Power wise Charger Qestion....
My kids got finished riding the cart this evening and they pulled it in my shop and plugged it up and got nothing. I quickly opened it up because I have batteries that are less than 2 weeks old and don't want them sitting around half charged. After inspection, I bypassed the relay on the circuit board and it came on.
Questions are: 1) Does this mean the board/relay is bad and needs replacing? Could it be anything else?? 2)Will the charger still time out with the relay being bypassed manually or will it stay on indefinitely?? I have it on an outlet timer just in case....... |

Re: Power wise Charger Qestion....
It was at 37.4 volts when they got off the cart? Wouldn't that be enough to allow it to come on??

Re: Power wise Charger Qestion....
I just checked the cart and unhooked the relay bypass I had made. It did immediately turn on normally. My question is why would it not turn on initially and what would u do if u were on vacation or something and the charger decided not to turn on?? What options would u have with your tools at home? I'm considering installing a manual bypass as a precaution. Any other ideas?

The control board in the charger senses battery pack voltage via the Aux contact in the charger plug touching the outside of the B- radsok in the cart's charger receptacle. If the voltage isn't sensed for some reason, or is below about 27V (36V charger), the control board won't energize the relay to apply AC to the transformer. As Simple man said, with the relay bypassed, the charger will stay on forever. Personally, I don't believe adding a bypass switch is a good idea. |

@ theclintonsx4, I would follow " JohnnieB's " advise on your charger! He is very knowledgeable about electronics in general. I totally forgot about the connections in the plug and receptacle! I just replaced these on mine too!

Re: Power wise Charger Qestion....
I'll check the plugs and clean them. I'm just not clear on why it wouldn't work at over 37 volts but 15 mins later it works fine? I never you,he'd the plugs on the cary, I only removed my jumper so i don't think it could have created contact if there was none originally because the plug never moved?
