hey folks, 1995 trooper 6cyl 5speed here, having the same problems as many of you. been having slow/jumpy starts for months and finally my dash controls quit working, fans won't turn on, and battery/brake warning lights stay on. i was told initially that it was some dash control unit that had gone bad (which, of course, isn't manufactured anymore) but after i told them to check the alternator (thanks to this forum) they let me know that it had gone bad. so it's being replaced now and hopefully will solve the problems. I'll let you all know, but im guessing thats the issue for many of the problems here

does anyone know how to fix the leak that causes alternators to fail in my 1994 trooper? i have gone through about six alternators that get burned up by a leak..my mechanic does not know where the leak is coming from..anyone know? is it transmission? oil? steering? what happens is a potentially dangerous situation where i lose all power while driving..last time it happened, i was merging into four lanes of highway traffic when i had a complete electrical shut down due to the leak onto the alternator..should i go to a transmission shop? any ideas please!

Check your power steering hoses. The power steering hose (low pressure side) is above the Alternator. I rebuilt my alternator... original unit, around 235k miles... I might add and had them increase the amp output. It was a Nippon Alternator I believe. Rebuilds are what they are... I haven't done this, but it may be possible to build a shield around the alternator to keep potential drips off of it in the future. Keep me posted!

Have you solved your problem? I am having the exact same problem and my mechanic can't figure it out. He has cleaned every sensor, checked connections and has hit a wall with the problem. I really like my Trooper, but I can't use my air conditioner and I live in Louisiana. Not a good combination. Thanks for any information you may have.

Actually I did find the problem with mine!!! The alternator was testing fine but I replaced it and the battery and my problems dissappeared!!!! I think something was wrong with it even though it tested fine. I did the work myself to save the money. Let me know if that works for you too.

We did have the leak fixed...I think it was oil or transmission fluid...it was easy to fix and so far so good although I still drive with one eye on the battery gage to make sure my new alternator is charging...if anyone else is having electrical problems similar to this I urge you to find the source of the leak because an alternator that continues to receive a leak will fail which could cause the vehicle to stop running...as a reminder, we narrowly missed a catastrophic event on a four land highway when the trooper shut down because the battery dies because the alternator failed because of the continual oil leak dripping on the alternator.

Hello guys. Simple & wierd question: does having low transmission fluid on a 95 3.2L trooper has anything to do with it not charging properly?
 
My battery gauge just went "south" and the trooper almost died, the tranny signal kept blinking, so I bought some fluid and even though it's not properly charging, i was able to get home
 
Any ideas?

i have not experienced the problem with the low transmission fluid, however, as a follow up to my previous posts regarding electric failure...the leak came back and fried another alternator, this time replaced the cam shaft seal and am told leak fixed this time...however, i just picked up my car after having new starter (oil on the armature) and the engine still is having trouble turning over..so we are testing out the battery and will run a computer diagnostic for the electrical system
