Here are some pics of the track bar set up.








Hope that helps.

Hmmm...interesting...looks like I'll be adding one of these.

Thanks for that

I'm having a new issue now with the motor/cart.

My cart gets up and goes no problem and top speed is MUCH faster than stock.
BUt...when I fully press the throttle pedal down, the motor cuts out (like you let go of the pedal). It's only the last 1/4" of the throttle.......I can visually see the throttle switch and throttle body-thing, because i have no seat...and nothing stops moving.

Any thing I should be checking? I'm stumped. Just want to be able to press the pedal all the way down :(

Sounds like the pot box is dirty or worn. The pot box is a rheostat that gives the controller information about pedal position. I don't remember if the Melex is
0 to 5 ohms or 5 ohms at the off position to 0 ohms full pedal. Pull the wires off of the pot box and using a digital ohm meter check for a smooth and gradual 0 to 5 ohm or 5-0 ohm sweep as you depress the pedal. Try spraying electrical contact cleaner into the pot box while moving the pedal.

Cool build!

Interesting build you have going on here. Sure is low!!

I have a 0 ohm rating at no throttle
7.56k ohm rating at full throttle
5k ohm rating at the sweet spot before the motor cuts out

So....is it fixable
Or do I just get a new one?

The controller is giving max output (or should be) at 5 ohms. You can adjust the linkage to not go beyond 5 ohms and avoid the problem area. I think the area beyond 5 ohms is intermittent and causing the controller to cut power. Curtis Instruments makes a pot box you can fabricate a mount and linkage to replace your current Melex pot box. But it still should only go 0 to 5 ohms. There are import pot boxes that are cheaper. Ck with BWG site sponsors.



Build looks great. You will need a link to keep the rear axle from moving side to side.

Awesome job so far!

Hi, I'm new and loving your build. I wanted to address 1 thing. a triangulated 4 link rear suspension doesn't NEED a panhard bar. You're welcome to install it, but if you notice every picture posted showing panhard bars, none of them are a 4 link like yours. If you had a 2 link, you would need a panhard, but its not 100% needed for your setup, thats why you took the extra steps to weld the tabs on the top and bottom of the rearend.


Cart looks great, you're doing a good job.

looking great! any more progress?
