How to Bypass On Board Computer | Club Car Precedent Golf Cart | OBC

[@williamhathaway7752]

Thanks Barry. This video saved the day on my 16 year old Club Car Carryall VI. The OBC would not allow my Club Car EIRC charger to connect, but after this simple modification, the EIRC charged my new Trojan T-875 batteries without issue.

[@scottbailey5797]

Did your charger show no load before you did the bypass?

[@briandubie4878]

Barry, Thank you for your great videos, I have 2006 CC 48volt, I put new batteries in it, runs good but will not take a charge, I have been charging each battery, Is there a way to test the OBC? or Charger? or plug? to determine which the problem? Do you recommend bypassing the OBC and going with a smart charger or replacing the OBC? after determining where my problem is. Thank you.

[@shawnquigley6310]

Thanks for this video, question would you do the same procedure when converting acid batteries to a lithium battery. Negative black wire to negative on lithium battery ?

[@celorenzo]

Great informative video, thanks! The black negative goes to which battery negative in a 4 battery 48 volt configuration? If you swap out your lead acid batteries with lithium what else is messasary (other than getting a new 48 volt lithium friendly battery charger.

[@rickbritton202]

Thank you Barry, you do great easy to understand videos. One question my Club Car Precedent is 2007 model, and 48 Volt. Once I cut the Neg from the Charging Harness, what Neg terminal do I need to attache the spliced on Eyelet to on my 48V model. Thank you

[@9RickC]

Hi Barry. I just did what you said and it is still not charging. I watched another video and it says that the gray wire needs to be deleted, and the white and blue wires need to be jumped together. What do you think?

[@bradleyslusser2279]

Do you use the same process on a Precedent that uses 4-12v batteries? Thank you

Be careful when you charge this set up. Have some sort of timer outlet and surge protector. Or just watch it full time.. DO NOT leave this plugged in you will regret it.

The video was very good explaining about bypassing the OBC but you you left out a very crucial point in which this information is very bright, you didn't explain why would you bypass the OBC, what problem persists when the OBC goes bad or what issues are you having in the golf cart to make the OBC a suspect,

[@saltysunburn2913]

How long do you typically charge a 48v carts for now that the OBC is gone? I have a power drive 2 charger and a 2011 club car precedent 48v. You helped me resolve my issue. I just made a jumper from the grey wire that normally goes to the OBC from the charger receptical. I left the fuse in path and jumped the new wire assembly to number 6 neg. My power drive 2 charger kept short cycling and dumping the charge after 5 or 6 minutes. I thought it was the charger. So, I replaced the rectifier, relay and fuse in the charger. The charger doesn't dump a charge anymore and runs around 8-9 amps.

Hi Barry thanks for the info, battery charger now charges but will not turn off, it continually runs at approx 15 amps and batteries reach a charge voltage of 58 volts, i assume the OBC originally turns it off once correct voltage has been reached.does the charger have voltage reading capabilities as well?

Hi Barry. Great video. I have a 2015 club car precedent and my original charger burned out. I bought a deltaqIC650 charger (set to charge program .003 for my T875 batteries) and it's not charging properly because of OBC incompatibility with my new charger. It seems like this work around should work. Any comments would be helpful. Many thanks. Lewis

[@PaulDinardo]

After storing my cart the batteries got low on fluid because of the heat in AZ. I refilled the batteries and tried to reser and it didn’t work, any help would be appreciated. Paul

[@nyguy4u]

So, I'm a bit confused by this. Every other person says beyond just moving the black wire to negative terminal on #6, that there are addition steps with blue and yellow cables, etc. Even OBC bypass kits come with multiple cables. What is the difference from your method vs the other methods?

[@galinpotter1690]

All you have to do is go to the back of the charger port and take the black and grey/blue and go straight to main negative on cart that way charger port goes straight to batteries and not obc only downside is if you don't have a new digital charger. If you have the old school heavy sob charger than you have to either put it on a timer or make sure you unplug it because it won't shut off and could do serious damage. The new chargers are a.fifth the weight of the old ones and they have a obc built into it so doing this isn't really a.issue

[@nickcoppard5335]

I have replaced the 36 volt on board charger .the new one only has 2 wires . What should I do the third wire on the golf cart . I believe that the wire is to stop the cart being driven whilst charging

I have everything hooked up correctly but in the controller software monitor, it shows the cart is plugged in charging (when it is not) and therefore won't run. The OBC was working fine prior to modifying... Do you think it is a damaged wire (from the install) going to or from the OBC or something else? Thanks for your help!

[@golfcartking]

I would double check the wiring diagram to ensure everything is in the correct spot. Did you make sure to leave the wire going through the middle of the OBC? This is a must. Also, you did put the cart into TOW before starting?

From UK. Hi Barry enjoy your videos, very informative. I have a 2004 Club Car electric 48 volts. It only runs at steady relatively slow pace, goes uphill same speed as on flat. Is it governed or speed restricted? And if so where is governor located and can I adjust for little more speed Cart only used on golf course.

The governor is programmed into controller. If you contact a local CC dealership, they can reprogram the controller for optimal performance.

[@sonjasanders9367]

Barry do you bypass the OBC if you want to switch to lithium . I would like to install a lithium battery kit and I believe I need to bypass or disconnect the OBC to use a lithium charger ?

Most likely. I know one of the lithium kits says it will use the factory charging system but a lot of them come with their own chargers that don't use the OBC.

The wiring for a 2003 Club Car Pathway is different. The black wires going to the OBC, controller, and front are all common to a single post, along with a smaller gauge wire (pink and black). Any insight on how to handle this model?

[@PaPaBobUTube]

I have the same model and about to perform the bypass. But, the diagram I have shows that both the black and the Grey wires from the back of charging plug need to be removed from the back the OBC and extended with a round terminal added and connected to the last Battery in series negative terminal. One will unplug but the other that has a fuse inline has to be cut. The one with plug is a smaller wire while the one with the inline fuse is a 12 ga wire. A little splice is needed. Before I do this I will be checking with someone because Barry here only talks about one of those wires being changed out.

I have a 2008 CC - 48V - 4battery setup. The cart will not take a charge nor run. Stock Cart and unmodified. From what I can read the OBC is likely bad.

I took the charger to a friends house and plugged it into his CC...works fine. Any thoughts?

[@itsfrito1]

Brannon Helms if you cart is completely dead the Charger will not come on as it does not know it is plugged into anything the minimum voltage for the obc to come on is 38 volts I believe if you have the 4 12 volt batteries you can individually charge each one then charge your cart

[@johnworkman5121]

Or you can take another 48 volt cart pull it beside the one that needs charged and with jumper cables connect both battery pack together main + to main + and main - to main - the charger will now see the voltage of the charged cart and come on after the charger starts carefully disconnected the jumper cables

[@stilltwostrokin]

Put to tow, get a charger with 40 amp startup and charge 2 batteries at a time on 12v setting for about 45 min. So 45min for2, 45 min for 2, 45 min for 2. Then charger will find them.

No gradual decline. Tried charger on identical cart and works fine. If I do the by-pass will automatically charge and slowly ramp back down as the batteries become fully charged?

Doing the bypass allows you to use a smart charger. If you bypass the obc, the charger you have now will not work.
