Default Re: marathon problems! cart wont move

Welcome to BWG!

I've been deciphering schematics and wiring diagrams for 50+ years and I tend to agree with your suggestions concerning the designers of the resistor carts, but it would be a waste of good lead and feces.

Here are the best drawings I've found. They are both electrically the same, but the first shows the switches more clearly and the second shows the battery layout better.

Both diagrams are complete and your cart will run if wired as shown.

The third drawing has the solenoid activation circuit traced.
Heavy lines are high current cables (6Ga or heavier)
Lighter lines are control wires (18 Ga)
Red is positive.
Blue is negative.

I'm guessing the solenoid isn't clicking, so that is the first problem that has to be fixed.

What is your battery pack voltage? Ought to be 38.2V for a fully charged pack.
