Curtis Controller flashing 3 and 4
I am having a problem with cart not going forward Curtis controller 1266, my previous post. Had it with an auto electrician who did not manage to get it right. At one stage he said the led flashed 3 and 4. When will I see the error flash on the controller?

You may find your answer with flash codes, but you might have better luck with a programmer or the programming cable and a laptop running the diagnostics software.

I don't think the controller has an LED

Re: Curtis Controller flashing 3 and 4
I don’t think so either. If the cart runs in reverse but not forwards then it’s a controller issue or it’s not getting a signal to go into forward. Check pin 12 for pack voltage when the cart is in forward. If it is there flip the cart to tow, remove the pack negative and swap S1 and 2 on top of the controller. Don’t let them touch anything. Once swapped put the negative back on and flip to run. Will it go forward in reverse? If yes the controller is done.

Re: Curtis Controller flashing 3 and 4
Thanks. Swapping S1 and S2 has exactly the same problem but in the oposite direction. Unfortunately I cannot find someone with a tester around here to confirm that it is definitely the controller.

Re: Curtis Controller flashing 3 and 4
Does your cart have the 1266A or 1266R? If it has the 1266A try pushing the cart with the run/tow switch in the run position to see if your speed sensor works. If it is working the cart will get harder to push and the beeper will start beeping. My speed sensor occasionally stops working for some reason and when it does the controller acts screwy.

Re: Curtis Controller flashing 3 and 4
What are the differences between Curtis 1266 and 1266A and 1266R. ?

Re: Curtis Controller flashing 3 and 4
1266A has the walkaway feature; 1266R does not. Walkaway is when the controller detects cart movement via the speed sensor when the pedal switch input is off and activates motor braking (regen) to bring the cart to a crawl or stop. So if you push the cart and the speed sensor is working, the controller will see the pulses and activate regen and beep the beeper. If that doesn't happen it's a good indicator your speed sensor is broke.
I think carts with the 1266R can have walkaway with a mod, but I'm not sure exactly what that is |

Re: Curtis Controller flashing 3 and 4
Only a 1266 no a or r. Could the H and L switch be my problem. Trying to eliminate all possibilities before getting a new controller.

Re: Curtis Controller flashing 3 and 4
Have worked out that H and L switch gives voltage to mode on controller. This is not my problem.
