I also know that during the latest refresher course I took for the RXV, we were told that trying to circumvent the reverse buzzer would disable the cart.

I will agree on the liability suit if the buzzer was disabled and returned to the owner.I would assume they have a way to silence the buzzer but not disable it,maybe cover it with tape.
I have also heard that disabling the buzzer,unplugging it,would disable the cart. My cart has a cotton ball in the buzzer speaker hole and tape over that.I'm deaf in that range and can't hear it anyway but everybody else could so it's fixed.

Seems EZGO did a lot of research on this cart and tried to make it fool proof.

I'm in Costa Rica so no chance of a law suit. But now im wondering how they made the controller not pull low on J2 cuz the buzzer is fine it's the controller.

I called them and they "disabled" it by putting silicone over the speaker part. They just made it quieter.

So the question is the controller bad if its not working on J2? would it pass self check out and then fail after pedal use.

IDK,I think you should call them back and ask them but I know if it doesn't "see" the buzzer it won't go as it's a safety feature.

I think the Curtis control checks the resistance on that line to make sure the buzzer isn't removed. It can in a sense be disabled however, the handset lets you adjust the PWM..so lowering to a point where the voltage is too low to drive it will "disable" it.

Unfortunately this thing doesn't have a diagnostic LED, so you pretty much need a handset to read faults. Id start there if you have one or borrow one if you can though the 1206ACs have some rather bizarre and esoteric fault descriptions.

Here is the fault details for the rev buzzer:

BUZZER DRIVER OFF

Reverse Buzzer
does not turn on

Limp Home +
FwdOnly

Condition clears

1. Buzzer current < 3 mA when driver
commanded ON
2. Incomplete buzzer circuit
3. Verify continuity of reverse buzzer and
replace if open

To recap. The buzzer is connected and is not faulty.

Pin 2 on the Curtis controller is not providing a ground during the startup self check nor when placed in REV.

I guess i need a curtis controller expert...
