Re: Charging System Troubleshooting
Thank you Don. I'd post a chart of common OBC part numbers, but they change every time a new version comes out so I suggest just asking me.

Re: Charging System Troubleshooting
I replaced my batteries and want to know if I should of reset my OBC after putting the new ones in. With the old batteries the charger would stay on till it timed out and I feel like it is still staying on for a long time with the brand new Trojan 8v batteries in. It ran for 14 hours last night charging and was still on when I unplugged it to use it. It is running at lower amps than with the old ones.

Re: Charging System Troubleshooting
What year of cart do you have? Having the batteries disconnected for more than 10 mins will reset the OBC most times...

Re: Charging System Troubleshooting
Jake is correct about the OBC resetting itself after it's been without power for a while. When you plug the DC Cord into the cart is there a delay before the charger turns on? There should be. If ever there isn't a delay, replace the OBC. Often, when OBCs fail, they get stuck in "ON" mode and the charger turns on immediately when it makes a connection. When this happens, the charger will never turn off.

Re: Charging System Troubleshooting
Ok, not sure about the delay or not. I did not pay attention to that. The cart is a 1998 Club car ds. I put new batteries and an OBC in it about 3 years ago. Since then I did some off roading and took where I shouldn't of. Because of that I have installed a new motor, 500amp controller, heavy duty F/R switch, solenoid, and cables. It is possible the water taken on while playing submarine may have affected my OBC. This might be the cause of toasting my old batteries.

Re: Charging System Troubleshooting
The first few charging cycles after a successful OBC reset will take longer than normal as the OBC is using a different algorithm in order to establish a baseline for the pack condition.
It is important that You have a single cable on your pack negative and that goes thru the OBC. Any other negative connections (converters, etc...) need to be on the other side of the OBC (controller B- side). |

Re: Charging System Troubleshooting
Ok, I have only charged it twice since I put the new batteries in. I have a 6awg wire running through the OBC and a 4awg wire running around it becuase it would not fit through it.

Re: Charging System Troubleshooting
4 AWG wire will fit through the OBC with no issue at all. I put 2 AWG wire through them all the time and it fits snug, but even that will fit. I'm assuming you're trying to put the wire through it with the terminal on it? You've gotta put the wire through the OBC before you crimp the terminal on the end of it. The setup you're running now will confuse the OBC because it can't properly monitor how much energy the cart uses during a charge cycle due to the fact that it has power running around it vs through it. You need to eliminate the 6 gauge wire and put a single negative 4 gauge cable through the OBC in place of it.

You need to build a 3-1/2" x 5/16 threaded stud and use 2 cables, one for each side of the OBC. http://www.buggiesgonewild.com/attac...g-obc-stud.jpg |
