2002 TXT PDS 36V, Slow Motion

Croqezgo · 10-07-2019, 09:19 AM

Hello,

I have 2002 EZGO TXT 36V with PDS drive. The cart was flooded a while back (apparently). I replaced the controller, Solenoid, new batteries, some wiring. The cart runs just fine sometimes, but other times, it just goes very slowly. I did perform a reed switch bypass to make sure that was not the problem.

When the error occurs, it is sometimes fixed by letting off of the pedal, switching to neutral and back to forward, and then pressing the pedal. Then it may happen again if I let off of the pedal and press it back down.

The cart goes full speed in reverse with no issues....

Also, of note: The F1 and F2 wires are switched regarding color (aka one that should be black is white and vice versa. I did confirm that F1 on the motor is connected to F1 on the controller and F2 as well. I guess this is just a misprint in the wiring diagram? Any suggestions are greatly appreciated. I wonder if the speed sensor is messed up? I also replaced the micro-switch in the throttle box.

Which speed controller are you asking about?
The Alltrax XCT controller LED will indicate whether a full range throttle signal is being received by changing from green to orange at full throttle.
The free software for this controller allows you to turn off the RPM limit function which basically eliminates the the speed sensor from the mix. Deselecting limit rpm allows you to determine if the speed sensor is a problem or not.

I just replaced the old controller with another stock controller. This is a 2002 TXT. There are no LEDs on the controller that I see. 1206MX controller.

Does the reverse buzzer work in reverse ? If so does it start beeping when this happens ?

The reverse buzzer does not work. I believe it is not functional. I thought about replacing it but was not sure how to get to it as it is behind the forward/reverse switch and battery meter. I guess I could drill out those rivets and then replace with some kind of screws?

The rivets are push rivets. Replacements are readily available. Drive the center pin through with a nail, etc

Thanks Scotty. Any idea what could be causing the speed to be slow in forward?

Thats why we need the reverse buzzer working, so the controller can tell you what its idea of the reason for slow operation is. It can "beep an error code" for what it thinks is wrong.

Croqezgo · 10-07-2019, 10:35 PM

I ordered a buzzer, it will be here tomorrow night... We can then see if it beeps. Is there a special way to make it beep or will it just do it when I try to drive it?

You will turn the Run/tow switch to run... you will turn the ignition switch to off... then you will turn the forward/reverse switch from neutral to reverse and back 5 times... then listen to the beep pattern
