bad OBC???

djtuck · 05-07-2011, 08:20 AM

95 CC DS 48v. i have replaced the solenoid, resistor, diode, all microswitches, checked every wire for continuity and all tests out good. batteries are good, less than 1 year old, i have tested them. I have had my charger tested as well, from a CC dealer.

need to know if my OBC is the problem. Cart won't move, nor will it charge.

i can get the wheels to turn if i run a wire from the yellow wire on the solenoid to the negative terminal on #6 battery. wheels turn both directions.

charger clicks when i plug it in, but i see no rise in voltage across the pack. pack is around 49v with or without the charger plugged in. out of the charge receptacle i get around 55v, but its not getting to the pack. also, charger hums very quietly but the needle never moves.

i have a replacement OBC from CC still in the package in my garage, but i am hesitant to open it unless i really need it. (they said i could return it if i don't open it, and those bastards are not cheap)....

thoughts??

"...i can get the wheels to turn if i run a wire from the yellow wire on the solenoid to the negative terminal on #6 battery"

Sounds like a bad obc to me.

thanks guys!

are you gonna fix it or leave it bypassed?.............................

try resetting the obc first

i tried resetting it, no dice. i have an old one that came with the car, going to see if that one works before i open the new one.

any downside to leaving it bypassed, besides having to babysit the charger, of course?

honestly ???? no other than the OBC not telling the charger to be more specific about each battery voltage.........i know a few carts that have been bypassed for several years now with no issues but if it were mine and i had the cash i like things right...........if you forget about the charger just once it can be a costly mistake............................

I think chances are slim that you will be able to babysit the charger for years to come without under or over charging the batteries. Improper charging will shorten the lifespan of a battery.
I thought when you bypass the obc it is for a test only as the charger puts out full power only and not the 3 stage charge the batteries are designed to receive? Can any Club Car guy verify or dis-spell this info?
