    The batteries were charging for two days straight . After I put the tac drive in. I switch joysticks with the telescope to see if it was the joystick not working right. But no luck .I forgot to check the voltage with the machine jacked up.To what happens.All other functions work great but the drive .Machine does the same thing forwards or backwards.

    All I know is what I've found by experience. In most cases, when you have problems with electrical machines, one of the first things you need to establish is that the supply voltage is good, static and under load. On a 48V machine, you could have just one cell on one battery defective and it can affect drive operation. On electric machines, low voltage or battery problems will affect drive before it affects other machine functions because drive is typically the only operation controlled by motor contoller, such as a Sevcon, and a motor controller will shut down drive motors if the voltage drops below a certain point.

    I was thinking the same thing that night when I got home.I will have to go back to the machine .I will do the voltage test ,battery cell test and load test on the batteries. At least the machine is a heated garage not out in the snow.

    I hope you have some luck with it. I really don't know what to tell you on that machine, have no experience with them. :)

    Just a thought but have you disengaged the travel pin locks on each hub? They're located behind a cover plate in the outside center of the wheel.
