Disable Regen Braking
I did a search to see if there was a proven method of defeating regen without any ill side effects,short of putting a motor on it that regen has been removed,all I found.The cart is a 2000 DS 48v Regen,the replacement controller eliminated the regen solinoid,the regen system now operates properly,but at very low speeds it seems to be choppy as if it were going in and out of regen.I'm sure unplugging the speed sensor will disable the regen but does anyone know if this can be done long term?
Second Question:no reverse horn,horn is good and powered,not getting negitive signal from controller when placed in reverse,I can provide neg with a relay but need a relay that will operate on 48v.May seem like a small deal but I can see me(after a few cocktails) or my lovely wife slamming into the motorhome.As always Thanx in advance guys!!!Dave |

Re: Disable Regen Braking
You can eliminate the regen braking from this cart by removing the solenoid located on the driver's side of the car. This is called the "Dynamic Braking" solenoid. Cut the two small wires attached to the solenoid and tape them up. Remove both large white wires from the solenoid and discard the solenoid (Or keep as a spare as a replacement for the other solenoid) Discard the white wire that ran from the solenoid to the A2 terminal on the motor. Hook the other white wire to the A2 post on the motor. You should now have a wire running directly from the controller to the motor. Thus, bypassing the Dynamic braking solenoid. This however, will not keep the regenerative braking from working. You must do this by unplugging the speed sensor on the motor. This will not cause any ill effects like you had mentioned above. I've done this on plenty of cars per customer request without any complaints at all. The surging you were describing is most likely caused by a bad speed sensor anyways. About the reverse buzzer... That's probably going to be traced back to the controller. Those things have so many circuits in them and it's not uncommon for some circuits to fail, while others remain to work perfectly fine. You've probably got a short in the reverse buzzer circuit. Not really a big deal for the operation of the car, but it's annoying if you want the buzzer to work. It's also very expensive.

As far as the horn,I rethought that, I can pick up a negitive at the pack gauge and positive off the reverse side of the F&R switch,no relay.I'm sure you read why I want it to work.Thanx again Dave |

Re: Disable Regen Braking
This may be a stupid question, but regarding the dynamic braking solenoid.....does is close to provide dynamic braking, or does it open to create dynamic braking (is it normally open contact, or normally closed?)?

Re: Disable Regen Braking
The controller actually provides the motor braking. The dynamic braking solenoid was just a way for Club Car to try and dissipate some of the excess heat from the process. It didn't really work very well, therefore they discontinued the second solenoid for the 01 Regen 2 cars and the 2002-Present IQ and Excel cars. The DB solenoid closes when accelerating. If not, you'd be trying to pump power through the resistor coil while trying to run. That's why whenever you find a DB solenoid stuck closed the car moves VERY VERY slow and the resistor coil glows red. It's designed to open the circuit upon motor braking and close upon pedal down.

Re: Disable Regen Braking
I found an easy way to disable the regen on my 2001 CC regen without anly wire cutting and hacking. There is a small cover on the rear (shaft end) of the motor held on by 2 screws. Remove it and there is a small round magnet on the end of the motor shaft. It has one small allen screw through the center, holding it to the shaft. simply remove the magnet and screw and put the cover back on. Thats it!
It's easily reversible by reinstalling the magnet. |

Re: Disable Regen Braking
OK so I may be missing it but how do I disable the regen on my 05 precedent? I think it has the code 3? because it runs 15-17mph with stock tires and only upgrade is 2ga wires. But I still feel the regen holding it back on the declines. If its going to hurt anything I dont want to do it but if its safe I want it gone!!
