Yesterday my Trooper blew the fan circuit fuse. The book says it should be 25amp and it had a 20amp installed. If anyone can tell which wire under the hood is the fan wire I would really appreciate it. The instrument power has been intermittent at times and I suspect the two failures may be related.

As a side note: I did my first oil change - - boy was that fun!!! My car has the welded in skid pan so I had to cut a hole to allow the oil to drain without creating a mess. After trying several ways to make the hole I finally ended up cutting it with my die grinder with a 3" cutting wheel. To contain the oil I got a canning funnel (has high sides and a wide mouth) to direct the oil unto the catch pan.

I was real proud of myself - didn't spill a drop ---- until I kicked the dirty oil can. Oh well! Murphy lives at my house.

Any words of wisdom will be appreciated.

The fuse box is on the left side of the driver behind you. you can figure out which fuse is bad with a test light touching the end of the fuse with out pulling them out. there is metal exposed on each side of the fuse.

Hi Flatbed,

Thanks for the information. Just to keep everything exciting Joyner put the fuse box on my Trooper right behind the passenger seat. I did discover which fuse was blown but would like to know what color wire and were it's located in the instrument panel. I know is goes somewhere through the dash because it's tied in with the ignition switch when starting.

Reading the manual is a real challange.

Thanks again for the input. It is appreciated.

I doubt the wire goes to the panel, maybe to the relay box which is controlled by the computer. Open up http://www.utvboard.com/post-a88-.html and save your self a copy, it's an electrical wiring diagram.

For your oil, I suggest http://www.quickoildrainvalve.com/SearchResults.asp?Cat=210, take a look at Parts, Pieces, and Information for our Troopers, usually the 3rd topic under troopers and you should change the oil in your differentials also. At least open the fill plug and dip the oil to see what it looks like. Mine was silvery the first time I did mine. one bottle does both diffs.2093207660104110397PpxreP_th.jpg

It probably wasn't your fault that the dirty oil got spilled, it was one of those garage gremlins that hide tools, move parts and pushes things of your bench all the time.

Thank you Kinarfi,

I downloaded the schematic and now all I have to do is learn Chinese - ah sow!

Your idea is a good one. Putting a petcock on the oil drain should be quite safe from harm considering where it's buried.

I will definitely look into that.

Geez, you have a gremlin at your place too. He sure has a lot of relatives.

You folks on this board are awesome. It's good to be a part of it.

Enjoy your evening!

Every time my Trooper broke this winter I would wash it before taking it to my dealer. He got tired of replacing fuses from the frozen fan so he hooked me up with a breaker.

    • 2009 Joyner trooper starting problems

      I have a no cranking issue with my joyner. It has a chery 1100. It will click but nothing after that.  New battery. I tried banging in the starter while holding key in start(old car trick). Now the  starter solenoid won't even clunk. Just hear s click fron the relay now.  My assumption is the starter needs replacing.  Any ideas of other things to check? Does anyone have diese block diagrams?  Got no clue what fuse or relay goes to what

    • Trooper 1100 Turbo Kit?

      Hey guys, so i have built my own turbo kit in house and it works awesome! seeing these turbo kits for sale for 3 and 4k seemed a little steep for me.. i built my entire kit intercooled and all for less then half of that price so i am considering selling these kits.. if i could produce a complete bolt on kit that could be installed with simple hand tools in your garage strait for $1800 and intercooled for $2500 would any of you be inerested? i would like to post pics but not sure how to? i have also snorkled my trooper and not just the air filter but diff vents, the two chrome catch cans (crankcase vent and radiator vent) along with raising the ECM and fuse boxes to head level.. this as well could be sold as a kitfor very little cost. i can also do the work in-house if needed (install all of this for you) for only a couple of hundred... is this stuff you guys would be interested in? Turbo kits will be complete al the way down to an Autometer Vac/Boost guage, fuel controller etc.... i have seen a HUGE increse in power! if you have more questions you can call me at 713-824-8891 i'm in the Houston Texas area. Also Lenny would you mind calling me so i could pic your brain for a min? some questions about this site (how to post pics, stetting up my profile etc.) as well as a few other things. Thanks i love this forum and really look foward to helping in the future! and really like seeing extreme joyners on the trail!

    • Trooper computer programmer

      There is a company I ran across at the CES trade show this year. They make a programmer that should be able to program the Troopers computer. About $300. The Trooper s computer is a standard Bosch car computer. The only differance is that it is programed for the Trooper. The programmer will program most any car or truck so it should work. The company could probably help is finding which program the computer uses and assist finding out which computer pins to hook to. This programmer will program all aspects of the tuning including things like Pulse width tables, VE tables, Timing tables, prime pulse width, crank pulse width, after start pulse width, warmup pulse width, enrichment pulse widths, acceleration pulse widths. rev limit and more.

    • Wanted: Trooper Axle Parts

      I am interested in any old trooper axle parts you may have lying around. Please let me know if your want to sell them.  Backstory: Hey everyone. Last trip out to moab I climbed a wall on poison spyder Mesa while 2 rzr xp1000's and three can am x3 xrc's watched me and didn't dare try. After doing it once I pulled around to show them it wasn't a fluke. One on the can am x3 xrc drivers just looked at me and said "that's steep". On the second try I spread the bell on the left rear axle. I made the climb but now the inner cage slips inside making a loud popping noise as twisting the boot. I mainly just need the inner bell but I am interested in anything you have.
