I just purchased the machine, Parked it in my barn, I went out to use it yesterday, and I turn the key, and I dont even have a click of the starter. I replaced the battery, and still nothing... I have power at the key, and all lights lite up on the panel... but no fuel pump power, or power to the starter..
Power starts at the 40 amp breaker, to the main power relay and then to a 25 amp fuse and then to the fuel pump. At the key switch, check for power on pin A 622 wire in the starting position, power then goes to the starting relay. There are several connectors in there that the power goes through.
Thanks Tom, I will check that.. I am waiting on my repair manual with the schematic
While adding a case drain to my 420 a couple of years ago, I did not hear my fuel pump make any noise. The pump had failed but the machine ran fine. During the winter, I keep the fuel tank full for pushing snow. Check for 12 volts at the pump before making other checks. Do the easy things first.
