I have a 4 wheel drive bad boy buggies that i changed from lead acid to lithium and now the machine wont move . I get a code on my sevcon 633T45320 controler that indicates either the motor is bad or the contactors are bad. I ve replaced both and i still gat the code. Wondering if there is a reset that needs to be done?
