Hello guys,
Silly question:
I'm about to install the Stall Warner vane assembly. It is basically the first electrical item in the build that requires direct ground connection to the structure of the airplane.
Step 7 found in OP46-04 says "NOTE: Make sure to remove primer or paint that would prevent the ring terminal from making a ground connection to the mount bracket. [....] Attach the Ground Wire to the N.O. (Normally open) terminal on the ES E22-50K Micro Switch".
It is pretty straightforward, but my silly question is: because this part has to make solid ground, is it advisable to also leave the line of rivets that attaches the VA-195G (or VA-195G) Mount Bracket flange to the inside of the Leading Edge skin without primer so that metal-to-metal contact is achieved?
This because I've primed every single rib, including both sides of the flanges and all of the inside faces of the skins in the whole project so far (empennage and wings), thus they basically make primer-to-primer contact.
Am I overthinking this, or do I better start scraping some primer off before closing the wings?
Will this same principle also apply for NAV lights, strobes (specially strobes to avoid noise), landing/taxi lights, antenna, etc. in the future?
Or do the rivets make full metal-to-metal contact when they are set?
what say you?
thanks
