i have a 1994.5 ezgo 36 volt with 4844m alltrax controller tested, white wire .012volts wot .041, black .444 when sol. clicks 9.44v wot 5.49v . red 0v wot 36.7v, 0v in fwd, 36.7v in rev b+ 35.72 wot 37.42v b- 0v m- 35.7v 37.42v

i hope its the trottle senser but sound like controller?

ITS voltage for an AXE 4844 controller is measured between black and white wires.
Should be 10V at solenoid click and 6V pedal down.


Measure battery pack voltage.
Then place DVM test leads between B- and M- terminals on controller.
Should read FULL battery pack voltage when solenoid first clicks.

If it doesn't read FULL battery pack voltage, there is an issue in the high current circuit that is external to the controller.

If you have FULL battery pack voltage between B- and M-, press pedal slowly to floor.
Voltage should smoothly decrease to Zero, or very near Zero.

If it doesn't, either the controller or ITS is bad. (ITS test is give in the beginning of this post)

I will ck it tonight thank you

Black and white wire 9.3 v @ wot 5.4v
Pack 37.3v. 35.5v @ wot 37.2 v. This sounds like the controller?

Have you charged the batteries? 37.2V is around 70% charge.

1. I don't have the exact ITS specs for an Alltrax controller. But I think the voltages you are getting are in the ballpark.

2. The resistance in the cables, F/R switch, solenoid and/or motor, might be a little higher than it ought to be, but there is conductivity, so the WOT voltage between B- and M- should be close to Zero.

3. That is what the test results are pointing to.

I'd give Alltrax a call and tell them what you are getting for the ITS voltage and the voltage between B- and M-.
They might suggest some other tests, or provide your with better voltage tolerances.
