All Club Car golf carts newer than 1995 have an OBC or ” On Board Computer ” in the charge circuit to monitor and control several functions on the golf cart. It functions like the on off switch on your wall to control the lighting. But in this case it controls the charging and drive system. If the OBC detects a problem in either the charging or drive system, it will shut that feature off. When the fault clears, the OBC is supposed to turn that system back on. Sometimes, the OBC does not clear the fault. When this happens, it can cause your charge circuit to not work and allow the charger to charge the batteries, or even the controller not power up or the solenoid will not engage.The reset process is easy to do, but can take a fair amount of time.Resetting the OBC To reset the OBC the following must be done in this order:• Key Switch to Off• Forward/Reverse to Neutral• Tow/Run Switch to Tow• Disconnect the Battery NEGATIVE (–) wire from the Battery Minus terminal on the battery pack.• Put the Tow/Run to Run• Forward/Reverse Switch to Reverse• Key Switch to On• Lock the throttle pedal downThe reverse buzzer will then sound and shut off in roughly 30 seconds. Leave the cart for 5 min or so to allow the OBC to reset.To reconnect the OBC back into the system:• Key Switch to Off• Forward/Reverse Switch to Neutral• Tow/Run switch to Tow• Reconnect the negative battery wire to the battery minus terminal on the battery pack. Once the OBC has been reset, you can trouble shoot the golf cart. There is always a chance the OBC has completely failed and the reset process will not fix the problem.
