Default Re: Problems during solid state conversion

As far as I know that controller does not have a "main welded" circuit detection, so I am not sure how that could have any effect.

Maybe there was a loose wire?

So anyone think I'm onto something?
No it's just going to run a little bit and quit just like on your test ride. Here is a wild guess and it might be worth a try. Nobody has said anything about having a intermittent key sw. Try putting a jumper across the key sw and see if you can have a successful test run.

Wink Re: Problems during solid state conversion

I know I'm getting in late on this but what system and year model stuff did you use to update. The Scotty b number doesn't mean a lot thats his number I would like to see the system what year stuff. That will help and pictures of every thing also would be a big help.
The pre charge stuff want make the cart run are not as stated it keeps the in rush on the contactor from slamming shut on the contacts and helps the life of the contactor.
I have done more conversion than I can remember and most of the time it's trying to make parts out of another cart work with the cart you have to work with!

Andy - visit my website and answer half those questions by reading one page. > http://www.cartsunlimited.net/Scotty...rsion_Kit.html

He is converting a 1992 CC resistor cart to solid state. He is using my C54 kit. 500 FSIP series control. 400 MZJ solenoid, 0-5k potentiometer, HD F&R, & 2g cable set from me. HE is using existing key switch and motor and ? what else. Really the system only requires a few short runs of 14g wire by installer to work. Thank you for your help.

Andy, may I ask why you are using RED fonts?

Indeed, my CartsUnlimited conversion kit went in exactly as described in the instructions. I have had zero issues other than some of my poor wire crimps coming loose over the years.

Just a thought, but since the donor cart was a 1992 CC 36v resistor cart, those carts had a negative key switch and no pre-charge resistor.

Make sure the pre-charge resistor is connected to the big posts and that any existing wiring that was re-used is connected to where You think it should be.

Thank you Beau, that is exactly how the vast majority of these installs go. This control did have a warranty issue which was repaired at the factory. The challenge now is to figure out what is intermittently causing the cart not to run.

Intermittent problems are impossible to locate when the cart runs. Wait until it quits and sort out the problem. There are only a few things that need to work to make this drive system work. The system is as simple as possible.
If the cart runs intermittently it is likely that a loose connection exists. But where?

The solenoid clicks when it does run so I suspect he has made the key switch feed positive? The install diagram shows a constant (-) connection to one solenoid small post. If the key switch signal was also (-) the solenoid would not engage, the control would not power up, & the cart would not run.

My cart is a 90 ccds resistor. I just replaced ALL of the wiring with new when I converted mine. There are so few and it was only a few bucks. Certainly helps to narrow things down when you know all of the jackets are intact and not shorting anywhere.
