EZGO works one day, and doesn't the next

[XCOP1152]

We have an older EZGO txt. I think it's a 2000 model. When it runs it runs great, but lately it has started intermittently not working.

Yesterday morning I turned the key and it worked great, drove around the yard, and parked it. Yesterday afternoon I turned the key, hit the pedal, and nothing at all.

This happens everyday. It will work one day, and not the next, and then it starts working again for seemingly no reason. Nothing seems to be happening to cause it to work or not work.

We have checked the key switch, and the accelerator box under the floor panel. The batteries are fine. All connections have been cleaned and tightened.

This is frustrating.

Can anyone point me in the right direction or give me some advice? Thank you.

Check the condition of the wiring and plug between the 6 pin plug on top of the controller and the pedal box. Usually there is a four pin in-line Molex connector located in the battery compartment between the bottom front center and the controller. Moisture and/or corrosion in this connector can cause strange symptoms. Next time it won't run wiggle these connectors.

Thank you. I plan on eliminating that Molex connector (as has been suggested here) this evening or tomorrow morning. I will inspect the wiring at this time also, and post here.

Should I perform the troubleshooting steps listed in the chapterE.pdf suggested in various places on this site or could this be something more simple?

Everything in your pix looks very dirty. I would clean everything up and check all connections. You have a bad connection somewhere if it sometimes works and sometimes doesn't.

I will get the wiring cleaned up this evening or in the morning (it has been super hot and humid here lately, waiting for a cooler evening).

Thanks!

I would think warn brushes cause this too. But the connections RadioMan and VA mentioned are what I'd look at first.

Thanks for the info. This is something I had not considered. I will look into checking the brushes also.

In pix 5 the troublesome in-line Molex connector between the pedal box and controller is shown. You need to make some voltage checks. Most of the wiring you need to access to narrow down the area of trouble is in pix 5 in your post #1. When you press the pedal and the cart don't move do you hear the solenoid click?

First thing I always do when a cart won't go is take apart the molex connections and spray every connection on both sides with electrical cleaner. I would say that 90% of the time that makes it go again. One of my carts will sometimes sit for 3 weeks and then it might not go when I try it. Cleaning those connections has fixed it every time so far.

If you don't have a spray can of electrical cleaner, I would go to an auto parts store and buy some, then use it as part of your monthly maintenance when you check the batteries. Good luck with it

I do have a can of spray cleaner, but would it be better to eliminate that connector and replace it with butt-splices? I have seen this mentioned on this site numerous times.

Thank you.
