Recently my electric water pump motor failed so I ordered a new center section and bolted it in and connected the wiring harness and the result was nada . No pump operation at all. I checked the harness from the engine compartment operated by a toggle switch (the pump is driven off a relay which is protected by a circuit breaker.) I have 12v going to the pump motor according to my meter. I checked continuity on the harness ground thinking there might be an issue there but I am good there. The new motor works because I powered it from a separate battery and it runs fine. So I took a new harness that was supplied with the new motor plugged it in to the motor harness put the hot lead on the battery positive and put the ground on the chassis basically duplicating the installed set up but I still get no operation. I know the setup I have from the dash works because in the original setup before the motor failed everything ran fine. Any help would be greatly appreciated!!!!!
