Reassembly in progress. New sender. New wiring harness.
I found a post in the archives that outlined a way to check the fuel gauge. As I understood the instructions, connecting the input and sender wires should produce a full deflection and connecting the sender wire to ground should also produce a full deflection. I performed these tests in two places; 1) on the wires that connect to the sending unit, and 2) on the main wiring harness at the connector that plugs into the rear harness connector. Light green wire for 12 V to sender, and brown wire for sender to gauge. I connected a jumper to the pins for the green and brown wires and turned the key to ON: no reaction at the gauge. I connected the pin for the brown wire to ground: no reaction at the gauge. Same results at the wires connecting to the sender. The gauge points to a bit less than one-half full. The cluster is mounted on the steering column and the cluster ground wire (black w/ white stripe)is connected to the pin on the back of the cluster. Any glaring mistakes in my story?
I also connected a voltmeter between the green wire and ground, thinking that it should see 12V, but I got zero on the voltmeter. This makes me think I'm doing something wrong.
Comments appreciated.
