2011 joyner r2 fuel pump fuse


Recommended Posts


I am having an issue with the fuel pump fuse blowing as soon as I turn the key on. The utv was running great and all of a sudden it blew the fuse and now wont run. The unit only has 250 miles on it. Any ideas on where to start? Im in western north carolina and cant find anyone to work on it. Thanks.

Sounds like a dead short to me. With 250 miles, I really don't think it could be much. I'd look underneath the thing, at the wiring. A lot of times sticks, or logs and stuff gets kicked up and can damage the wiring. Other than that, it could be the pump itself. Try un plugging the wire to the fuel pump, then turn it on, see if it still blows a fuse. If not, use a test light to see if you've got 12 volts at that plug. If there's 12v at the plug, then the pump is the problem.

I've got a mule, it's not for play. It's for work around the farm. But all off road vehicles can be subjected to a lot of abuse from underneath. I installed a large plate of 5/8 thick bed liner type plastic under the vulnerable areas on the mule. But I'm always pulling jammed sticks out from various places on the thing. And the mule seldom sees speeds over ten MPH. So that's the first thing that comes to mind with a relatively new off-road vehicle.

I'm not sure if I know what a Joyner is. I've seen the pictures posted by other members. They look like fun, kinda like a mini sand rail. If parts aren't available locally, looks like online is going to be the way to go. However, as popular as these things seem to be, there's got to be a dealer someplace within driving distance. I find the internet has way more choices for after market parts. As far as OEM parts, I like the web for those also, even car parts.

You mentioned not having someone local to service the unit. I'm very cautious about letting people work on my stuff. I've been burned too many times. Buy a service manual if you can, it's the best way to go.

Thanks Kenfain.....

Well, I had my neighbor take a look at the machine for me (I am out of state so I had him look). He said he disconnected the wiring from the fuel pump and turned the key and the fuse still blew. So, I am guessing the pump is ok, just as you suspected. Then he said he took out the relay and turned the key and again the fuse blew. So, are we right in assuming there is a dead short somewhere between the fuse and relay? Electical issues are such a pain.

Thanks for any insight.

At this point, a wiring diagram could be helpful. But at the least, you should see about finding what the wire color, and the routing of the fuel pump hot wire. On a small machine that doesn't have a lot of electrical circuits, you could probably just look and see where it goes.

Doing the easy stuff first, carefully inspect the wiring bundle you've identified as belonging to the fuel pump circuit. I usually start by careful inspection of the exposed underside. Sticks and logs get kicked up on the trail, sometimes damaging the wires. Often the culprit is still hanging there, so be vigilant, it could save some time. If this quick inspection doesn't turn up obvious cuts or contusions, you'll have to inspect the whole bundle from key to pump. Check wires for physical damage. Check plugs, switches, relay, and don't forget the ignition switch itself.

If that doesn't locate the problem it's time to use an electrical tester of some type. I'll use both a test light, and a meter, set to the ohms scale. That's for testing continuity.

Your problem does sound like a dead short caused by a break in the insulation. These are typically fairly easy to spot. Sometimes all you can see is an un natural bend in the wiring bundle. Closer inspection reveals the break. In most cases it'll take less time to find the problem, than it took me to type it. Keep us posted on any progress!

      Massimo 500 will only crank when I jump solenoid with screwdriver cranks right up and runs great. But won’t start with key doesn’t do anything when I turn the key. Only thing it does is power everything as in dash and fuel pump then have to jump solenoid to crank up and drive.

      OK, here's the mystery of the day. I was using the UTV the other day and the idiot light came on that said it was overheating. I immediately shut down and checked the coolant. No coolant! I refilled the overflow reservoir and the radiator and all was fine. 2 days later the light is on again. I rechecked the radiator and it was again empty? Bone dry? Now, here's the weird part, There is no coolant anywhere on the floor below the vehicle. I can't even see any on the frame. I have it up on the lift and am getting ready to start tearing into the bottom "skid plate" to see if the leak is in the hoses there. Any suggestions as to where to start? I have yet to begin and I am already baffled!

      Hopefully someone out there is a T-Boss 410 electrics expert or a Massimo mechanic is viewing this. I parked my 410 and it was working great. I came back a week later and attempted to crank it and nothing. Turned the key and no power. Figured it was a bad/low battery so I charged it. Still nothing. Attempted to jump start it and still nothing. Usually when I put the key in and turn it to the first position, the display comes on and I hear the ECU and other items boot. Now it is doing nothing. 
      I slowly went through the electrical system and found the main fuse attached to the starter relay, part 71602 (pic 1) blown. I figured replacing this fuse would fix my problem. It didn't. I then ordered a new starter relay thinking maybe that part had gone bad and caused the fuse to blow, but a new relay did not fix the problem. 
      I have found a work around for starting the machine. If I take one of the purple/black leads (pic 2) and insert one of them in the bottom right of the starter relay (pic 1 and 3) then the machine will get power even with the key in the off position.  I'm bypassing something but don't know what. I can use my right hand to hold the wire against the lower right of the starter relay, reach over and hold the brake with my foot, then take my left hand and turn the key and it will crank. As soon as I remove the wire from the relay the machine shuts down. I have even removed the power distributor box and it will still get power when I touch the wire to the relay. Of course this is not the way it should work but if I can't solve this problem somehow I may just have to rig a connector to the relay and bypass whatever is causing the electrical issue. Massimo has told me the purple/black wires on my model are not used.
      Any help in figuring what my problem may be or other items I can try?

      My T-Boss 410 died hard on a run up the driveway and wouldn't restart. Cranks over fine, 12v at coil, fuel in cylinder (from plug check), and wire from computer to coil buzzes out OK. Computer threw a P0351 ignition coil malfunction message. I pulled the coil, measured resistance across the primary, and it was about 0.8 or 0.9 ohms, nominal for most ignition coils. I measured the secondary resistance as well and got about 6.5K ohms, also nominal for most coils. I checked the plug wire resistance and it was about 5000 ohms, which seems OK. And really perplexing, my spark tester shows spark. I got to feel it too, when I held my fingers too close to the conductor. 💩! Have any of you folks run across this?

      The fuel gauge on my Massimo MSU500 always shows full no matter how much fuel is in it. Can anyone tell me why and how it can be fixed?
