I have a 1996 DS club car 48 volt. It has a flashing orange battery light that is flashing on 5 sec and off 5 sec and on 25sec then repeats. All batteries and cables have been cleaned and charged. All wiring has been checked. It will except a charge from the charger about 50% of the time and at other times it won't because the light is flashing. If I disconnect the negative cable and let it sit for a few minutes the code goes away but then reacurrs at times. Also if I plug the charger in while the light is flashing it will stop flashing and except a charge. Any ideas what might be causing this erratic battery light issue. 
Any help would be greatly appreciated.
