Under charging battery's
I have a 2010 Precedent bought used from a dealer. The cart has 2010 Crown 8volt CR165 battery's. Was told by dealer these are OEM. When charging the volts never read more than 53. From what I gather the volts should read at least 58 towards the end of the charge cycle. I have two PD3 chargers and both do the same thing when charging. So I don't think it is my chargers. From what I have read the OBC controls the amount of voltage the cart is receiving and the battery's don't seem to hold a charge. So here are my QUESTION"S. Did I destroy my battery's by continuously under charging? Could it be a bad OBC? Or are the battery's shot and the OBC reacting to the bad battery's? I know I will be replacing battery's soon, not sure if I should dump the OBC and go with a after market charger, or should I try a new OBC and stick with the PD3 charger. Would like to do what's best if I am going to spring for new set of battery's.

Re: Under charging battery's
first check each battery for voltage they should be 8.49v each, if one is lower than the others it may be bad
also try an OBC reset then if you get the same reading run cart around for about an hour then do an OBC by pass and charge keep an eye on it and see if it raises above the 53v you had before if it does then OBC is not reading pack right .. if it stays at 53v then batteries are nearly dead .. a dead cell may be to blame |

Re: Under charging battery's
CTD, I did a battery check, this is what I got. 8.30 8.43 8.38 8.35 8.37 8.27 With a overall pack reading of 50.1 after about a 7 hour rest. I have tried the OBC reset more than once in the last few months with same results. The last one being yesterday. Never could get the reverse buzzer to sound (it does work). But I hear that is common. Going to try the OBC bypass. By doing the OBC bypass I assume you mean jumping out the charger? Thanks for the help.

Re: Under charging battery's
Are you taking the pack voltage while the charger is on? Does the cart run with plenty of power? Your battery voltages are good.

Re: Under charging battery's
to by pass OCB
DO AT YOUR OWN RISK.…do not attempt unless you are familiar with electricity and electronics! There are two ways to force the charger to turn on regardless of the OBC. The first method is to disconnect the cart’s gray wire at the fuse near the charger receptacle. Then using a jumper wire, connect the receptacle side of the fused connector to the cart’s negative battery terminal. This will energize the charger’s 48V relay. If the charger doesn’t come on, it could be bad connections, wiring or charger relay. The second method is to open the charger and remove the 120V wires from the relay and jump these together. This totally bypasses the relay and the OBC wire. (If charger comes on but the charger ammeter shows 0 amps, check the fuse at the charging receptacle under the clear plastic cover.) Both of these methods should both be temporary measures for troubleshooting, or as an emergency method of charging the batteries when they have been discharged so far that the OBC will not charge them. The OBC provides the optimum method of charging the cart’s batteries. If the OBC is bad, it should be replaced |

Jakesnake27 the voltage was taken with about a 7 hour rest.
