Re: 1999 EZ-GO XI875 won't run
Looks like the HPD box is false, so the controller is in global shutdown.
HPD stands for High Pedal Disable, which prevents the controller from working is the throttle isn't at 0% when it powers up. If the pedal wasn't on the floor when the picture was taken, than the throttle was at 100% when it ought to have been at 0%. Measure the voltage on the black and white wires to the ITS sensor while they are plugged in to the controller. You should have 10V with the pedal up and 6V with pedal down. Since both the high and low throttle underrange flags are set, the voltage between those two wires is most likely less than about 5V, giving you a continuous 100% signal to the controller, triggering the HPD shutdown. |

Try resetting Auto-Cal. I got the same alarms on my SR48500 when I was messing with throttle wiring while controller was powered up. Resetting fixed mine.

Re: 1999 EZ-GO XI875 won't run
See if your cart has a 4 wire Molex connector on the cable from the throttle box to the wiring harness, usually located between the FNR and the controller/solenoid on a series TXT. Dunno if yours has this. It has two wires from the throttle MS and two from the ITS. It's a common problem with corrosion. If you have this, eliminate it and solder or butt splice.

Possible causes: 1. Wiring fault between controller and ITS sensor. 2. Bad controller. (If you have 0V at the controller end also) |

Re: 1999 EZ-GO XI875 won't run
I'm getting 0V at the controller between J4 and J5 (white & black). So the controller must be bad. Is there a place to rebuild Alltrax controllers? Or should I just break down and buy a new one?

Is it possible that a Global Shutdown would prevent controller from outputting any throttle voltage? Can a Global Shutdown be cleared? |

2. Alltrax controller are filled with a potting compound to make them waterproof and are not repairable. -------------------------------- Have to call Alltrax for that answer. |

They seem to have great after purchase service, from everything I've heard here. Luckily, I don't know. |
