Did you by-pass all 3 of the OBC functions?

Make sure You have at least 42v on you battery pack, measure from pack positive to pack negative battery posts.

If you do, it sounds like the OBC is completely dead since none of its circuits are working.

To by-pass the charger activation circuit (charger relay does not click):
Run the gray wire from the charger receptacle directly to pack negative.
To by-pass the charger current control circuit (charger clicks but no current flows):
Run a 10ga wire from the back of the charger receptacle negative wire directly to pack negative.
To by-pass the controller lockout circuit (no reverse buzzer or solenoid activation):
Disconnect the 6-pin OBC plug and put a jumper on the harness side connector between the Blue and the Red wires.
The first 2 by-passes will allow you to manually charge the pack until You get a smart charger to replace the OBC+Powerdrive charger. You will need to manually disconnect the charger once the pack gets up to 60v as measured from pack positive to pack negative.

The last by-pass will allow You to test the cart runs without the OBC, meaning there is no other issue.

Looks like someone has moved wires around the FNR switch.

I don't have a diagram for a 2005 Precedent, but this is a high resolution one for the 2004 Precedent.

With the OBC lockout by-passed, You should be able to troubleshoot the solenoid activation issue.

Do You have +48v from the solenoid light blue wire to pack negative with the switch ON?

Do You have +48v accross the solenoid small posts with the pedal pressed?
