94 DS 36 volt little problem.

[HotChickenStrips]

HI guys and gals, my neighbor bought this little cart for fun, and I've been wanting to help him get it to run properly again, but I need some help with it.

I'm a master auto tech, but never in my life I've worked on one of these anyway, and here's what we got:

Cart would move ocasionally, I could hear the solenoid click everytime the pedal got pressed, but 9 out of 10 times it would not move, I traced it down to the contacts inside the solenoid being pretty bad, so what I did was to "rebuild" the solenoid, and I tested it using a car starter and the cart's 36 volts to trip the solenoid and it worked.

But when I installed the solenoid in the cart it was worse than before because now it won't click at all.

I made a little drawing of the solenoid wires position, but I forgot to note the polarity of the diode, so when it failed to click I reversed the solenoid 180 degrees, diode included and still no go.

I then tested the diode and it's not open, but rather "bypassed" so I found a replacement diode (different part number, but according to the manufacturer's
cross reference I got the right one, and I'm going to use the diagram here in another thread to make sure everything is properly wired.

SO my question is, this diode alone would make the solenoid not to work?

Also, is there a way to make the wiring diagram here bigger? when I try to follow a wire, I get cross eyes lol, not to mention I can't really see the color designation either!

Thanks in advance.
