I'm not sure if the correct ITS checkout procedures for aftermarket controllers are in the stickies.

The thing to remember about the ITS throttle system is 2/3 of the circuit is in the controller, so each make/model controller has a different checkout as well as different mechanical adjustments in the Pedal box.

The same ITS sensor is used, but it is fed power from the controller and the returned throttle signal is decoded by the controller. Making things more interesting, the ITS sensor is patented and to use it without paying royalties, aftermarket controller manufacturers have to use it differently. Apparently Alltrax feds it with a constant current source while EZGO (Curtis) uses a constant voltage source, the net result is when connect to a Curtis controller the throttle signal voltage increases when the pedal is pushed while when connected to an Alltrax controller the throttle signal voltage decreases when the pedal is pushed.

It is. That's why it was suggested, as well as many other things.

http://www.buggiesgonewild.com/elect...e-testing.html

"Alltrax SPM, SPB, AXE & NPX controllers, measure the voltage between the two throttle pins (see pictures below) with the key on and the peddle depress just enough to active at the foot switch. You should hear the solenoid close at this time and have a lit LED light. You should see 10 volts on the throttle pins. Press the Pedal down to the floor, full throttle and you should see 6 volts."

The cart is working today so I can’t do any tests. Funny thing about that toggle switch tho, I did take a look at that again and while the continuity cuts off when it’s switched off it doesn’t act like a tow switch that cuts the whole cart off. I switch it off and on and the cart moves in both positions when I bump the peddle forward or revers. I couldnt test johnnies theory today about half throttle but it would make sense about reverse because it easily squalls a tire if too much peddle in reverse.
So like Johnny said that leaves the black and white wires going to the throttle which I’ll test next time the cart quits.

Yurtle I’ve already told you the wire diagram matches and that it’s the orange wire that has the toggle switch and that only the 1234 ports on the controller box don’t match. Therefore the orange wire leaves the Alltrax controller box goes to the toggle then goes to MS4 on the FNR switchsame as the diagram.... except there’s a toggle added.

If you told me, then I missed it. Obviously JohnnyB did too, given his assumption it's a 1/2 speed "kiddy" mode, which it isn't from your description.

That would put the controller in 1/2 speed so it could be driven by the kids or similar reason.
Which pin on the Alltrax does the orange wire go to? If it matches the attached for 1/2 speed reverse pin 4, then goes to beeper AND MS4, then it's simply a 1/2 speed reverse kill switch, and not a 1/2 speed "kiddy" mode.

To get "kiddy" mode, like JohnnyB said, you'd need to apply pack + to pin 4.

Can you please list the things you replaced, one last time?

You've either got:

an intermittently loose wire/spade connector,
an intermittent key switch or microswitch
a failing controller

I'd suspect a loose spade connector first. If it can stop working then start working by doing nothing other than letting it "rest", without touching anything, I'd suspect a dying controller.

You can do the throttle voltage test we've been asking for. Maybe it's not blue enough, but the next line is a link you can click on.

If it's the same as the wiring diagram then does the 1/2 speed beeper connect to the orange wire or to MS4? MS4 provides pack + to the backup beeper and to the controller, telling the controller to only apply 1/2 of the throttle position, so 100% = 50%. Does flipping the toggle switch limit WOT (Wide Open Throttle)? This may explain why your controller doesn't go amber with the throttle to the floor.

I found this on Alltrax' website. Prolly no help but who knows?
