I just ran power to the car, when I turn the key to on it blows the 10 amp gauge fuse I have determined it is the left hand gauge with the fuel temp etc. When I unplug this gauge it does not blow the fuse. I have checked all the wires with a multi meeter and they are ok. When I check the wires for power only one has power and one barly lights the probe the others have no pewer. Any ideas? What do I do next?
