Run diagnostic?

[scottyb]

PDS Diagnostic Mode =
PDS Diagnostic mode can be entered with the cart stopped key 'off' though 5 consecutive neutral > reverse selections. Then pause = about 2 seconds after the 5th selection the reverse buzzer will emit a series of beeps... like 3 & 2.
Report what your cart reports here.
To exit diagnostic mode turn the maintenance switch from run to tow and back again

Maybe it is 3-1 Solenoid driver failure. You can check the solenoid activation circuit, this is also a possible controller failure code.

How the Solenoid works:
The solenoid is a HD on/off switch or Contactor
the connection is made /broken between the 2 large terminals. The 2 small terminals are the activation circuit. Typically one terminal will have a constant negative connection to the pack. When Positive power is applied to the second small terminal the contact is drawn up against the spring to make contact. When power from either side of the activation circuit is removed then contact is released and the spring pushes it away interrupting the circuit ...It doesn't matter which small terminal is neg or pos on the activation circuit so long as you have both.... The solenoid is just a switch making and breaking the contact between the 2 large posts when the 2 small posts have pack voltage.
I hope this helps.
