I am not getting power to my fuel pump on a 85 GL1200. Where is the relay located that powers the pump? Suggestions on where elth I should be looking would be apprecated. pump works if I feed it 12V from the battery.
On the 1200 Interstate, the fuel pump is fed from the LT side of one of the coils, the right one when sat on the bike if my memory serves, but check ! this pulse is fed to the fuel pump relay which I think is sat between the coils under the front of the fake tank once the fake tank is off you can follow the wires.........
So the pump only operates every time that coil fires the spark plugs on two of the cylinders, in other words it dosn't have a constant live 12v.
to quickly check the pump works, follow the wire from the pump up to a connector behind the plastic drip tray for the gas tank filler, disconnect it and run a temp 12v supply to the pins (TAKING ALL APPROPRIATE PRECAUTIONS) the pump should run, you may have to start the engine or disconnect the carb supply line and place it into a container (if you do it this way you can measure the pump output) as the pump will stop when the carb bowls are full.
