To troubleshoot the Solenoid Activation Circuit on a 2002 DS Series cart:
The
yellow wire on the solenoid small post goes to the OBC and provides the
negative for the Solenoid.
The
White/Black wire on the solenoid small post goes to the FNR micro switch, Pedal switch, key switch and provides the
positive for the Solenoid.
Lift one wheel off the ground, turn the key on, put FNR in Forward and
press the pedal.
Set meter to 200vDC scale.
Measure the voltage across the solenoid small posts: Yellow (
meter negative probe) and Black/White (
meter positive probe) wires.
If You get +48v and the solenoid does not click, replace the solenoid.
If You don't get +48v, find out which side is missing:
Measure the voltage between the pack negative battery post (meter negative probe) and the Black/White wire (meter positive probe) at the solenoid small post.
If You don't get +48v, the micro switch in the FNR or the Pedal micro switch is the problem.
Measure the voltage between the pack positive battery post (meter positive probe) and the yellow wire (meter negative probe) at the solenoid small post.
If You don't get +48v, the OBC lockout is the problem. You can disconnect the yellow wire from the solenoid and ran a new 16ga wire from that solenoid small post directly to pack negative or Controller B-
