Gorj, did you sort out the "nothing coming out of the charger" issue? Thanks!

I'm speaking speculatively (as in I have not done this). The Sector E1 uses the Sevcon Gen4 controller. You can get PDFs of the Sevcon manual; according to the manual, you can set limits on the regenerative braking maximum current. That said, 400 amps of current is a lot of regenerative torque/braking!

Yes, Joe--when braking very hard, locked wheels will travel faster over pavement (or dirt, mud, etc.) than rolling wheels. If you're interested in the details, look up "coefficient of kinetic friction." If you're not braking, you still have control issues--the skidding wheels do not steer, and do not resist sideways motion as well as the rolling or driving wheels (the math gets really hairy for me, look up "nonholonomic systems"--that's where I gave up in school 🙃).

When wheels lock (usually the rear), the locked wheels usually break loose from the pavement, and will want to go faster over the road than the non-locked wheels. If they are the rear wheels that go faster over the road, your UTV will go sideways. If you slow down and/or steer poorly, you will get a moment (a torque) that may tip you over--especially if the UTV is top-heavy. I guess I'm getting confirmation bias to continue not to wear a helmet, especially when riding in my wooded 8 acres to collect downed trees and/or cut undergrowth, dead trees, etc.

Gorj, have you seen the posts about the inline fuse above the batteries? For example

Good luck! I just got a Sector E1 a couple of months ago. The only use will be spring-thru-autumn for firewood collection. I'm at about 9300 ft altitude, and in the winter, we get more than 150" of snow--the E1 will be outside (with a cover). I'm hoping the batteries will survive 3-4 months of winter (I'll charge them before parking the unit for the winter)--and that neither mice nor pack-rats decide to make their home in the battery compartment 😜 Please update if your intermittent comes up again!

That's the question! Or, if you want to add details: (a) How do you use the UTV? (roads? off-road to get to trees? etc.) (b) If you are wearing a helmet--how frequently? What type of helmet? My own answers: (a) Most of the time off-road to get to downed trees, cut the trees to logs and haul the logs back for splitting. (b) Very rarely, a ski helmet and not a motorcycle helmet.

Hello, according to the manual, the 54C3 error looks like: 54C3 | MOSFET s/c M1>B+ MOSFET | IGBT s/c detection on M1 top devices The IGBTs are part of the electric power switching system for the main drive. M1 indicates one of the phase wires going to the motor. Since it's intermittent, I suspect dirt, corrosion, or contamination on the electrical contacts. I'd think about cleaning the contacts. I'd suggest using personal protective equipment (nitrile gloves, maybe leather gloves on top of the nitrile gloves), safety glasses at a minimum. Unplug the charger, make sure the key is off and removed. Then, I'd suggest removing the seat, and using a DRY toothbrush (or similar plastic brush) and brush all the contacts on or near the motor controller module (and the main contactor/relay/solenoid). (This is a black module fastened near the middle batteries). I'd also think about using a compressed air gun (don't let the tip get near the batteries or any of the contacts!) or a spray duster and spray around the contacts at the motor controller. Then, I'd go to the motor itself, and look at where the wires are attached--see if you can see crud, dirt, corrosion, etc. and clean around the motor and where the power wires connect to the motor. Good luck, and please let us know how things go!

Update: my dealer found the remote. Serial number matches the receiver module. I've picked up the remote but haven't tested yet.

Well, it looks like there is a winch remote receiver mounted under the front hood. I just contacted the dealer to ask them if they forgot to give me the winch remote transmitter, or if that's an upcharge. I'll update when I hear from them.

It's not immediately obvious to me how to wire a remote control (wired or wireless) on the Sector E1. Has anyone here done this? Do you have pictures on how to get to the wiring? Thanks!

Hello, The engine lubrication oil is not the same as the transmission/differential oil. The engine oil does "bathe" the clutch. When you change the oil, there are different intervals for the engine and for the transmission/differential case. The oil types are also different for the engine and the differential case. Best regards.

Hy (pronounce he), just bought a Hisun Sector E1. I'll be using it to haul logs and stuff in the Sangre de Cristo mountains.
