Ezgo rxv
I am working with an EZGO RXV with the Danaher controller. When the cart is in the run position it does not pass the all of the initial power on tests. I can hear the solenoid engage but the buzzer does not sound and the brake does not release. The reverse buzzer does sound when the key switch is in the reverse position. When the cart is in TOW mode, and you turn the switch to the on position, I can hear the buzzer sound and the motor rocks and also the brake does release. I don't have the handheld diagnostic tool. What are some things that I can check with a DVOM. Thanks!

Re: EZGO RXV Help Needed!
What pins on the key switch need to have continuity when the switch is in the F position? There is a discrepancy in the troubleshooting guide I think.

Re: EZGO RXV Help Needed!
1. Remove the key switch
and turn the key to the forward position. Place pos. meter probe A on the A pin of the switch. Place the neg. meter probe B on the C pin. Full continuity should be observed on the multi-meter. Go to step 2. 2. Now place the neg. meter probe B on the D pin of the switch. The meter should now read full continuity with the key turned in the opposite direction. If continuity can be read on all three pins in the same key direction (Forward), then replace the switch. Straight from the guide. |

Re: EZGO RXV Help Needed!
Here is what is confusing. Pin three on the switch harness is a white wire. The guide says that pins 1 and 3 should have continuity in the F position. The white wire, according to the guide, is the 20- 48v input from key switch for reverse not forward. Another observation that I made is that the guide on page 23 step 2 states that I should get 5V on the orange wire (pin 3 on controller harness) and the black wire (pin 4 on the controller harness). When I probe those wires I only get .98 volts. This leads me to believe that the controller is faulty. The guide says that these two wires are outputs. I am assuming that the output is a 5V source from the controller and I am only getting .98 volts.

I checked the throttle sensor but I don't remember if I checked the brake sensor. The throttle sensor had a reading of 14K ohms. So that is a good reading. I will check the encoder per the guide.

Re: Ezgo rxv
All of the 5V components are showing to have 1.01V. I did verify the integrity of the wires in the harness. That points to a problem in the controller correct?

Re: Ezgo rxv
Well by the guide it does. I take it you don't have a spare controller to try?
