Darn Waffle Zinc!

[Brentathon]

Again this season, my waffle zinc (Alpha) must not have had a good electrical bonding, as it didn't corrode much at all. This is quite frustrating.
All the other zincs are approx 50% smaller, and my trim tab zinc on the anti-ventilation plate was even missing half way through the season (which is another annoyance).
I've been having a real problem getting continuity when installing the waffle zinc, as the femal tapped holes in the hydraulic manifold have some corrosion (Al oxide) that seems to prevent a good connection. I did buy a brass gun barrel brush, and will try to really clean up the tapped holes.
Also, I plan to add even more SS braided bonding wire (like I did for my swim platform supports)....maybe I'll go from the nub zincs on the Gimbal Housing to ring terminals under the heads of the bolts for the waffle zinc. I already added a bunch of SS bonding wires, which seem to have worked well now for the past 6 or 7 seasons (see pic).
