Txt 48 controller diagnosing

Dan33Klein · 08-22-2018, 08:36 PM

Hey all,
I checked the stickies and it seems there are diagnosing threads on the series and early sepex carts.

Cart is question is a 2012. Brand new batteries and solenoid. I am being told the controller was diagnosed as bad.

How can do tests to determine this myself before a new controller is bought?

If one of the sticky threads included the newer txt48 controllers and I missed it let me know.

Thanks

Hmm, I don't have the "entire library of Ezgo OEM files" on my phone anymore (it died/erased everything). Sounds like I need to renew those files. And I sure wish all the controllers had the "status led" like the 1234/36/38 controllers have. It flashes the error code that you could just look up in the list.

That would sure make it easier.
Another poster posted a wiring harness this morning for a 2010+ txt48 system.
That would at least help somewhat.

I emailed ScottyB to try to get some help with diagnosing. If I can determine it is the controller that is bad I plan on buying an alltrax 500a controller kit from him

The 36V PDS controller (Curtis 1206MX), its predecessor the DCS (1206SX) and the TXT-48 (1206HB) all work the same way. First they have to be powered up. Then they have to be told which direction the amps flow through the field windings, when to activate the solenoid and how many amps the armature will be allowed to draw.

Generic troubleshooting is all that is needed to determine if the problem is internal or external to the controller.

What are the symptoms?

Thanks for repsosnding. I don’t have ge cart in my possession right now but I am hoping to by the end of the weekend and I can report back with the symptoms. Battery back is new and so is solenoid. I will do the basic checks and go from there. If I have good pack voltage and the solenoid is working and shows pack voltage at the controller I will need to diagnose the controller further.

Got the cart today. Was going to start trouble shooting the controller then I noticedt the side of the controller looked a little distorted. I’m pretty sure troubleshooting is a waste of time... lol

Yea, the smoke escaped already. It looks like whatever let out the smoke coated pretty much most of the Logic PCB. A hosedown with Blue Shower might clean the grime off of the logic PCB, but then comes the task of locating and replacing components. You can buy a used replacement 1206HB-5201 from eBay for $215 and free shipping. I bought one from him last week and it checked out to be good.

FSIP would want more than that to repair yours. I could check it out for you if you want.

I just purchased the same one you did. He took 200$ shipped for it.
Hopefully it’s here on wednesday
