RXV Auto-Brake Problem III

[cartboy]

Well, it's been almost a year since:

http://www.buggiesgonewild.com/elect...e-problem.html

We have one cart that has the auto-brake lockup problem, and it just started doing it.

It either did not get the new solenoid (EZGo did not give us records of the ones they replaced), or a new, replacement solenoid is failing. Based on the cart #, I'm leaning toward the former, that it still has the original solenoid.

In your previous topic you said that.... now you are saying that there were some that were not replaced?

I assume you have already turned in a request for service to your local Branch/Dealership ? Can you please take a pic of the solenoid on the failed cart BEFORE they change the solenoid as well as a pic of it AFTER they change the solenoid?

Another one has locked up, and, again, a cart # that suggests it might not have gotten the replacement solenoid.

Our dealer (not the EZ Go rep) was by and confirmed that both carts have the original one. He is to be back this week and put new ones in, so I don't know if I will get pics or not (I'm off tomorrow).

In talking to him, others have not had the problem, and we think it is because we have a very hilly course. & maybe heat is a factor.

If heat is a factor, there will be failures in Florida, Texas, Arizona, California, etc.

Actually I called in some favors to talk to people about this issue and I learned a few interesting things regarding the RXV.....

Yes, there is an issue with the RXV solenoids, but changing them out does seem to correct that issue.

There is also another issue related to the original RXV's that were released whereby the lights (factory installed to draw from 1 battery) can actually cause the cart to stop dead. It has something to do with the RXV Controller being hyper sensitive to the total pack voltage and when the lights are left on (or just used ALOT) they tend to kill that 1 battery and cause all kinds of havoc with the running of the cart.... This seems to have been resolved in later models where E-Z-GO now installs a voltage reducer that draws from the total pack.... Actually a really nice reducer if you ask me...

Also (and this one is REALLY important for used cart dealers as well as private owners), when E-Z-GO designed the software for this controller, they did so with Golf Courses in mind. What this means to the private user is that the cart was designed to basically shut down after about 12 miles worth of running. Considering the AC motor in this cart should do at least 30-40 miles on a charge, this is a huge OOPS on E-Z-GO's part (The Villages is the largest Golf Car Community in the world and those folks are spitting mad over this one....). On the good side, E-Z-GO has rewrote the software for the RXV for use in the private field, on the downside, you have to get a RXV MASTER TECH to install the software update (or have access to one of their diagnostic handheld tools and a VERY good friend that works for the company and is willing to get you the updated software).

There is a current thread on the Talk of the Villages forum started by charliev where it appears he has the upgrade but is still having problems. I posted there, to tell them about this discussion here, and got booted.

I realize internet forum administrators are suspicious and protective, especially of first posts. It's a shame though, since I've been working with a fleet for two years, and might have been able to share some things with cart owners in The Villages.

I guess they won't miss what they don't know they're missing.

I did manage to get a PM and link to this thread to charliev.

I'll post a link to that thread here, if it's OK.

I played golf at my course yesterday and there was a cart from the day before abandoned on the course. I brought it in. When they die like that, if you switch the key off and back on, they will go again for awhile. When they hit limp mode, you can switch it off and back on again and go awhile again.

I'm confused.

Your comments here, and throughout this thread, do not seem to jive with your Post #3 here:

http://www.buggiesgonewild.com/elect...-ezgo-rxv.html

We continued to have assorted problems for the duration of this season, most electrical. Most seriously . . . carts dying on the course, excessive battery terminal and connector corrosion, failure to accept a charge, and a resumption of the solenoid failures.

As of the end of my season, our dealer had not installed the software upgrade yet, and carts have still been dying.

Have you not experienced any of that?

[cartboy]

I played golf again today. Sweet . . . in December.

More carts up against the wall, out of service. Notes indicated electrical problems.

Some talk about getting rid of em.

Golf was good, as it normally is when it doesn't count and you're playing alone.

I guess all the bad RXVs got sent to us, and no one else, anyway, got one.
