Rather than checking voltages on the dimmer rheostat, start with checking them at the connectors on the cluster.

Specifically, on the right side connector, check the black wire on the top right for 12 V (the brown on the bottom left is ground).

Also check the blue next to the black for 12 V as well.

Also, measure the voltage on the grey and yellow wires with the headlight switch both on and off. Those two wires are the input to the cluster from the dimmer rheostat.
