This EZGO TXT EX1 is a 2020 model year that has bricked itself due to a faulty ISG module which costs around $500 to replace. It is responsible for the power distribution of the cart to the ignition switch, fuel pump, pedal microswitch and other critical components. Apparently this is a pretty big problem for these EFI Kymco engines, and I would not recommend buying one of these machines because of this.

Efl which means you have to have a special tool to diagnose the system on this engine if you can afford it especially if you are working for a golf cart shop otherwise you do what you can with the tools that you have

Thanks for helping me diagnose the cart I’m working on. This is exactly what’s happening not the exact same cart but when it happens I just plug out the fuse and plug back in and it runs the pump and everything.

To answer your questions at the end of the video, this golf cart is beautiful, it’s comfortable, it has room to haul us and all our stuff around the campground, it goes up and down the mountains here in West Virginia like nobody’s business. I have absolutely ZERO complaints about this cart or its performance other than this 🤬ISG. It’s my first experience with one, all my friends have one but theirs are all electric . I like the idea of gas powered for where we take it and what we use it for. My John Deere dealer uses these to buzz around their lots and they had an opportunity to buy 10 more so they sold me one of them. It’s still pretty new but I’m seeing it’s becoming the Ford 6.4 of the golf cart world.

We've been wanting to look At one of those. Five hundred bucks ain't nothing to overlook Seeing your video really helps out We use these for the tractor shows So thank you so much for exposing these guys Thank you for the video

I work on a golf course that has 9 2020 ex1s in the fleet. From what I have seen, the ISG will almost always fail if the battery dies. We have had 4 dead ISGs and we might have had 2 more fail last week.

The amount of time spent on trying to find the problem can be extremely expensive and requires lots of research, then still a big gamble to buy unit and week later doing the same thing 😢😢😢

If isg controller blows again than your stater needs replacement

[jakecupit]

This is a trash motor. My cart has been in the shop multiple times. Now my warranty is out so I'm screwed.
