You will need to get a wiring diagram to see everything powered off of the fuse that you pull out. You will need to start unplugging components until battery draw goes away.

There is a relay fuse under the hood. You want to check the relay fuse under the hood then check for a loose connector to the back of your dash. If these are good you'll need to take to someplace to have the ECM checked. This usually cost about $50.00

SOURCE: speedo,tacho,fuel gauge,temp gauge stopped working

Maybe, a wire came lose. Did you hit anything? Spill any water inside? Could be a short, considering they all went out. Did they all go out at once?

Since replacing the battery everything works fine except the speedo, Rev counter, fuel and temp gauges. All fuses in fuse box seems ok. ?

Hi Go to the Dealer and have them check it out. It maybe a simple and pushing a reset button. Or it could be something more complicated. Also check for code scan faults.#. Good luck

Hi, I have 1998 Ford F-150, 2wd automatic, V6. I seem to have a parasitic drain on the battery of about 4 amps, and I have traced it down to fuse #15 on the inside (the GEM fuse). Also, fuse #19 will drop...

GEM stands for General Electronic Module and controls a lot of non engine related things, such as power windows and locks. I had a 2000 ranger the other week I was working on with a bad one. To correctly test the GEM you need to hook up an amp meter to see the current draw. It takes the GEM about an hour to full power down. If your just sticking a test light on it, it may be miss leading you. Try hooking your test light up like you was testing and leave it like that for an hour without messing with the car, to see if the light is still lite. The best honest way to test is with an amp meter though. Should have .05 amps or less on it after an hour, anything more than that is a bad GEM.

The GEM in the ranger had to be programed by the dealer.

It sounds like something is drawing power with the key off. It could be the GEM module but I doubt it. There is a draw somewhere. Connect battery and pull fuses one at a time to see if curent drain stops. You will need an ampmeter in series with the battery and the postive cable. Expensive. Get one from pick n pull salvage yard real cheap.

    Battery has about 1/4 amp drain with everything off. Pulling fuse #25 (Speedometer and GEM system) brings the drain down to the normal 0.05 amp level. Problem is frequent but intermittant. Auto mechanics...

    You're right - nothing to do with the alternator. Question is, why would those accessories be active with the ignition switch OFF? Perhaps some problem with fuses being active that shouldn't be when the ignition is off.

    Well, it sounds like the loose cable goes back into the transmission -- that would be your speedometer cable.

    This cable would not cause electrical problems, but something pulled it from the transmission and may have, at the same time, pulled an electrical wire loose. I would check the transmission and surrounding area for loose wires.

    Generic Electronic module.

    The gem is behind the dash in the center, behind the radio. It controls whipers, anti theft, 4x4, cargo lamp, insterment cluster, plus a few other things. Hope this helps.
