Hello,
I have a 2019 Landmaster 550 UTV. Its been running good until now. The front axle wont engage. Where I live the temps have been well below freezing. The UTV is stored in unheated garage. And even the bottles of stored windshield washer fluid are frozen solid. So I am thinking that the front axle gear oil might be VERY thick and now allowing it to engage. Off the front diff is a small gauge wire running up to a connector. I put a test lamp to one of the leads and with utv running and 4 wheel switch on there is no voltage. However if I shut it off and have the 4 wheel switch engaged. and the crank it to start again the light gets a signal. for a second or two. I have to jacked up on rear and front and sometime the front will cut in and spin a few revs but the drops off.
Im hoping that someone can explain how the front engages on the axle. I assumed there was a fork or something that was engaged with 12 volts. But this wire is very small .This unit doesn't have a central fuse panel but I believe I have checked all the fuses.
Thanks in advance

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

We are doing a total rebuild of a 2010EV includes chassis refurbishment with a lot of new steelwork, blasting and powder coating. We have put the main front to back drive shaft in with new UJs, and its showing that the front yoke flicks and clonks and has a lot of movement on the spline. It moves sideways/ flicks is the only way I can describe it. Not something I have seen before. A replacement yoke has been ordered. Any thoughts as to what the cause could have been (other than a previously seized UJ at some point) ?
