I connected my fuel pump to the wiring harness and turned on the ignition. The fuse in the relay board blew. I checked for a short and followed it back to the pump itself. The positive pole of the pump has a resistance of 2.5ohms accross the positive and negative poles of the pump. The positive pole also has continuity with the case. However, when connected to the 12v battery, the pump runs. Is there an internal resistor blown? If the windings were shorted, the pump should not run. Suggestions?
What is the normal operating resistance across the pump?
Thanks,
L. McC
