I have a 2019 hi sun 750 I parked it in my garage last fall and about a month later I went to ride it and I had no power but the battery shows good. I’ve taken the ignition switch out and cleaned it. I cleaned the battery terminals and replace the main relay all my fuses are good. I still show strong battery but get no power, can anyone help or have any ideas? I have yet to find any wires chewed up like from a mouse or anything all the wiring looks good.

DO NOT BUY ANY THING FROM HISUN Period! I had the axis 700 for 2 months when a rat or squirrel ate both wiring harnesses. (Main & ECM)Wanna know why? Because the manufacture of these things in their infinite wisdom use either, a soybean oil or a peanut oil to run the wires through the the wire loom. Hmmm i wonder why they would be inclined to eat the wires. So now I have $10K machine that I've only had for 2 months when all this happened and they will not warranty it at all. It is going to cost me $800 to $1000 to get this fixed. Here is a link to a video showing where we took our Hisun notice how many are there: https://photos.app.goo.gl/2FdniAoCyvTJMKae7 So counting mine, there are 16 of Hisun Axis on the lot that i took in for authorized dealer, with the exact same problem, plus other troubles that the mechanic explained to me. This particular place told me they are not going to work on them anymore. I will be posting this in as many places as possible to reach the masses. I hope its worth Hisun!

I just filed a claim with the WV Attorney Generals office against HiSun due to a 750 Axis crew blowing a Head Gasket 6 months after buying it and at 400 miles, it's now been unrideable for 6 months with no resolution except them sending a mobile repair tech to my house 4 times with no parts to repair it even though its under warranty. There is no authorized warranty repair facility near WV at all!

When mine broke on first day, i callded all three so called authorized repair shops..ALL three said they would not work on it unless I paid cash because Hisun and Massimo had stiffed them on multiple warrenty claims .Never paid one cent..Not even parts.. so color me skeptical on op getting everything fixed free

I hate to bring up an "old" thread, but did you ever get this solved? I have exactly the same issue with my 2021 Hisun 750 ATV. I attempted to start it a week ago, it turned over, then just shut off completely after abut 5 seconds...No power to the dash, winch, lights, turn signals, etc. will not turn over or start. Shorting the solenoid will only spin the starter motor, and not actually "start" the vehicle. I read somewhere else about a "dash ECU Fuse" causing a similar problem - mine tests fine with my multimeter.... I need my machine to work!

what happens when you jump the starter solenoid?

that is true.. We have a Jeep with the 4.0L six .. it leaked from every gasket.. BUT, not until 180,000 miles.. after I replaced pan, rear seal ,timing and valve covers, no more leaks.. Whereas HISUN leak on the boat from China . AND If a car leaks on day one, the Dealer will fix it.. Hisun will never fix anything. Their warranty is written on toilet paper so you can at least use it to wipe your butt

ahhh another satisfied HISUN customer... That will be the least of your troubles my friend.. HISUN is a snowball of catastrophic events
