This is for the experts,I can't find a reason for it?Cart is a 2000 regen,new solenoid,controller,motor,4ga cables,ignition sw,and harness.If the cart sits with tow/run sw in tow or if batteries are disconnected for any reason I no longer have solenoid activation,circut is dead.Jump power to it and the batt light will come on briefly and the circut is back.As long as power is kept on the cart it won't happen again.Oh forgot,OBC is also new.Just wondered if anyone had ideas,I certainly can deal with it but one of those things that bugs me..Thanx Dave
