I found out on Friday that I actually still have a TPS in this cart. I was able to buy an adapter and import to locally and will be throwing it in today. I'm hoping that this will fix the problem and will keep you all posted.

Re: I2 Excel upgrade to Curtis 1268 Controller Problems
Okie dokie! Still not working but a different result atleast. Man I've pulled those center batteries so many times I'm becoming ripped! LOL.
I found out that I still had the TPS on the throttle and completed a conversion to the MCOR2 today. The 1,3 code I was getting before is gone. Unfortunately I am now getting a 4,2 code now which is for overcurrent. I did install a heavy duty solenoid. Maybe I mixed something up on the solenoid? I've got the light blue and white striped wire connected to the flat connector on the side of the solenoid that runs to the controller. On this same side I have one cable running to B-. The darker blue and white striped wire connected to the flat connector on the side with the positive cable running from the pack to the solenoid. Of course this side has the positive wiring running from the pack and another red cable that was originally split off the positive pack cable (green cable) on the original solenoid. I have disconnected the original low battery indicator that was hooked up on the cart to eliminate the chance of that affecting the controller. I'll get some j1-15 voltage readings tomorrow when my son get's home from his mom's house and can help me by pushing the accelerator. I appreciate all of you guys helping out with your wisdom and excessive brain power. Thanks! |

Re: I2 Excel upgrade to Curtis 1268 Controller Problems
That 4,2 code means "contactor driver" overcurrent.
You most likely have the diode backwards. The stripped end needs to be connected to the positive side of the solenoid coil (Light Blue wire coming from key switch). |

Re: I2 Excel upgrade to Curtis 1268 Controller Problems
Sergio... thanks for chiming in.
I switched the light blue wire back to the positive side. Still got the 4,2 code. I went ahead and checked the voltage on j1-15 and got the following readings, which I never got with the TPS, so there is some improvement going to the MCOR2. resting pedal is .53V fully pressed pedal gets 3.46V The battery low indicator is removed and shouldn't be interfering. One thing that may help with diagnosis. The controller shows no light at all when switch is turned to run and key switch is turned on. If I switch to reverse before hitting pedal I get no reverse buzzer. I put the f/r switch to forward and press the accelerator. Then I get the 4,2 code on controller. The reverse buzzer will now work as well. |

Re: I2 Excel upgrade to Curtis 1268 Controller Problems
No worries .... I didn't ground to the frame. All grounds lead to pack.

The positive side of the Solenoid coil becomes whatever side the stripped end of the diode is connected to. |

I do have pack voltage showing on j1-8. Now there is a new MCor2 so there shouldn't be a problem there. Seperate wire is run to the speed sensor. The black and yellow wires in the dash don't seem to have anything connected to them. If that is a black and yellow striped wire then I couldn't find it. Sorry for my ignorance but I'm muddling my way through. |

Re: I2 Excel upgrade to Curtis 1268 Controller Problems
You're correct.... sorry pack ground runs to B-. The one cable runs to the controller while the red wire and positive pack cable run to the + side solenoid. Obviously I am confusing myself while trying to write this up.
