Hello,
95 VP 5.0FL SX Cobra
I am putting a new bilge pump in because the old one did not turn on with the float (but would run in the manual mode). I am putting in a RuleMate automatic pump. There are 3 wires from the pump; 1 brown, 1 brown with white line, and one black wire (ground). The brown/white wire is the automatic and the other brown one is for the manual pump switch on the dash.
Three wires come from the wiring harness; 2 all brown, 1 black. One brown wire has 13 volts only with the switch on and the other measures 13 volts with or without the switch on...but drops to 2.5 volts when attached to the brown/white wire on the pump.
After attaching the wires it will work when the manual switch is turned on but does not go on when the float is pushed up.
The old pump was doing the same thing...so I don't think it is a problem with the pumps. Seems like there is insufficient voltage on the "automatic" wire when attached to the pump.
Any ideas?
thanks
