Acceleration Problems '09 Precedent
Hello All,
I have a 2009 Club Car Precedent. It has a new style pedal group with an MCOR 4. It has the gray controller with six brand new 8 volt batteries. I drive the cart and has a flat spot at full throttle. I hook up to programmer at 3/4 acceleration pedal I get 100% Throttle. If I go past the meter drops to "0" and cart drops off. I tried 4 different MCOR 4 and all did the same thing. I replaced the controller with a know good grey controller. No change still goes to "0" at full Acceleration. I replaced the magnet in the speed sensor. The cart appears to had wires cut and spliced to wire in the MCOR4. The conversion kit on line shows the wires in the correct location and color. I rewired and replaced all the butt connections going to MCOR4. Would the Butt connectors mess with the MCOR4? If the pedal travels to far does that cause the MCOR 4 to go to "0"? I'm at a loss and cant figure it out. Any ideas at this point would be great. Thanks Tom Baffled in San Diego! |

Re: Acceleration Problems '09 Precedent
PingEye, I'm not questioning your reply, I just have a question. I thought the 2009 Precedent had those resistors already in the main wiring harness since it was the year that they first installed the TPS. When I converted mine (removed the TPS) I just used the kit David sent me and spliced the wires to the connector.
I know you have to use the resistors on a Excel cart, but are they always required on a 2009 IQ cart? |

Pingeye3,
So many thanks!! I placed the 3 resistors in line it worked fantastic. A perfect 100% on the read out at full throttle. I appreciate the help and wisdom. Thanks, Tom in San Diego!! |

You are welcome, glad it worked out. I got that info from David at Revolution Golf Cars. He is the guru.

Re: Acceleration Problems '09 Precedent
The 2009 IQ carts just needed an adapter without the resistors...
