Yamaha Quietech Stopped Moving
 

Have a 2017 Yamaha and has been running fine, no issues. Backed out of garage today, Put in F to turn and drive away. Went enough to turn but stopped and end of driveway and would not move, forward or reverse. Any experience of a similar problem and what the cause was?

Battery died?

Bad ground wire would be the first thing to check. Poorly crimped wires can become loose over time. I doubt it’s the battery if the cart backed up no problem and then suddenly died?

BAD solenoid.... easy and inexpensive fix..

Recheck that the lever is set in F

Does it make any sound even though it does not move? Do any of the electronics (speedometer, lights, horn, etc) work when the key is turned on?

If it went forward enough to turn then I assume the engine was running at the time. If it stopped moving while the engine was running then the best you could hope for is a broken drive belt. This is something that should be pretty obvious if you lift the seat.

Another, less likely, possibility is a broken starter belt. You might hear the starter motor (generator) whirring when you press the pedal but it could be too quiet to hear. Again, if you lift the seat you would see the broken belt or at least the empty pulleys where a belt should be.

If it isn't one of those two easy problems then it could be any number of things like a blown fuse, a bad starter motor, a bad ground or other loose connection, etc. Others might have things to look into but it could be time to call a repairman.

If your battery is over 3-4 years old, it could still be the battery. I had a gas cart years ago that did exactly what you're saying. New battery fixed it.
The other first thing that you can check is a blown fuse.
Otherwise get a cart tech out to diagnose.

Dead battery my guess, but why guess?

Take the guess out of batteries and get one of these. ANCEL BTS200 battery analyzer. It will tell the condition of the battery you don’t have to mechanical have knowledge it tells you if it good or bad.

Amazon.com: ANCEL BST200 Battery Tester 12V Automotive, Car Battery Tester 100-1100 CCA Battery Load Tester Tool Digital Analyzer for Car Truck Motorcycle SUV Boat and More : Automotive

Or similar and shop around can be as low as 30 bucks.

Takes all the guessing out of condition of battery.

Call Todd Casey. He'll come to your house and fix it.

Broken cable from gas pedal to drive.

Most likely a dead battery.

I just had something similar happen, the secondary clutch failed, there was a clunk and then I was in limp mode. Depending on the failure I could see the cart failing to move. In this case the engine was able to run the cart would barely move. If your engine stopped and would not start again, then I would be looking for a blown fuse. NOTE: there is a 25 amp fuse on the NEGATIVE side of the battery that kills everything. While I have not experienced it, I am guessing a cable failure in the forward/reverse control could cause this type problem.
I would need more info on what exactly happened.

You didn’t say if the motor shut down and wouldn’t move or just died and wouldn’t restart. If the motor is still running then you have a transmission problem

Does the engine run?

If so - look too the secondary clutch or (hopefully) the drive belt.
Replacing drive belt is a (relatively) easy/quick job.

Battery
 

This happens to me sometimes. I pull up the seat and loosen and tighten the battery connection cable and it starts working again.

First things first. Are your lights working? If not likely a blown fuse. If they are working always go to the battery. The only way to tell is a load test to determine if the battery has the amps to turn it over. After that it could be foot pedal switch, solenoid, or a couple of other items. I always go to the battery first. Even if your lights working it doesn’t mean the battery is good. Quietechs are notorious about killing batteries because of the heat that gets trapped in the engine bay.

And if he gets it fixed quick enough, he and his kids will get out of dodge just in time to avoid the heat ray!!

Trivia Thursday: name the movie

Happened to me. Battery dead

Call Scott Jezowski 352-348-7381. He is mobile and reasonable.

Do a search on You Tube!

Battery cut off
 

Mine did this and it was cutt off knob ob battry cable, it was coming loose. Mine has a green knob to tighten

I had the same problem. It turned out to be that a wire connection to the solenoid came loose. Simple fix.

I wish the poster would get back and tell us what fixed this issue.

Our 2017 had a secondary clutch go out.

Sorry for the delay. Thanks for all the suggestions. Lights did come on. It was not in neutral; it was either in F or R. You would push the gas while in either and nothing...no engine sound or anything.

Had repair technician come by today. It was a bad battery. Replaced and running great!

Again - thanks for all the ideas and suggestions. Much appreciated.

first step
 

lift seat and look for obvious mechanical problems.
last time something like this happened to me, it was wire at the base of the shifting laver (F or R) had broken. It was easy to see. Hope it is for you as well. Good luck.

There is a Yamaha fuel display on Quietech in the center of the front panel. At the top there is a little icon which flashes or stays red if you do not have enough charge/oil. If I see this come on, I don’t stop driving the cart until it goes off. I also read the voltage on the aftermarket speedo TV Golf Carts put on by the steering wheel. Sort of like watching your fuel level.

Just got one of these, then I checked the battery and it tested “good”. Thank you for this suggestion, saved me from having to buy a new battery. The aftermarket speedometer seems to be the culprit in draining my battery. So when I get to it, I’ll have it rewired.

What should the voltage be on the aftermarket speedometer display?

To get an accurate reading this should be connected to the battery on dedicated circuit, with a relay to shut it off. I mention this because some of the Yamaha golf carts have a wiring harness that has a 2 volt or more drop to the dash wiring, so if you connect it in the dash your reading will be off. NOTE: this voltage drop is the reason for the battery overcharging, see my post in the DIY and Golf cart areas.
