Thanks for the information

Should have checked that out before buying a 1205 controller.
Unless there is a "ET" suffix in the part number, it uses a Pot-box.

Mr JohnnieB
Your right I should have looked a little closer,before buying this controller.
Now that being said,from all the information I have gathered, the curtis 1205-210 will work on the series ez go cart. My only concern is the control wiring. From the picture I saw,it only has 3 terminals where my alltrax has 4. Now, I'm speaking of the small wires on the controller.
If anyone has an answer to this please let me know.

Thanks

Sorry, that might not have come across quite the way I meant it. (I forgot to include a at the end)
Please disregard the first sentence, the second one has got the pertinent information.


Here is the Curtis 1204/1205 manual. Check out the paragraph titled "Electronic Throttle Wiring" on page 16.

In a nutshell, unless the controller has the optional 0-5V throttle input, it only uses a pot-box type throttle.

As for the 3 control wires vs 4 control wires, it will work.
The orange wire from MS-4 is for 1/2 speed reverse with the stock series (Curtis 1206) controller and the Alltrax replacement for it.

Well everyone,I got my curtis controller put in my cart and It did work,Well some what. Now please take into consideration I am not the sharps tool in the box.So here is my quandary,the cart will run in both direction,Just not when the F&R is in the right position.
Now for my questions about these controllers. This controller has 4 control wiring spades,3 close together and one off by it's self next to the A2 bar.
do you have to use this other spade??? and as of this writing I have not hooked up to the A2 bar.Do I need to use this bar? If so,no problem,but can anyone tell me why this bar is used on some controller and not on others.
and JohnnB,I got a large laugh out of your comment. That's what I was thinking after the fact.(impulse buying)

Thanks to all
Sonny

Different controller, but the attached shows how to wire if you don't have the A2.

My understanding is that A2 is used for plug braking and/or regenerative braking. I believe plug braking is used on forklifts, where you can slam it into reverse while going forward, or vise versa. Regenerative braking is simply using the motor as a generator to charge batteries.

My neighbor's buggy has a "feature" that prevents him from free-wheeling down hills.

I'm not a believer of regen braking, at least with the kind of riding I do. If you are out riding around the 'hood, and have an equal amount of uphill and down hill, you are far better free wheeling downhill, in order to have enough speed to coast partway up the next hill. Gravity is recoverable, with only wind and rolling resistance working against you. A regen system will only capture a fraction of the potential energy you have once you start going down hill.

Thanks for the fast reply.Since I have the A2 on this controller,I will hook it up that way.Now, what about the control spade(small wire) next to the A2 bar. Should I just leave it alone or put some wire to it??

Thanks again

If you want cart to run at half speed in Reverse, connect it. Otherwise, leave it off.

Thanks JohnnieB
That might be a good thing for safety. Will that be the orange wire?

Thanks

I have a problem with my controller, I think, I can place the shifter in the forward position and the cart runs in reverse,then place it in reverse and it will run forwards. I have changed the black and white wires with no results.Same thing.
Can anyone shed some light on this problem???

Thanks
