Check to make sure you have fuel and pressure is 11 to 14 in WC.

Keep getting under voltage fault. I have cleared fault several time. generator will run for short period then fail.sometimes the fault is underspeed.

See if reducing the number of things connected to the generator will stop your problem. Disconnect or turn off some things that are not totally necessary.
To properly generate electricity, the engine is required to maintain an rpm within a specific range. If you load down the generator with too many things pulling power, the engine will not have enough HP to turn the generator within the set rpm range. It goes under-speed or under-voltage and you get a fault.
Going to the extreme, if you disconnect everything from the generator and it still fails, you have a generator problem

    Why doesn't it start?

    gen sets have to be run at set rpms so that the voltage and cycles are correct for the applications
    with the rpms as little as 100 rpms below requirement , the voltage will be down , causing a brown out which burns out electric motors and if the rpms are low the required cycles will also be off which affects electronic equipment
    service the gen set and find out why the rpms are not at the set level

    Generator alarm underspeed

    When you get the under speed alarm is the generator under load? Try manually starting the generator with no load and let it run for a while, if no alarm, then put it under your home load and measure current draw (maybe have an electrician check it) if the amp draw and in rush caused by compressors, pumps motors etc are within the generator rating, check your fuel pressure, on average 8-11 WC Nat gas. Pressure may test well under no load but drop starving the engine of fuel unde rload. Underspeed is just that engine cannot make RPM/Frequency

    Generac Generator won't stay running

    It sounds like you are not producing any voltage. When you start your generator have a volt meter on the generator breaker to see if there is voltage present when the genset is running. Also, check you oil pressure switch, which is near the oil filter.

    Theft alarm problem

    Same problem here but with a Toyota Sienna '99. It took $600 in diagnostic work but the problem was a low voltage electrical short in a switch that was part of the passenger door lock. Specialty shop found it by placing voltage testing equipment on 4 to 6 wires at a time that ran into the cars computer. They recorded any voltage spikes over all these wires 24hrs/day over 3 days to find the bad switch. Snipping the wire to that switch meant the alarm would always go off if the locked car was opened with a key in the passenger door lock but we we're ok with it. Car was about 5yrs. old when this ocurred but we never had another problem of any kind with it for another 4 years. Thanks, Dan
