Hi, Yes the problem is persistent. Hi-speed is no longer coming in at all, I have had the truck powered-up with key-on since my last posting and hi-speed is still not functioning. Intellidrive card displays 2-4-5 during acceleration and stays at 30% or so of top pulse speed, M-range does not engage and M contactor does not come in. Again adjusting the VR3 pot does change this speed slightly but not much so it must be into thermal or overcurrent cutback but I cant find the cause.
