Default Reset the club car OBC

Good morning all,

I've been lurking for about a week now gleaning information from the wealth on knowlege in this group, but now I need to ask a question. How does one go about resetting an OBC? I've heard it referred to several times in different threads. I have some other general troubleshooting questions, but I'll start a new thread for them. Thanks for all of your help so far.

Default re: Reset the club car OBC

Copied from the alltraxinc.com website. They have posted a wealth of technical info there ........Let us know if this helps with your problem
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 down
The reverse buzzer will sound and go off in about 30
seconds. Leave the cart like that for 5 min to cause 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 Batt wire to the battery minus
terminal on the battery pack.
Once the OBC has been reset, the cart can be
troubleshot. There is always a chance the OBC has
completely failed and the reset process will not fix the
problem. Consult your Club Car manuals or contact
Alltrax for more troubleshooting of vehicles with an
OBC.

Thanks for your quick response, ScottyB.

I went to the site you recommended and found a schematic for the entire electrical system. The wiring diagram I have was great for making sure that all of the wires are accounted for, but did not help much with actual hook-up. I immediately printed the reset instructions and headed out to try it when I noticed that the tow-run switch is involved. What if I don't have one? It's not that it's missing...there isn't even a hole where there should have been one. I think that I'm one of those special cases.

On earlier model I would just ignore reference to run/tow switch if you don't have one

The black wire coming out of charge recepticle has a yellow fuse holder, open it up and connect a jumper from the end coming out of recepticle the the negative on Battery 6 or the last one in series. Plug in the charger if it comes on your OBC is most likely TOAST.

Check Battery pack voltage before assuming OBC is toast .

The charger does cone on when the control line is grounded. The OBC is toast the motor is reading 2.8Meg across the A winding (toast), and the controller won't kick on the other solenoid (probable toast). I know when to cut my losses. It's time to sell it for parts. Thanks for the help. I'll be back soon with another one. Hopefully one that just needs tweaks and flair, not CPR.

Also...battery pack voltage is 53V and individual batteries are within .5V of each other.
