Thanks, didgeridoo. The 12 V was not replaced when the defective propulsion pack was, so It is a suspect. The cleanup has been more than I envisioned as the insurance claim fell under homeowners so no “disposal” coverage for vehicles.. Draining fluids, separating melted rubber from melted aluminum. Two days of dirty work. Wear a respirator! Steel ready for recycling, melted stuff is in 9 grain bags for disposal. Only thing left to determine is disposal of hundreds of pounds of batteries. Just the lead plates and the tray they are welded to. Acid boiled off. A couple of dead fir trees. We are grateful that it happened outside, instead of in the barn at our remote farm. We do not live there. A barn full of other equipment not specifically insured. It’s a mess but passing. Thanks, mate.

I am suspicious of the 12V battery as well. All of the terminal posts melted to the point cables simply lifted off by hand. Battery cases melted into the trays so easier to cut the trays off. The acid is now part of the soil. The flames nearly set the fir trees on fire. A messy cleanup is underway. Sigh.

Good morning, Osney. Yes, the entire battery pack was replaced a year ago. I do not know about the heritage of the batteries themselves. I suspect there was a software update as well as reverse tone and some instrument panel indicators worked differently. We, too, stored our buggy in a barn stuffed with other equipment. It is on a farm property upon which we do not reside. Our first thought was “thank goodness this didn’t happen in the middle of the night. We would have lost everything”!

After a 7 month battle with Hisun to replace a defective battery pack (the unit was locked up in the service dealers yard the entire time) we got the vehicle back on our farm. We put about 100 miles on it (for a total ODO 425 miles) when this happened. While parked durning a lunch break. Hisun Motors has washed its’ hands of the situation and not remotely interested as to why or how a parked and shut down vehicle could burst into flames. Great idea, the E1. Poor execution. Abominable customer (and dealer) support. I wish you all the best of luck with yours.

In my case, Hisun replaced the entire battery pack. I also think there may have been a software update because the backup alarm sounds different and the 4x4 actuator works again. The dealer had our vehicle for five months.

i just this replied to another thread. We had the same issues, plus the 4x4 actuator failed. Resolved, but it took a load of effort to get Hisun to clean out the rats nest in Texas. Should be better now. Call Jamie Cheek, the guy who cleaned house. Good luck, and please post your results. Cheers. Hisun still keeps them close to the vest. GORJ posted a diagram above. It helped me a bit in troubleshooting. It did not reveal the problem. My issue was a failed battery pack that the onboard software did not detect. After a friendly call from my legal department, Hisun looked closer at the problem. Mr Sun sent in his troubleshooter, Jamie Cheek ( 214 542-3760) who fired several “engineers” at the Texas plant ( hard to believe the emails those guys sent to me and my dealer), and sent my dealer a fresh battery pack and software update. The machine has been flawless since. It was a five month ordeal. Ours is a 2019 model, but discovered to have been built in 2017. So the battery pack might have been dead before it got sold. The software upgrade was not specced, but we notice several subtle differences in the panel interface. All are big improvements. I hope your issues are resolved quickly. It really is a capable machine.

TapBoss, I will check that tomorrow. Thanks!

Thanks TapBoss. Si ilar to the cube on the back of the rocker switch? Maybe it is hidden in the bundle behind the dash panel.

I tried that today, Travis. Thought I was so clever…got into the harness behind the Forward/Reverse switch. Five wires. Removed each, one at a time. I can prevent engaging reverse or forward, but cannot silence the speaker. It looks like I need to remove the rollbar in order to get the dash board off. Don’t want that right now and so asked if anyone knew where the gd speaker is so I could take a short cut. Thanks to you I will go buy a pair of wire cutters. Thanks. Hisun is worse than horrible in providing schematics.

Does anyone know a simple way to silence the beep? I didn’t find it in the drive switch connector cluster and it looks like removing the dash board is difficult. Where is the speaker? Thanks

Gorj, thanks again for the diagrams. I finally got the 12 volt battery checked; fully charged. So, I think it may be solenoid or actuator problem. I'll get it on stands for wheel removal asap. Cheers.

I will do so on my next visit to the farm. Thank you for that information!

Unfortunately, my efforts to get a single specification page from HiSun has been refused. A service manual is totally out of reach at this point.

Charges overnight after each day of use. It has about 400 miles on it.

That would be wonderful, Gorj! Voltage on all the batteries is 6.3 to 6.4 volts, so why the thing So frequently goes into low voltage mode is a mystery.. We also love the E1. It ain’t stinky! And serves well on our rolling 40 acres. Another issue is that the four wheel drive quit engaging. Same “no help” from HiSun. We could trouble shoot if we had specs. I do appreciate you trying to get your dealer to help out, but understand that it might put him in a bind. Cheers

Thanks. I’ve been trying but COVID has destroyed his two man service shop. I have spoken to HiSun and they won’t release any specs so my electrical engineer son can try to run the problem down. We are pretty well stuck, literally, when the dreaded error code pops up on the panel.

Apparently, the solenoid connector from the instrument panel is vulnerable to moisture and dirt. The four wheel “actuator” is enclosed and hard to test. Actuator is NOT covered by warranty! To get to the solenoid connector requires a lift to remove the front left wheel. I’ll need to get one and haul it up to the farm next week. Thanks for the comments!

All batteries indicate 6.3 or 6.4 volts. The 45C3 code seems to happen less when operating in “M” mode. Better throttle control as well. I remain unsatisfied with the frequency of the “low volte cut” error code but appreciate the comments.

Thanks for that, Remy. I didn't realize that there was a 12 volt system at all! I will get to digging in on these suggestions on Sunday afternoon. Many thanks to all!

I get 6.3 volts at each switch pole. I haven’t identified the solenoid or actuator yet

This is an all electric SxS. There is voltage at the switch but I do not where it goes from there. Hisun will not let me see a schematic. Getting to and from my servicing dealer is a full day and $200 trailer rental. Hoping to get some guidance on where to look. I presume there is a solenoid and some kind of actuator. Anyone know what those look like? Pics? Thanks.

The dashboard display shows a blinking “o”. Four wheel drive does not engage. The accustomed engagement sound is no longer heard. Has anyone a suggestion on where I might troubleshoot? Thanks.

I thought it might be a trouble code. I checked the long list of codes in my manual but I was only looking for 45C. Is there a place where I might find the complete code for redlining the battery temp? Thanks

Our new Sector E1 electric has 45 miles on the odo. It frequently goes into shutdown mode after a few minutes of putzing around the farm. Instrument panel gives a flashing message “45C”. I presume that this means the batteries are overheated. The temperature indicator is maxxed. No stunt driving involved, just the grandkids bumping along in low range across the pasture. Of course, the owners manual does not reference this condition. We park it for a while and it returns to normal; at least until the next overheat. Has anyone else been bothered by this?
