alltrax error code high throttle input underrange

ELECTNUT · 05-17-2018, 04:14 PM

I have an alltrax 500 that ran great for a year. Now it is stopped and I am getting this error code.

The MCOR may be going out on you.....

Here are Alltrax ideas:

-The throttle could be faulty
-Wiring/connectors
-Incorrect throttle set in the program
-Otherwise, Clear throttle auto-calibration and try again

Thank you for your response. I replaced the mcor and checked the wiring.
I cleared auto cal and even reset the controller. I started checking the solenoid, with actual help this time, and think it might be the culprit. I thought i heard it clicking before but i was wrong. Im going to pull it down and remove the resistor and check it.

Remember your solenoid will not close in if it is not getting the throttle signal from the MCOR and the Neg from the controller.

Leave the resistor OFF since the XCT does not use it.

Add a "Regen" diode which is a 6amp (6A10) or 10amp (10A10) diode on the big posts with the striped/band side towards the battery.

We may have found the problem

MY CONTROLLER IS 2 YRS OLD. I THOUGHT ONLY THE NEWER MODELS DIDNT NEED THE RESISTOR.

I WILL PULL THE DIODE AND CHECK VOLTAGE ON THE COIL SIDE OF THE SOLENOID.

I appreciate everyone's help and patience with me.

None of the XCT used a precharge resistor. The early models (2015-2016.5) did use the spark arresting diode. But sometime mid to late 2016 The manufacture got smart and integrated the diode into the controller because so many people left it off or worse installed it backwards. This small diode is different than the resistor we are asking you to remove from the big terminals.

Technically - to be current, you should replace the pre-charge resistor with a 6a Regen diode which safeguards the system in the event the controller looses power while the cart is moving.

Just wanted to make sure because the build date on mine is 3/16
