Hello. I have a 2016 Massimo MSU 500. I was putting on a lightbar and i screwed up and didn't disconnect the battery so when i was taking of the positive cable to put on the power from the lightbar it sparked and now the utv has no power. I turn the key over and all i hear is a chirp. No lights or anything. Everything that comes from the battery to the jumper box up by the battery shows voltage but anything coming out does not such as to the winch or anything like that

Just bought a brand new 2022 (NOS) Sector E1 with Lithium upgrade. (Single 135ah/200amp continuous). I've climbed a moderate hill in my woods probably 20 times since buying it. Today It won't climb it unless I am in Low. In High it almost makes it and then completely dies and I have to roll back down the hill. In Mid range (Max Range) I can't get 2 feet up the hill and the power output in only 100 amps, I have climbed this hill in every speed before many times. I put it on the trailer tonight and it wouldn't even get on the dang trailer in mid range. Torque is gone. That being said, when I am just cruising around in Midrange, it runs absolutely perfect with plenty of power. The only thing I did was charge it up, that is all. I charged to 100% using the charger that came with the battery. Before you think the BMS is shutting down due to overcharge protection, remember I am going UP hill so there is no regeneration AND I have done it before at 100% charge AND another big problem is that after 1 mile it is already down to 85% so it's not over charging and why is the battery draining so fast when I got 27 miles before. Battery output is fine in Low it pulls 200 amp up the hill just like normal so that doesn't point to the battery being the issue. All the individual cells on the battery are in line, so there is no dead cell either. I am tech savvy but to toward electric motors and I tried to cover all my bases. Please don't tell me basics like torque is reduced in High and Mid. The only thing I can think of is that I smelled something when I took my first drive today and I thought it was the Ebrake dragging but there was the correct amount of play in the cable and I jacked up the rear wheels and they spin freely. maybe something burned out in the motor, I do not knowm still runs great, we'll see if I have any trouble on the hills at the lake house this weekend. Maybe this is "Normal" and the settings were off before and was giving equal torque for whatever reason instead of 50% in Mid and 70% in High like the manual says....
For reference....this is it not even able to get on the trailer in mid range

The steering shaft is slipping,I checked it's tight as the bolt will take at the u-joint.. Is there a slot or something it may have jumped? This is right after the shaft enters the area under the hood.Thanks.

the regen braking on my e1 has stopped working unless (for eg) I am going down a hill in low and it's slowing things down to stick to the 10kph limit. when I drive and take my foot off the accelerator it's not initiating the regen to slow things down and instead just coasts at whatever speed it is at, or speeds up as the regen is not limiting it. the brake lights work, so it's probably not a fault with the sensor on the brake pedal
hoping someone else might be able to provide some suggestions on things to check, as the mob that I bought it off seem to have gone silent on me
