I have a Ranger EV with less than 50 hours on it. Already had the voltage reducer fail and Replaced with newer model (known issue). Today I got in it and the High-Temp light is on and no power. Controller is flashing 8 times. Power to controller is over 50 volts. Isolator is latching fine. Don't see how it can be a heat issue beings it just came off charge and not been run for 24 hours. Looked up controller and found that pin 13 is for temp sensor. Traced wire and it goes to small gauge plug on motor. Wire is black w/ white trace. Tested resistance to ground and its open. Not even sure if the light is for temp on motor, controller, or batteries. Has anyone had this issue this is the second time this machine has taken a crap on me. Always when I need it most. I made a huge mistake buying this garbage.
