Pots on ms3x.
Following directions from aaron. Ive been working on turning the 4 pots. Ive turned counter clockwise for what feels like forever with no click or feel of an indent. Do i need to just keep turning?

The click can be incredibly hard to hear and feel. I think, at least I remember being told this but have not looked it up myself, that the current pots in use have a clutch so that once they are turned to maximum the screw disengages. That's the "click". So you're probably good at this point.
One thing to help hear the click is to put some plastic tube in your ear and place the end of it next to the pot as you turn it. It's amazing what you can hear with a little bit of plastic tube.

Thanks Aaron. Did alot of reading and digging last night and you are correct. All there writing currently states you cant turn them too far. That in mind, do I back them off just alittle from there current positions?

Leave them and see what happens. If you want, you can measure them with an ohmmeter and confirm they are at max value (100K I think for R52, the other one is 10K).

Turn all 4 counter clockwise. Main board and ms3x board. Measure the pots between which polls? I would check now, but board is at work with the car.

Offhand I don't know which pins on the pots to measure.
You can get the schematics for the V3 board at:
