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!

Thanks. I've completely disassembled the keyswitch. It is a simple 3 post unit, and all contacts are working.

 

The newest issue is now that the F and R lights are working, and P-brake indicator turns off when they are on, but when you use the turn signal, no signal lights, but the P, F, and R will blink out with the turn signal. I'm going to go through connections under the seat again, maybe something came loose. It is starting to act more like a  grounding issue, but I can't find any chassis grounds on this thing. So frustrating.

Solved the problem. One of the connector insulators had slipped back and touched the frame, blowing the F2 fuse in the relay box. When I tested the fuses, all fuses tested good. I decided to go back in and pull all the fuses and re-check them. Found F2 was blown. The first check, I just checked across the fuse as it sat in the box. Of course, with the contact grounding out against the frame, it was showing the fuse was making continuity. So, I inadvertently found the issue and fixed it by undoing all the wire ties, basically. Now to button everything up properly so it doesn't happen again. I really don't like the cable management on these things (or any "chinese" units, for that matter). At least I got it figured out.

 

Thanks again for the manual.

Thanks for your hard work and determination to find the problem. My  problem is that when the temperature dips under 50 degrees, my Coleman 550 acts like the battery is dead and no electrical activity at all. The battery is at full charge. It only has 15 hours on it and the same thing happened last winter. Above 50 degrees, starts every time.  Very frustrating needless to say. Question is--- Could a short like that be affected by temperature?

      American Landmaster TW450 Won't Start!!
      By malenurse13
      We just bought a used 2017 American Landmaster TW450. No hour meter that I can find, so not sure exactly how much it has been used. 
      The first 2 days we had it, the starter was a little sketchy, but it started after 2-3 tries. Sometimes when turning the key, we would hear a loud metal "clink" sound. Like the starter made contact, but didn't have enough power to turn. 
      THIS MORNING... Turning the key, we hear a single click sound. That's it. Even with a new battery, the starter is still doing the same thing. Both batteries (old and new) were reading 12.8 volts on volt meter. So I'm wondering what else could be going on? Any ideas on what to look for would be greatly appreciated...
      Thank you!

      trying to finish assembly "new" 2021 Coleman ut 400
      By buckrub
      Hey guys! Newbie here. I'm an old man who's better with plowing a mule (4-legged kind) than these newfangled beasts. I, and a friend of mine, just bought new Coleman sxs and are having to finish the assembly. I've been reading on this site and I'm falling on the mercy of you experts. The only way I'm an expert is that an "ex" is a has been, and a spurt is a drip under pressure. LOL First off, the 2 buggies have no ignition switches. They seem to mount on the dash, not the opening in the steering wheel shaft cover, so we ordered new ones that are supposed to fit. They are 8 inches long, and have a 4-wired white plugin which is slightly rectangled when looking at the end of the plug. The trouble is there's nothing to plug into. There is a three-wire grey plug close enough to reach the four-wire plug, but of course, they are not compatible. 
      Secondly, the blinker, light, ect. unit on steering wheel just spins around when touched. I see no way in heaven or earth to secure it. I've looked at a diagram on the Powersports site, but can't detect how it mounted. Fellows I'd be so grateful for any help with this. Me and my mule will even plow your garden for free, for your help. LOL

      The UT400 definitive grease point thread
      By aefron88
      I've seen a number of requests for the location of all the grease points on these machines, and there is no definitive list in the manual. This covers the UT400, but other Coleman/Hisun models should be similar.
      Tools:
      First to grease your machine you need a grease gun and some NLGI#2 grease. You will find it helpful to buy a needle attachment as pictured here, due to poor clearance on some of the U-joints. The rest of the zerks use the standard attachment.
       
      Technique:
      Wipe any dirt/grease off the zerk before greasing to prevent pushing gunk inside and causing excess wear.
      Push the grease gun on the zerk at a straight angle and give it a few pumps. You will hear an oozing noise or sea grease coming out from the outside of the greased area when you've put enough grease in, a few pumps should be plenty.
      If it's just oozing around the zerk you either don't have a good seat with the gun, or the zerk may be rusted and the check ball frozen. Try seating it again and regrease.
      Wipe up any excess grease when youre done to prevent making a mess.
      Greasepoints:



      Rear A-Arms are greasable with the wheels on from the rear, I took the picture with the wheel off for easier visibility

       
      That's it. All other Hisuns should be substantially similar.

      Coleman 2022 UT 400 radiator thermo switch replacement question
      By moonrover
      Mine is overheated/burned/melt at connection with its wire connector, parts are ordered to replace both them.  This seems to be a common issue, and some of you already replaced it. I right now just connect the wires, so the fan runs  all the time whenever the initiation is on, but it's better let fan runs as needed with a working temperature sensor/switch. 
      Question: Does some coolant come out by removing the switch/sensor from radiator?  Or, is the threaded hole all the way inside radiator?   If the answer is yes,  I want to drain or extract  some coolant to make its level below the sensor before replacing it, so I don't make a mess with coolant spilled out 
      Thank you.
