Charger not working

shanker

I have a 48 volt system club car and the battery charger is not charging the cart. First let me eliminate the obvious. The batteries are new, the wiring is correct, the inline fuse is good, the f & r fuse is ok and the charger works on other carts. When you plug in the charger you hear a click and the dial doesn't move and the charger doesn't come on, so there you go. HELP

what year? if charger is working on other carts and you have at least 38 volts in your system and all cables are good wires correct............OBC would be what i would suggest........................................... ....

obc.... make sure all wire connections are good on the obc. If its a precedent check the small grey wire and check the connection on the small black wire as well. if all is good you may have a bad obc(on board computer). $300 for a new one.

Its a DS and how would I check about the computer to see if it is good or not.

How many volts do you have across the pack? Was the charger working fine and you got new batteries and now it doesn't???

Is there anyway to check it before having to shell out $300 and it may not be the problem.

Sure.... two simple tests here and all you need is a jumper wire about 3 feet long.

--with charger plugged in... Separate yellow fuse holder. Leave fuse in receptacle side. Hook jumper wire from tip of fuse to MAIN negative battery terminal. Charger will click and turn on. If it does, control circuit is bad in OBC. This tells you the following; My car has enough voltage to communicate with the charger, and when I supply negative voltage to the control wire, the relay turns on. My OBC isn't providing this voltage as it should. I need to buy a new one.

--Often times charger will CLICK but won't charge, if this is your case, proceed... Re-attach yellow fuse holder. Attach jumper wire from either terminal on PLASTIC fuse on back of receptacle to the same MAIN negative battery post and plug in charger. This bypasses the CHARGE circuit that runs through the OBC. However, if your charger isn't clicking to begin with you've got an issue with the control circuit as well and definitely need a new OBC. This test won't tell you a thing unless you're getting a relay click.
