I think the solenoid must pull in and then drop out because it feels like it starts to move and then clunks like the motor has lost power.

If the buzzer sounds when You are having the problem, then the problem is after the Tow/Run switch.

If You can test pushing it, or let it roll by itself when You are having the problem:
1) If You have resistance, the problem is NOT the OBC lockout as it prevents the roll away brake from working also.

2) If it rolls free, You need to by-pass the OBC lockout next.[/B]
If When You are having the problem, make sure You have +48v at the green wire on the 2 pin MCOR connector.

If You do and the solenoid does not click when You jump the 2 pins:

You need to check the voltage at the yellow wire at the MCOR 3 pin connector. It should be near 0v and increase to +4.60 at pedal down.

If The voltage is higher than 1v or does not change, You need to clean and check all of those splices on the 3 pin connector.

If the voltage reads correct, the issue could be the controller itself having the solenoid driver shot.

Question Re: 2009 Club Car Precedent IQ

Raining here today so I ran the cart on jack stands. It took about an hour to 1 1/2 hours of running for 15 to 25 minutes sets of stopping and restarting before the cart started acting up under a no load condition. I check voltage on yellow wire and voltage was o v pedal up to 4.6 v pedal down, checked voltage through micro and had 50 v, installed jumper and that still did not keep it from dropping out of run. I found that under the no load run I did not need to toggle R/T switch to reset, just a few seconds of rest and the cart would run again for short duration's and then stop again.
DCX500 returned today with a new interface board and confirmation that the controller worked when ran on bench test.
Sergio if I understood your last post correctly, installing the new controller could solve this issue, so without objection, I will try that next.

Thanks and here's hoping

Installed the DCX500 IQ with new adapter board and cart is on the road again! A little jerky when I start off in forward and reverse but not bad, however roll away alarm does not alarm now and I don't feel any regen braking when I decelerate going down hill. Is this common when replacing the stock controller with the Alltrax?

I think the Alltrax disables regen braking. I wonder if you can change the throttle parameters to make it smoother?

There is a setting that can do that with some limitation.

You control the regen braking with a slider in the software. It also controls the roll away braking. My take off was real jerky also but I got it down to a usable condition by setting throttle up to 3 and down to 5. It will still jump every once in a while. It also seemed to help when I disabled HPD. I don't know why but it did.

So I guess I would need a laptop with software or some type of programmer to adjust program in the Alltrax? After reading some other threads it appears that the regen braking in bypassed on several different upgrades to gain speed, I had already suspected that might be the case with this controller. I was surprised by the roll-off alarm not functioning, but if the speed sensor input is altered to get the stock motor to run faster, could that be the reason?

I would say that before you can go any further you need to be able to hook your computer up to the controller. Unless your happy with the settings you got.

The alltrax DCX controllers don't use a speed sensor, I think they should have it as an option (although it does appear the new models will finally support it).

The DCX does Regen braking for pedal up, and as mentioned, it can be adjusted for intensity.

Anti-roll-away is definitively way inferior to controllers with speed sensor feedback.

The Curtis OEM controller will have a pulse after only 1/48th of a wheel revolution, the Alltrax on the hand will have to have the motor armature turning long/fast enough to have measurable current.

If You push the cart long enough, the altrax controller will detect the motor is turning and the roll-away brake should kick in.
