Hey you guys,
Your input has been awesome.
I really appreciate your help. Problem solved. 1st there was a loose connection and secondly the pot was not giving full throttle. I fitted an ammeter and I tried driving using a 5k pot and turning it by hand. Man this controller is just great. Pulls 350 amps and nearly lifts the front wheels off the ground.
. That was with 60volts. Now I must try it with the full 120volts.
I will keep in touch. I now need to tidy up the wiring and put everything in its right place. That will keep me occupied for a while yet. \ Once again, thanks to all for your help.
Doug.
