Picked up the cart 2 years ago for free, placed in the batteries and off we went.. Now the batteries were not charging and noticed wear on the lester charger addaptor on the cart.. took it out to clean it and it fell apart, while looking for this problem i removed a metal support that goes across the the middle of the cart underneath the seats and it seemed to protect the solenoid and the relay switch along with have wires attached underneath, well i forgot to secure the metal piece and while driving it i heard a pop and the cart stopped. I lifted the seat and noticed the metal support had touched 2 posts on the solenoid and arched( i think). Replaced the solenoid and still nothing... is there a fuse somewhere else? Your Thoughts please..
