[Slam 99]

I have checked all the fuses they are good
I have a manual throttle cable on it
Any help would be appreciated

Welcome to HEF Slam!

Your fuses may be good, but is the voltage getting to switch panel 2? Does the panel have a good ground?.

 

[Slam 99]

Yes

 

[mg2361]

There are two voltage supplies. You checked both?

 

[Slam 99]

No I have no lights on control panel #2 none of the buttons respond and it is stuck in turtle mode track only everything else is fine
I found a thread on here telling you how to read the codes on the computer my codes are 18-23-32

 

[mg2361]

18 - Failure of the PVC
23 - Not listed, did you read this one correctly?
32 - Short circuit of the Temperature Sensor

These codes will not affect your #2 panel. If you have voltage to pin's 1 and 2, good ground at pin 19, then I would suspect a bad switch #2 Switch Panel.

Thanks yeah I’ll double check the codes and 23 was one of them when checking those pins is that at the harness going to control panel #2

Yes. When checking the voltages, do it by backprobing (carefully) the wires at the connector. Checking the open source voltages (connector disconnected) only shows voltage potential.

I had a similar issue on my machine. One corroded wire in a connector in the armrest was all it turned out to be.
