While we are complaining about parking brakes, I will note that the flat bar the pedal mounts to on mine bent when I pushed on the pedal too hard. I had to tear it apart and reinforce it. Even though we are bitching about the parking brake, my E1 has been the handiest vehicle I can imagine around my place. I have never regretted buying it. It is so easy to use day by day to use., much easier than a gas-powered rig,

R, next time it stops get out and see if the brake lights are on. The brake lights will shut off the motor and the brake light switch is problematic. May not be your problem, but is worth looking at.

Are you sure you need to replace it? These E1s have so much torque in low range that you can drive with the parking brake on and never even notice the brake being on If the brake light switch works you shouldn't be able to do that (It keeps the drive motor from starting if lit), but the brake switch fails fairly often (I have had 2 fail in the 5 years I have owned mine). If you drive it for a while with the parking brake on (like I have done on multiple occasions), it will quickly wear the pad and the brake will no longer hold. To fix it, Lift the cargo bed and find the parking brake (located just in front of the drive motor on the drive line feeding the front wheels), The adjustment bolt is on the front of the brake. Loosen the 10 mm lock nut on the adjustment bolt and turn the 10 mm bolt inward to adjust the parking brake. I have had to do this multiple times over the years to keep the parking brake working, but have yet to wear the parking brake pad out. If yours is indeed worn out, any Hison dealer should be able to order you parts, or possibly an automotive machine shop can reapply a new brake liner. The brake light switch is on the brake linkage behind the firewall and is kind of a bitch to change because of its inaccessible location.

My dealer gave me an electronic version of the service manual and I have sent it to Kingfish. I will see if it will upload here for others to use. I'm not sure if there is a more appropriate way to do this, let me know if there is.. 2015-2017 Service Manual - Sector E1.pdf

Everything you are saying doesn't make total sense. If your battery level indicator shows full charge then the batteries probably aren't dead, you have some other issue. A simple one that can happen is the emergency brake switch breaks (they are very prone to breaking. I have broken two.) and you are trying to drive it with the emergency brake on, or possibly the emergency brake is misadjusted or not fully released and dragging. Normally the motor won't run if the emergency brake light is showing. But if the switch is broken the motor can't tell that the brake is on. The electric motor has more than enough grunt to overpower the brake and drive the unit so well you may not know that the emergency brake is engaged, but it overloads the motor and can show a 45C3 error. Not saying that's it but it's worth checking. I would also suggest that you check the voltage yourself across all of the batteries with a multimeter. I think you connect from the positive pole on the first battery to the negative pole on the last battery. If I remember right the first battery is the rear row, center left and the last one is on the rear row, center right. Check it when it is fully charged versus when it is "dead". I am not totally sure but I would guess there should be about a 5 volt difference between the two readings if the batteries are truly dead. At full charge it should be above 48 volts. Your charger has to be set to matched to your particular style of battery. If it set to the wrong battery type it may undercharge or overcharge the batteries. Hopefully your dealer understands this. From what you have said so far I am not impressed with your dealer. Sometimes an independent golf cart shop may be a better choice for help. The technology of golf carts is fairly identical to the E1. I realize they may not cover warranty items, but they might be good people talk to if your dealer is incompetent. If you find that your dealer is incompetent or unresponsive go a step higher to the Aussie Hisun distributor for help. Hope this helps

Ok, Lets start with the obvious. Do you really have power? You may have tripped a CB or GFI. Plug an electrical device (drill motor, etc) into the cord and see if it works.

I just replaced the OEM Discovery batteries in my 2017 E1 with Trojan T-105's. The dealer reprogrammed the charger for these batteries. I use the E1 almost constantly around my farm, but seldom put more than a a few miles a day on the rig. As I don't need long range, it was recommended I stay with lead acid batteries as the cost became a significant factor. My question is it is better for the batteries to charge my E1 every night or to run it a week or so and take the charge down a ways before recharging.

That sucks to know a dealer is that unsupportive. They are in an ICE frame of mind. I would consider your problem to be part of the power train on an EV. I'd try to get a hold of Hisun directly and seek their help. It could be the rocker switch. It should be easy to check out with a ohmmeter. It wouldn't seem that a charger fuse would affect the rocker switch, but you never know.

My 2017 E1 has the original batteries. They have a lot of hours on them. Now that winter is upon us they have started giving the 4C53 error on up hills not too long after charging. I am suspecting I need new batteries and am not disappointed of the life this set of Discovery batteries gave me. I may see if they will make it through the summer. I am not at all dissatisfied with my E1, Next to zero maintenance, never have to worry about filling it with gas, changing the oil, or figuring out why the engine doesn't run right. It has never left me stranded except when I high centered it in a snow bank with nothing around to attach the winch to pull myself out, It is especially nice in the winter when you never worry about it not starting. Just get in it and go, any time, any where. It is true it isn't very fast, but I am not in a hurry. The range is probably nowhere near advertised, but I just use mine around the farm and seldom do more than 10 or 15 miles per day. It is also true that it has more torque than any gas unit of the same class, which comes in handy at times. The E1 gets used more frequently than any vehicle I own. I will probably replace the batteries with lead acid golf cart batteries as I am not worried about range, but am worried about the price of upscale, higher performance batteries.

Recently my E1 has some sort of failure with the parking brake light system. The light no longer comes on when the parking brake is engaged. It used to be that the motor wouldn't run if the parking brake was engaged at all. Now it will. The problem with that is that in low range the e-drive has more than enough torque to propel the vehicle despite the parking brake being on. I first noticed the problem when I smelled the parking brake overheating while driving. The bulb on the parking brake light is good because it comes on when I first turn the key on. I have been unable to locate the switch that activates the parking brake light. I called the dealer. He would not give advice over the phone and insisted I bring it in. They are too far away and it would likely tie up a couple of my days to do that. I adjusted the park brake as Gorj showed. So it holds stronger now, but unless you really press hard when you set it, low range will still override the parking brake. Anyone know where the parking brake light switch is?

I agree the parking brake is not all that great of design. Mine holds fine on a very steep slope, but doesn't always fully release. I frequently leave mine setting for long periods of time with the parking brake on and have never noticed any ill effects from doing that.

I have a 2017 Hisun Sector e. It is the most frequently used vehicle (including cars) on our property. I love the fact it is relatively maintenance free, and you can just get in it and go.... any time, any weather. Looking at your picture I can see they haven't changed much in the last 4 years (tires and decals looks to be it). I don't think I would like my rig for going exploring out in the woods because of it's limited range, but it is perfect for around home. My batteries are getting worn and don't provide the miles that they used too, but I plug it in every night and it will still easily last a full day for whatever I may choose to do. I only have a couple of minor complaints; 1) the long delay between turning on the key and the time you can put it in forward or reverse to go. If you put it in forward or reverse too soon it just sets there until you put it in neutral for several seconds the go into forward or reverse. Whenever someone new drives it for the first time they can't make it go because of this quirk. No one will ever steal it because of this 😊 2) the emergency brake doesn't always release fully and I sometimes have to pull it up a little further with my toe before it will go. Hopefully they have corrected those minor issues on the new ones

So what exactly will this "Delta-Q" software do for you?

My dealer gave me a complete and thorough service manual loaded on a thumb drive with the purchase of my E1. A dealer shouldn't have a problem with sharing one with you. As I would expect, there isn't a section on suspension squeaks. The unit is quite quiet. If the rig made any engine noise, you probably wouldn't even notice those squeaks. If you have greased all the fittings I would spray down where the shock springs rub against the shock body with silicone spray. My guess is that is where the noise might be coming from..

That is absurd you had to go through all that hassle , Cliff I bought my Hisun used so who ever owned it before never thought to provide the adapter. Sounds like it may not have worked anyhow. So I will keep on my list of things to make, and will do it as soon as I get done with the dozen or so items of higher priority for me to make.
