ok I have an update but its not really a helpful one. I replaced all the wires on the battery's and the fuse coming from the charging port. also the ends from the charging point. basically every wire end that was left on the cart I cleaned or replaced them also. plugged the charger in and still the same thing. so I drove the cart until it wouldn't go anymore. plugged the charger in and it went to working. charged up to around 49 volts, I know this is not a full pack, and then did the same thing where it hums but doesn't show that it is charging. now I am guessing that the battery's are just not able to hold a charge anymore than 49 so witch means I will have to replace them. dose this sound right or would you think I could have some thing else going on, battery's aren't cheap.
