Sam, I misinterpreted what you said. It's not a voltage regulator, it's called a "Slosh Module" and the fuel gauge is the only one hooked up to it.
I'm pretty sure the Ford trucks were using the slosh module. What it does is add a delay in how soon the fuel gauge reacts to the sender in the fuel tank. It's easy to check if you can get to the fuel tank.
Since the gauge goes to "Full" when resistance goes up, all you have to do is disconnect the plug at the fuel tank and turn the key to "Run". If the gauge goes all the way to "Full" and beyond, the slosh module and the fuel gauge circuit are working correctly. |
