Re: Problem After New Controller
Correct me if I am wrong, but in your first post you stated the cart with that same motor was doing about 24MPH when it was being fed from a DCX400 controller from a 36V battery pack.
The only changes has been upgrading to a XCT48400-PDS controller and a 400A solenoid. Now the cart will only do about 14MPH (3500RPM) Appears that correct field map is installed. Getting 100% throttle. (Green LED goes to Yellow with pedal on floor) ---------------- On then monitor screen, is the reverse switch selected when cart is going forward and will only do 14MPH? (F/R switch or motor miswired) |

Re: Problem After New Controller
JohnnieB, missed your question on the monitor reading and the F/R switch. I'll check that tomorrow and get back to you

Re: Problem After New Controller
Weird, that the motor will spin faster in reverse.
Maybe something happened to motor when the DCX fried. Or it might be something simple like the motor needing brushes. Motor is probably due for a thorough cleaning inside and out, new brushes and a new bearing. |

Good catch, JB. Controller could have wrong magnet count selected or it could think it's in reverse (reduced speed) |

If possible, before sending cart to shop, please record a data log and post it. There are a couple things I'd like to see. For instance motor voltage at top speed, field amps at top speed and some other stuff. |
