Installing the crack upgrade.

The small circuit board was installed and passed all voltage checks.

The larger circuit board is not showing any resistance readings between 12U and OA, and between 12U and OB.

I've attached some images of the top and bottom of the board. Appreciate any troubleshooting tips.

Zero. Tried adjusting the scale across options as well.

OK, zero is zero and OL means "Over limit" which is what the manual specifies as a correct reading.
