Dave,
I asked you before if you had that panel grounded and you said "YES". The switch is mounted to the metal panel and should be grounded while testing.
Here are the voltages: USING A TEST LIGHT
1. Park/off, BLUE and PINK are HOT, RED is DIM.
2. Low Speed, PINK and BROWN/WH are HOT, RED glows a little BRIGHTER THAN DIM when flipped on.
3. High Speed, PINK and BROWN/WH are HOT, RED glows at full brightness. same as Pink and Brown/wh.
I don't see a red wire in your pics, Follow my pics and you should be good to go.
***********DON'T FORGET TO ALWAYS PUT IN THE LOWER LEFT SCREW ON THE SWITCH PANEL!****
Like you posted above is correct: 1, You don't use a "W" on the switch, although the brown wire is there. 2,The Green wire is never hot.(could be ground)
You need to find the RED wire for F1. Put the BROWN wire into W even though it isn't used.
Tell me if you need the pinouts for the motor and/or the bulkhead connector as I have those but will have to draw them.
