My 1982 club car moves slow, can someone tell me the proper way to test to find if I have a bad battery its a 36 volt system, with 5 solenoids, I have checked and replaced 3 of the 5 solenoids that weren't working and now I do hear them all clicking and there is some increase of speed as each one kicks in but not a whole lot id say it tops out at about 6 mph, and creeps going up a small slope, I did read somewhere once before where I should put meter leads on battery while driving, when I did this here is what I got, let charge over night 38.01 volts, flat surface pedal mashed 36.21, small slope pedal smashed 34.2 volts, sound like I got a bad battery but how do I tell or does anyone have a better way for me to test this?
