RXV Curtis Controller won't move

[cartdoc1969]

The controller will check the reverse buzzer during the startup tests. It's one of the last tests in the sequence and will not pass if it doesn't see it. I believe on the Curtis units the reverse buzzer can be turned off in the settings. You'll need to get the connection clean enough so the handheld can communicate with the controller. I would take a close look at the wiring harness for corrosion or poor connections. Check the run plug under the cup holder, it's a common failure point.

I've checked the run port underneath the cup holder. Does have a little green corrosion film. Sprayed contact cleaner and plugged and unplugged a few times.
Got the programmer plug pretty clean. Can get the power light and rx light to illuminate on the Curtis computer USB. Still will come connect. It's powering up and going through the test, but will not move. Reverse buzzer works. Good battery voltage. I just don't know where to look on these carts. A TXT I could fix with no problem. Just haven't worked on many of these. I hate to throw parts at it. I'm wondering if it's the controller being that it will not connect?

Anyone? I know there are some good RXV guys on here!

First have you ever used this programming station before?

Do you have the software to run this in your laptop computer?

If so, I would say it's not communicating with your laptop.

Something wrong with the EZGO cable or pins.

Oh yes, used it all the time on Club Cars and TXT 48. I just don't know anything about these RXV carts! Glad you pooped on here! From some of the other post I've read, you seem to be pretty knowledgeable about these.
I just don't want to go throwing parts like controllers at it, and cost me and the customer a pile of money. Other than the brake, that's as far as my diagnostic abilities go with these things as far as a volt meter is concerned. Coil ohms are around 27, cart doesn't lunge anymore during the test. There was some slight wear on the shaft where the brake mounts, just kinda shiny. Have no clue where to start checking three wiring harness for corrosion, or anything like that. So far all looks good. It's a good looking cart that has been kept inside. 2012 model.
Thanks for the reply!

For right now you need to find out why it's not communicating with the controller. Plug the programming station into something else just to make sure it is working just to eliminate that possibility. You could have something wrong with the plug or worst scenario the controller is gone.

Yep, that is where I'm stuck at. The EZGO pin on the cart side was corroded pretty bad. Cleaned it with contact cleaner and got it fairly decent looking, but still no luck. Any other controller I could go directly to the molex connector, but not these I guess. I guess I need to find another connector for the cart side and splice it in and try that first, unless you have anything better to try?

I have used the programmer on a Club Car since with a different adapter. I guess I could ohm each pin in the ezgo to see if there is any open pins in it. I'm not at it right now, but I'll check that.

These controllers do use the same software as the DC Curtis controllers? Correct?
