Disconnected charger interlock at the bullet connector, still nothing. 🤦*♂️

So, here is what I found:

1- Key switch is good.
2- F&R Rocker switch is good.
3- Run/Tow switch is good.
4- MCOR (I have a MCOR 4) is good, with consistent continuity over two pin connector when switch activated and ranging between 1100-6800 ohms across white and yellow pins with throttle input.
5- Positive input on solenoid is good at solid blue (50.4V)
6- Negative input on solenoid has been lost.
7- Still no reverse buzzer, blinkers, or brake lights.
8- Tail lights and headlights are okay.
9- All fuses are good! 😁🤙🏼

I’m thinking all of this points to controller?

They check out but that does not mean the controller is receiving them. Try these checks. I use these on IQ carts. (One wheel jacked up) Get your DVM and place the Black probe on the pack Neg and then with the key On, cart in Fwd, and Go Pedal depressed far enough to hear the microswitch click, take the Red probe and check to see if you have pack voltage in the following pins at the controller: Pin 5 - Lgt Blue must be >30v (you have an ERIC so may be different), Pin 6 - Green, Pin 8 - Brown, Pin 9 - Grey, and Pin 10 - Tan. To test the Throttle signal, got your VOM and place the Black probe on the pack negative battery post. Put the Red probe on Pin 2 - Yellow wire. The voltage should range from around ~0.3vdc pedal Up to ~4.65v or more with the pedal all the way Down.

If you have all the required inputs met, then you have lost an FET in the controller and will need to upgrade to a new Alltrax or try and rebuild yours. https://www.revolutiongolfcars.com/a...ct-controllers the 300 is a direct replacement and upgrade to your OEM

All other voltages check out.

However, I’m reading 0v on the yellow. This is both at the harness as well as at the MCOR actual.
