Hi, I'm a mechanic and am at a loss for a customer's 2021 UT400. This thing only got used for the end of the summer, only has 3.3 hours on it.
So far I've found:
No start - starter switch works, relay in relay/fuse box clicks. Solenoid is operating as it should, no signal to solenoid to start. Starts and runs when I hard-jump the solenoid.
No F or R lights on dash - N lights up, and goes off when shifted into either gear
No brake lights - tested switch, it works as it should
No turn signals
Parking brake light is on - switch is working correctly, doesn't change status
All connectors are secured, no wires look out of place. I have an incredible dislike for HiSun equipment. Every one I've dealt with has been full of gremlins. Has anyone else had any issues like this? Would this be something wrong with the dash? Or the relay/fuse box? or both? I don't want to contact Coleman and have them send a bunch of stuff that won't fix it, especially with how long electronic stuff takes to get these days. The last warranty I did for them was a go-kart that shelled the drive shaft bearings and it took 4 months for them to send us the parts.
Any help or knowledge would be much appreciated!
The middle two tires on 6x6 are spinning. the drive shaft from middle to rear is spinning and the shaft from middle to front is spinning. I have the entire thing jacked up. When I first start it both middle tires will spin and the front two will spin for about 10 seconds. the rear tires do nothing. I can spin the rears wheels both forward or backwards at same time or one forward and one backward and vise versa. Is this normal. Do I have a rear differential broke or is something not engaging the shaft to the gears in the back. Would somebody please tell me how all the drive system works together so I can find something to fix of replace.
Its maker has affectionately dubbed it Teslaris, for obvious reasons.
The Polaris RZR RS1 UTV has a one-liter, two-cylinder engine that from the factory has around 100 horsepower, making the 1,383-pound (627-kilogram) UTV very quick. But there’s always room for more power in one of these vehicles, and instead of fettling with its engine, one dune vehicle aficionado decided to swap in the rear drive motor out of a Tesla Model 3 / Model Y.
We don’t know how many of the battery modules the put in the vehicle, but it doesn’t appear to be much heavier than stock and it goes up sand dunes with remarkable ease. Depending on which version of Model 3 was the motor donor, the drive unit could have either 261 or 325 horsepower, as long as the battery pack can supply enough wattage and voltage.
Judging by how easily it flies up the steep sand dune, almost lifting the front wheels off the ground under harder acceleration, it’s safe to say it looks like a real hoot. The steep grade you see it tackling in the video uploaded by the electric UTV’s creator, Ron Cobbley, is located in the St. Anthony, Idaho sand dunes.
We found more videos on vehicle’s official Instagram account and aside from how interesting it is to see an electric powertrain in an application like this (and how it changes the vehicle), we also noticed that you really hear the tires on the sand more. Usually, this sound is drowned out by the engine.
The sound’s tone and pitch probably change with speed, giving the driver audible information to help him or her gauge their speed. You don’t really get this in a road-going EV driven on tarmac, which is why it’s trickier to drive an EV quickly - specifically because you have no way of knowing how fast you’re going just by ear.
2009 Hisun HS700 UTV ---- I thought the problem was electrical but I just found this in the oil filler tube.By Rick McGill
I thought the problem was electrical but I just found this in the oil filler tube. Does anyone recognize the part? I know I'll have to tear down the whole engine, and maybe I'll find the rest of it in there. Something beg enough to seize up the engine. That was the problem I was trying to diagnose.... 'Cause it's locked up.
Thanks in advance.
