Hi All,
I have a M1009 with an arctic heating kit that includes two heaters under the hood, one for the coolant/oil (I believe), and one for the batteries and cab. The coolant/oil heater was disconnected when I got it, but the battery/cab heater worked fine. The fuel pump on the driver side does not seem to be working. When I engage the heater from the control unit in the cab, I can hear the heater on the passenger side click, but no sound from the pump. When the system worked, I could hear the pump working before the heater fired. The pump feed both of the heaters, and in the process of replacing the pump the second time, I blocked the outlet for the coolant/oil heater with a brass fitting. I don't think this should effect anything, but I want to give all information for readers.
I'm thinking this is an electrical issue and that the pump is not getting power. Is there a systematic way to test/troubleshoot this? I have rudimentary knowledge of using a multi meter, otherwise, I don't know anything about electricity. I can test for voltage, amperage. and resistance. Does anyone here know where to test the system and what to look for.
Any advice is appreciated. Thanks in advance.
