Does your Club Car Precedent IQ or DS IQ go into a "limp" mode?
Do you find intial movement fine, then goes slow? It may be your Speed Sensor.
To conduct simple Speed Sensor test;
- On flat level ground, make sure you have ample room to drive.
- Check your batteries are clean and charged.
- Check cart is in Run.
- Turn ignition on and depress accelerator pedal to activate controller logic.
- Hop out of cart and push the cart to replicate "Roll Away".
If "Roll Away" function not present, you will either have a faulty Speed Sensor, Speed Sensor Magnet or a break in the wiring.
If "Roll Away" function present, but your speed fluctuates up and down throughout pedal depression. Or the controller stays in "sleep" mode.
You may have a faulty MCOR. Recommend to have your golf cart repairer to confirm diagnoses.
