Default 2008 RXV Won't move, No clicks!

Looking for help just like everybody else! LOL

OK 2008 ezgo rxv! Working fine and then all of the sudden dead! Nothing! I get no clicks when I put the key in R, N or F. I push on the pedal and no clicks either. Been reading forum for days now hoping to cross someone with the same troubles. No real luck. I have changed the key switch, checked the fuse, tested the run/tow switch, changed the solenoid and still nothing. Pack voltage is at 53.4 volts. The wire at the charge port is at 32 volts. All connections are clean and corrosion free. The only way the cart will move is by releasing the brake lever. I have pulled up on the throttle pedal and checked it with no luck. What common things have I missed if any? What might I do next? Thanks for any help on this.

Update, 1.2 volts on the wire plug on the brake with run/tow switch in any position with key switch in N. 27 ohms resistance on the brake itself. No clicks of any kind has me confused and concerned. Please help!

Use search button above, and search "Danaher Rxv troubleshooting guide". Download it, It has tons of specs for you to check. It does lean pretty heavily on having the handheld scanner, but a little "reading between the lines" and looking at the pics will help even more.

Is there a common factor that would cause nothing to happen? No sounds, No clicks, No signs of anything. Should I go to the connector and start checking voltages to see if the controller is bad first?

With these RXV's you need to know what your do or you got a good chance of blowing the controller. Do some reading get to know what your checking touching the wrong to wires and you'll be buying a new controller$$$.

This is a summary of the RXV power up test. I copied this from a member but can't remember who exactly. Probably cgtech, usgicollector, bob boyce or hightech red neck
Quote:
The RXV golf carts are some of the most sophisticated carts in existence. One of the things that many people don't know about with the RXV is that they have what is called a "power-up sequence." During this sequence a number of checks are made, and if any of them fail the vehicle will not run.

Here is the list of things the RXV self-checks for:

Electric brake - it will attempt to rock the motor a 1/4 turn both ways.

Park brake check - it will engage and then disengage the electric brake to check parking brake function.

Reverse alarm check - it will beep the reverse buzzer. (Yes this means if you remove or disconnect the reverse buzzer on an RXV the cart will fail to run.)

Charger inhibit check - Checks to make sure the charger is not currently plugged into the cart.

Throttle switch check - Also called HPD or high pedal disable. Accelerator must not be pressed or the cart will not run.

Throttle operation check - The cart makes sure the pedal registers both fully closed and fully open voltages correctly.

Any of these checks not passing will cause the cart to not run. Unfortunately, not even a handheld scanner can tell you which condition failed. I will give you a list of the common reasons I have seen for RXV's to fail the checks:

Bad charger receptacle port: Makes the cart think it's charging when it's not. Sometimes even a wet receptacle on a recently washed cart will trigger this.

Disconnected or removed reverse buzzer, or a buzzer full of water.

Accelerator is remaining partially depressed due to debris, mud, or some other factor preventing the pedal from returning fully. You can catch this one by reaching down and pulling the accelerator pedal all the way towards the seat and then switching on the cart. If it runs when it previously did not, very possibly something is causing the pedal to get stuck.

Loose battery connections. Especially on the RXV's with four twelve volt batteries, the rear battery tends to have a bad connection on the driver's side post. Check all the battery cables.

The aforementioned faulty solenoid. Inspect and replace. You can usually see an indicator of a bad solenoid because of a clear difference in color between the main posts, or even black marks or other signs of scorching.

The connector under the cupholders being loose or missing or damaged. Underneath the center of the dash there is a big white nine pin connector. Make sure it's not wet or damaged, and it is securely plugged in. Can cause carts to fail to run.

Faulty run/tow switch. When a run/tow switch starts to get weak or corroded it can cause failures to run because the vehicle essentially thinks it is still in TOW mode. Check the switch for signs of corrosion, damage, or loose wires.

My experience:

The local shops where I am ask customers to make sure the pedals are fully up and the tow switch is in run before they come to get the cart. Also to check the fuse on the blue wire coming out of the charge receptacle. Cart won't run if it gets wet. In most cases its the pedals. Usually fixed over the phone.

The electrically activated mechanical parking brake on the end of the motor is also a common cause of the cart failing to run.

Also, since this is a 2008 cart the original parking brake and solenoid were problematic. If these are original I think you should change them no matter what.

Okay! I have the troubleshooting guide now and what was just posted on the startup checklist! Since the last update I have now checked the brake switch and accelerator switch and both check out fine, also I have checked the charge port and it checks out OK too. The overheat sensor on the controller ohms out good too! I have not checked the accelerator sensor or the brake sensor yet due to not having piercing leads for my meter. When I look at the guide and it says it checks the brake first when the key is turned on! Mine does nothing! No sounds, no clicks. Nothing that I can hear anyway. SO IS IT FAILING THE BRAKE TEST AND SHUTTING EVERYTHING DOWN? ONCE IT CHECKS THE BRAKE AND THEN NOTHING! There is very little voltage on the wire going into the brake, maybe 1 plus volt. No matter the position of the key switch or run/tow switch, but the brake ohm out at 27 ohms. Could that be a controller issue? Thanks again for your help.

If your only getting 1 volt to the brake you could have an controller issue. Should be close to pack voltage at first on activation.

Do some more testing or get a handheld programmer on it.

Summary:
Pack Voltage - 53 volts
Charge port - checks good with voltage top and bottom right
Charge port wire - has voltage fuse is good
Connections all good on all batteries
Solenoid - new and working
Key switch - new and working
Brake pedal switch - checks good
Brake sensor - within range
Acc pedal switch - checks good
Acc pedal sensor - within range
Fuses - good
Brake - within range (ohms)
Overheat sensor - within range
Run/Tow switch - checks good
Connector under drink holder - checks good
Head light, tail lights - working
1 plus volt at brake plug in any position on key switch except off, any position of run/tow switch
Motor - checks good no resistance on the leads

I don't know what to try next! Still no clicks just dead!
Do I need to check voltage on brake plug while turning on the key?
Do I need to check pin outs on the controller plug?
Can I check the controller without a programmer?

Yes check at the plug. Where and when are you just getting 1 volt?
