Newbie with Marathon troubles

I've been on the forum for a while, but now I really need some help. Couldn't really find an answer when I searched for my problem. I have an '89 Marathon I got last fall. This summer it just quit on me. I replaced the solenoid, resistor coil, and wiper board. Cart started working. So I loaded it on the trailer and charged the cart. Got to the farm the next day to ride, and it wouldn't move. When I press the pedal, the solenoid sounds like it is constantly clicking, but the tires won't move. I tested all of my batteries and found out one is bad. Should be able to replace it this pay day.

Two questions:
1. Any idea what the clicking noise is?
2. Should there still be enough voltage to make the tires turn while on blocks?

Thanks,
Robbie
