Fuel gauge.

[okiemark]

Everything is new. New tank. New sender. New wires. I checked to make sure the sender was grounded and that the tank was grounded. BUT! Here is something I did find. I went back and looked at the old dash panel and what did I find attached to the back of the speedometer? A little box that looks sorta like a relay. Two terminals. One wire went to the fuel gauge and jumped over to the temp gauge. When I get time I am going to get that little bugger off of there and hook a jumper from the battery to one terminal and check the voltage at the other side. This has to be the current regulator they are talking about, but so far I can't find one you can buy. You can tell this is originally factory wired in, but the wiring diagram in the owner's manual shows it but not in detail.
