Hi All- Long time reader, first time posting. I have a 2016 Mule 4010 (model: KAF 620V). I am having an issue since overloading the payload a couple days ago (yes I'm a dummy). I live on a very hilly property and I was trying to move some large oak rounds for firewood splitting. I put WAY too much wood in the bed and when I started driving, it sputtered, kicked out of gear, and then cut out. I unloaded all the weight and started it again - appeared to be running fine when idling and/or driving on flat ground at slow speed. But when try to go fast or uphill, the RPM's rev high and it sounds like the motor is fine, but it has ZERO speed or power at all (literally creeps uphill at like 2-3 mph and won' go faster or take any weight), and has no power at all.
Other info: 3 weeks ago I did a belt replacement. So I was worried I perhaps screwed that up somehow. But I just opened the clutch housing to check and the belt and clutch appear to be working just fine.... sooo.....
Any ideas what I screwed up by overloading payload and immediately trying to drive uphill? Any tips would be greatly appreciated!
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?
Driving uphill - at the steepest section I lose power. The engine hesitates, stutters, I have to stop. The engine never dies, After waiting less than 30 seconds I am able to continue again.
Replaced carb, fuel pump, fuel filter. Problem seemed to be fixed but returned 4 hills later.
My LM700 worked perfectly fine two days ago but today it wouldn’t start, the battery is fully charged but when you turn the key over nothing?!?! The winch works fine but the headlights nor the low oil light will come on or illuminate when turning the key over halfway. Any help would be greatly appreciated! Thanks!
