IH 574 Diesel Fuel Gauge

cking526 · Aug 29, 2009

Installed a new sending unit yesterday only to find out that gauge was still not working. Then I found I broken wire. I spliced temporarily and gauge was working. Then when I wired permanently gauge was dead. I can not get it going again. I even ran a direct wire. Any ideas? It wouldn't need an inline fuse would it? The wire at the gauge looked like it had a fuse at one time.

Hi, I believe the fuel guage sender unit provides a ground to the fuel guage and the other connector on the fuel guage will go to a 12V source that will come from the ignition switch there probably is a fuse on the 12V side.
The wiring for the fuel guage sender unit probably goes thru the connector at the rear of the seat under the platform. The ground point is usually a wire that has a lug that is on one of the bolts at the back of the seat that holds the platform on. The connector can be troublesome as well as the ground lug not making good connection due to rust and dirt.
