Decided to test the starter contactor before drilling mounting holes and found the "I" terminal was connected to the "Battery" terminal. This means it won't work they way I had planned to wire it. And it won't solve the starter back EMF problem that Van's was addressing with their lightweight starter schematic. Shared the information with another builder to verify I wasn't missing something. Ordered a replacement Littlefuse/Cole Hersee from Mouser. This will ensure I get a real Cole Hersee. It's possible that the one I got from Van's wasn't a Cole Hersee.

Proceeded with drilling holes for nutplates to mount the contactors per the Van's drawings. If the contactors don't work they way I expected, I can make minor wiring changes to make it work.

Figured out what spacers I needed to mount the FlyLED's control board and included those on the mouser order.

Worked to add firesleeve (for the firewall feedthroughs), bolts for the contactors and bolts for the cabin heat valve to my aircraft spruce order.

Researched and ordered three different types of stainless steel screen from Amazon to use for the fuel vent lines and cabin vent air inlets. I think I may also need some for other air vents.
