Controller Programming

Thanks Johnny, think I know what I did wrong—- I’ll recheck when this thunder storm blows over —- it’s a doozy

[Canuck2400]

Thanks for your help—— I guess it’s all for nothing until I can figure out how I lost all power to the controller—- there is power to the solenoid, but not sure which wire to check on the controller.

Check for battery voltage on J1 Pin-4. (Alltrax calls it C1 on the attached schematic.)

This voltage comes from the reed switch, or reed switch bypass.

Thanks Johnny, I’ll check that

[Canuck2400]

I checked the voltage C1 pin 4 and it is getting full pack voltage

[Canuck2400]

I checked the voltage on the switch wires —- with the key on
In forward— Orange wire .5v
Grey .4
Green .4

In neutral. Orange. 1.9
Grey. .5
Green. Jumps all over

In reverse. Orange. 1.3
Grey. .3
Green. Jumps all over

Thanks for any help you might offer

Attached is a drawing showing how the voltage gets into the controller and out to the switches and solenoid coil. It is for a stock PDS controller (Curtis 1206MX), but the voltage paths for an Alltrax XCT controller is the same except the voltage to the keyswitch does not go through the F/R switch first like it does in the stock PDS controller.

You've got battery voltage on C1 Pin-4, so the next place to look is C3 Pin-3, through the Run/Tow switch and then C3 Pin-4.

Get the battery voltage on the grey wire going to the F/R switch and one of the problems is solved.

Thanks Johnnie ——I checked wires pin 3 (red) is pack voltage and pin 4 (orange) just jumps around

Sounds like a bad Run/Tow switch. Clip lead 3 to 4 and see if it runs.

Then we can go after the other issues, if they still exist.
