My '95 XLT Special has an electronic fuel gauge. It worked last season, but doesn't work now. I have had an intermittent problem with my lights dimming at random, which seems to point to a faulty voltage regulator. But, I want to rule out a problem with the fuel gauge before I fix the voltage regulator. Does anybody have a wiring diagram of how the gauge is supposed to be hooked up and which terminals are for what? There are four terminals. The wires are brown, purple, yellow, and red. Does anybody know how to trouble-shoot these things? Would I cause any other problems by just unhooking it altogether?
