Customer Question

I have a 20kw air cooled generac generator that has been very dependable until this fall. I changed the oil and installed a generac cold weather heat kit for oil filter and battery. I whent through the installation per generac's directions, but when I turned power back on and replaced the fuse the controller came on in the time of hour setting and won't respond to any input. It just run through the hours constantly. Could get any help from generac. Any ideas. Winter is coming all be it slow.

The first thing you need to do is to set the switch to the OFF position.

Pull the fuse out of the control panel.

Remove the negative cable from the battery.

Wait 5 minutes, and reconnect the negative battery cable.

Put the fuse back in.

If you still get no response from the controller, the controller has gone bad and will need to be replaced.
