Hey all, I bought a Hisun 550 back in June of 2019. After 6 weeks of ownership, this machine took to sputtering when started and under power. I checked everything I could think of before I took it back to place of purchase....(rural king), since it had a one year warranty. They kept it almost two months stating they were waiting to get info from Hisun to rectify the issue (supposedly faulty drivers seat belt). I was told by the tech that they replace seat belt harness and cured the problem. It did! Ran just fine again for almost a year and now the very same issue has returned. After doing a little investigating on my own, I noticed that rural king did not replace the seat belt harness at all. The wires to seat belt connector was cut and spliced and taped back together. Now I’m not real sure what the real problem is as that tech is no longer with company and can’t seem to locate the past work order for my machine. Hisun customer service is non existent . I’m on my own and begging for help. Im mechanically inclined but if this is an electricical issue, I’m screwed! No warranty left. Any help would be gratefully appreciated.
I have a HiSun Vector E1 (as they're called here in the UK) and have been running it for about a year now. It has an annoying problem that my dealer has not yet managed to fix.
On a full charge, at the start of the day, it works fine - albeit not the quickest machine in the world. I use it on my hill farm here in Scotland, and it has to climb a bit, although nothing that would leave you out of breath walking. The E1 copes with these hills no problem, until it's done about four or five miles, then it starts to struggle noticeably, and throws of the 4C53 error on the dashboard readout - low voltage according to the manual. Sometimes it does this even while the charge level indicator is showing a full charge.
It's been back to the dealers twice now, and they've replaced all of the batteries. I've emailed the UK distributor for HiSun in the hope of an answer, but as yet have had no response. My dealer is trying to get an answer from them too, before taking the machine back to try and fix it again. Meantime I can only use it for a short while each day.
I'm no electrician, so has anyone on here any idea what might be going on? It seems that it is struggling to draw enough power from the battery pack going uphill, leading to a voltage drop that trips the error code. But if that's the case, then the E1 is surely not fit for purpose.

Our Hisun is not making any power. Once you start to climb RPM's it almost sounds like the timing is out, it sputters and farts and doesn't want to climb RPM's at all. It starts fine though.
I checked and set the valves, they were a bit tight but not bad. The spark plug is very black. The exhaust valves are a real nightmare to get to fyi.
On the last service the dealer put the wrong plug in, so I'm switching that back to stock as soon as we get one. I'm also thinking the air filter should be checked/cleaned.
Any other things to check?
Good morning everyone, appreciate any help on this. I picked up a 2013 Hisun 800 for a project. Previous owner had fried a lot of the electrical with a bunch of aftermarket audio equipment, so I have been replacing all of the wiring to give it a fresh start. I'm 95% there with a couple of plugs I can't figure out where they need to be routed and the reason for me reaching out for help here.
1. A female 2-port white plug that comes off the end of the main harness, close to the side where the terminal hook ups tap into the battery. It has a Blue/black-stripe wire and a White/blue-stripe wire. (Pictures: https://ibb.co/m9PRDqX and
https://ibb.co/9pHZsFj). I'm assuming it is another single offset fuse or module like the other pieces around it but can't find anything on what it might be or that wire color combination in the manual/wiring diagrams...anyone know what this guy goes to?
2. On the crank position sensor (torque sensor), the wires that I have coming off of that are a green wire and blue/light-gray-stripe wire (https://ibb.co/FmJLJfs)...any idea on where this guy is suppose to plug in to?
Again, thanks for any help you can provide!
