You still need to do voltage checks. The procedure is in the stickies. Then you'll know for sure if the controller is sending voltage to the ITS, and if the ITS is sending signal back. New components can fail out of the box. It's cheaper to rule things out, rather than throw parts at it. From what I've read so far, it sounds like you are not getting a throttle signal.

No I’m not getting correct throttle signal that’s why I replaced those as suggested by the Alltrax repair manual after testing. Afterward there was no change... they still tested bad. Only after I changed the FNR did the cart start to finally move. Now it moves intermittently instead of not moving at all.

I've gone back and reread and looked at all the photos again. The tow/run switch you referred to is going to the half speed reverse spade. Someone has added a switch to toggle the half speed reverse. Are you sure there are no connections in the white and black throttle wires. I noticed what looked like butt connectors on one of the pics.
Also noticed what looks like a frayed cable on the back of the forward and reverse switch.
I'm just drawing at straws at this point. If you're not getting a throttle signal, either one of three things is wrong, the controller is not sending the signal, the ITS is not processing the signal, or the wires are not delivering the signal. Check/ replace all connections even the spade connectors at the controller. Make sure those cable ends are good on that forward and reverse switch.

Appreciate it Mgray. I’ll do retesting this weekend. A couple high voltage do look frayed but they tested ok with full battery strength all the way to the motor.
There are repairs to the smaller wires that somebody made at some point I may just replace all the wires and see what’s what.
For some reason the connections at the controller box 1234 don’t match the wire diagram but if I arrange them to match then nothing works. I assumed somebody had a sense of humor during grograming lol

Spade 1 far right side powers up the controller logics it should come from the small red positive post on the solenoid. Spade 2&3 are the throttle wires from the ITS. Spade 4 is the half speed reverse. Should come from the reverse micro switch. It should be labeled that way on that axe control.

If it ever runs, the pins at the controller are correct. Download the Alltrax wiring diagram and you'll see they don't match stock controller. No sense of humor, just following Alltrax' wiring diagram, something you should have had before starting troubleshooting.

We've asked several times what your run/tow switch goes to, but never got a response. It's frustrating to keep asking the same thing over and over, so some folks stopped visiting this post.

Found the ITS wiring diagram from my collection. Used to have an AXE 4855.

You claim to have done this, but what are the results??? Saying something is good or no good doesn't help. Values are needed.

FWIW: The toggle switch shown in the picture has been misidentified as a "Run/Tow" switch. The orange wire from it goes to Pin-4 on the AXE, so it is a 1/2 speed switch.

Normally, Pin-4 gets pack voltage on it via MS-4 on the F/R assembly, but that would limit the added switch to only being able to turn 1/2 speed on or off during reverse, which is of little value. I suspect the added switch is being fed from a source that has pack voltage on it all the time, or all the time the key is on. That would put the controller in 1/2 speed so it could be driven by the kids or similar reason.

Bottom line is that the cart's control circuit wiring does not match EZGO or Alltrax wiring diagrams. Or at least the 1/2 speed and possibly the beeper portions of those diagrams don't match. The rest ought to be the same.

There are several ways to connect the high current cables that work and the cart does run at times, so they are most likely connected in one of those ways.

The LED on the AXE controller does turn steady green after the throttle type code is flashed (Four green flashes for the EZGO ITS type throttle ?????) That means Pin-1 is connected in a way that works.

That leaves Pins 2 and 3. The black and white wire to the ITS sensor in the pedal box.

Connect a DVM between the black and white wires while the are attached to the controller and measure the throttle voltage.
When pedal is pushed just far enough to make solenoid click, it ought to be 10V and when pedal is pushed to the floor it ought to be 6V

The LED does not turning to amber when pedal is on floor indicates the throttle voltage is not going all the way down to 6V, but if it is decreasing significantly below 10V, the cart ought to be moving.
