Re: Autometer Electric Speedo with Tremec T-56 Mag - issues with sende
Finally figured it out. The 2nd sender had a weak pin connector, I had nothing because the wire lost contact. I bought a 3rd from Ford for good measure just in case. Turns out there is a simple way to test these as per Bob Hanlon at Hanlon Motorsports. Put your OHM meter on the lowest setting on dc volts with +/- on the pin connectors and run a screwdriver(or something metal) across the pick up. If you are reading volts, you are good. Turns out my original sender was good which leads me to wiring and a continuity test. Turns out that the harness I bought must have had a broken wire from the factory or possibly pinched somewhere(which is nearly impossible because the harness is wrapped from the trans to just in side of the firewall). Luckily the harness had a yellow(ground) and purple(feed) wire in it running the course. The yellow wire passed the test so I grounded the one of the wires to the crossmember, and used the yellow ground wire as my feed wire - voila!
