RXV/Danaher won't move.

[SloS13]

I recently purchased a used RXV with Dahaher controller. I decided to fix the horn which led me in to the cupholder wiring mess. I tried some things and failed, so I put everything back like I had it. Now the cart won't move.

Healthy pack at 51v

Here's how it's acting:

Turn key from OFF to R: 2 solenoid clicks, constant buzzer. Accelerator does nothing.

Turn key from OFF to N: 2 solenoid clicks, no buzzer self-test, accelerator does nothing.

Turn key from OFF to D: 2 solenoid clicks, no buzzer self-test, accelerator does nothing.

Turn key from OFF to D while holding accelerator: 2 solenoid clicks and buzzer self-test. After letting off the accelerator, accelerator does nothing.

Turn key from OFF to (ANY) + tow mode = brake disengages.

Cart has a nice 12v box so I removed the fuses from that to limit the number of variables, but made no change other than 12v accessories no longer working of course.

I don't know if I broke something while I was trying to get the horn to work or not. I'm not a master electrician but not a complete noob either. The fact that I can get tow mode to work tells me that the brake is functioning, but I'm no expert with these things so I can't say that for sure.

I want to upgrade to a Navitas TAC2.0 and don't know if that'll fix or exacerbate my issues.

Any help would be greatly appreciated. I printed out the Danaher service manual and will try to work through what I can with that.

Also, I tested continuity with the "run jumper" connector in the bottom of the cupholder and the 2 circuits are completed. Cart acts exactly the same if the jumper connector is connected or not.

Did the cart ran before working on it? Follow the Danaher Guide and be careful when working on the harness, the RXV is pretty sensitive. What is a 12v box, a reducer?


Understanding the Power-up Sequence
• The car will perform the following checks during the first
second of initial key – on.
• Electric brake check – Controller tries to rotate the motor
¼ turn in both directions.
• Park brake check – Controller disengages and reengages
the park brake.
• Reverse alarm check – Controller sounds the alarm for
100ms.
• Charger inhibit check – Controller checks the charge
receptacle for connection to the charger.
• Throttle switch check – Throttle switch must be open to
pass the start up test.
• Throttle position sensor – Controller checks the TPS for 0%
throttle. .38-.56 volt
• Throttle operation check – Controller checks the TPS for the
correct open and closed range. .5-4.8v
The car will not run if the controller detects a problem
with any of the circuits above.

Yes, forgot to mention. Car ran great before. 12v box is a Pro-Fit DC to DC Converter

Extreme caution should be used when working on the RXV wiring. A quick short trying to read a voltage can damage the controller. What happens if you pull both pedals back towards the seat and then turn the key to forward ? Are the clicks happening quickly or about 3-4 seconds after turning the key ?

What does the timing of the clicks typically indicate?

If I understand the question correctly, it's the self-test sequence of the controller. This thread is old but as cartdoc1969 suggested, I most likely killed the Danaher by probing with a multimeter which is just really sad for all parties involved.

I put a 600A Navitas in there and going well over 30mph so I'm good.

I also went with the Navitas 600 amp controller. Went from 21/22mph to 37/38mph. Pretty crazy of a speed jump.

As for your issue, I would look under the dash and sort that out. If it ran before and the only thing you did was under the hood then it might be a wire issue.

One thing I found on my 09 model RXV. I went thru the troubleshooting procedure. The very lasy test was to test brake for voltage with the key on. I had not voltage at the brake. But ,when I wiggled the harness at the brake pedal switch, I could get it to work. Replaced switch, and that fixed it. I bought it used from a guy who said it needed a controller. He did not go completely thru the troubleshooting tree. I paid $2k for my cart,and got it going by following tje service manual to a tee. Hope this helps.

where can you download the service manual? i have a 2011 i am trying to diag
