COMPUTER/GEM SYSTEM

Ford Ranger

I have a 1995 Ford Ranger that looks a little rough but still runs well enough for my oldest boy to cut his teeth on. The only thing ever needed is a starter replacement about 2 years ago and a clutch replacement that took place a few months ago. At any rate, it's a manual transmission, 140000 miles, 4 cylinder that began to exhibit a rapid parasitic battery drain (before the clutch repair so it's not related to that). I checked all the extras that I had installed, phone system, lighting etc thinking that I had some wiring shorting. But now I've found that pulling fuse #25 labeled " Speedometer/GEM system" drops the battery draw (Engine off) from 234 ma to about 4. The high draw on that circuit remains constant even after a couple of hours, leading me to think that the electronics/computer are never shutting down. The ignition switch has been loose for a whie and now is very loose. I wonder if there is an issue in the switch that is " fooling" the system into not shutting down. Other than the " GEM" system however, all other systems act as they should when the switch is off.

Any suggestions? I'm trying to get this thing ready for drivers ed.

Thanks.

There is either a short in the speedometer wire or the hazards
