I presume that the OBC is bad?
Somehow I've become the family golf cart mechanic...
My sister's cart (~98 48V DS) won't charge. It gets plugged in, the charger comes on and then it shuts off within a few minutes regardless of how charged the batteries are. We have tried 3 different chargers with the same result. I bypassed the OBC. Now the cart charges fine. I presume that there is no other likely issue other than a bad OBC? Assuming that is the case it is my understanding that she has the following 2 options: 1. Replace the OBC 2. Bypass the OBC, get a smart charger and sell the old one. Am I correct? |

Have you upgraded the battery cables?

Re: I presume that the OBC is bad?
Sounds like a bad OBC. The reason I asked about the cables is because a lot of times people will upgrade them and choose to run the new negative cable around the OBC rather than through it. That will cause these symptoms.

Can I drive the cart with the jumper in place? Or is there some sort of safety interlock?

yes you can run it with jumper .. but i would not remember when OBC is bypassed the charger will not shut off so you need to monitor charge carefully or you will ether over charge or undercharge batteries i think they need to be around 60v to be fully charged at shut off then should be 50.9v after 12hr rest get a DPI charger http://www.cartsunlimited.net/48v_Battery_Charger.html |

So now I have the same problem on my cart ('98 DS). I installed the jumper but the charger only puts out about 2A. The cart only had about a 40% charge at the time. Does anyone know why it wouldn't be putting out the full 15A?

Re: I presume that the OBC is bad?
Which charger are you using? What's the 5 digit model number?

I'll post the model when I get home. I tried 2 different model chargers.
