Fermont MEP-803A 10kW
Purchased for home usage, drained all old fuel topped off with new. When in aux prime, the aux pump works for aux but when moved into start position for the main tank pump does not have voltage to power pump. First I thought it was the pump, but once I unplugged and put meter on it, it was verified no voltage but the strange part it does when in aux?. could it be the sender in the tank closing the circuit? or am i going about this incorrect??
