Rick,
Glad that your circuit breaker assembly showed up in such good shape. I will offer my two cents worth, but recognize that my electrical knowledge is even more limited.
The schematics for the Lynx 11 show only one connection on the right hand side of the circuit, and that is for wire 20, which is for the temperature gauge. And that connection appears to be to the second terminal from the top. For the mounting bolt on the upper right hand corner, I simply started it under the top plate, avoiding any short circuit possibility.
I was going to wait until I had the opportunity to visit and view the Lynx 11 at the Canadian War Museum and confirm my assumption. Also hoping that Rob Love may pipe up and offer his thoughts based on his knowledge and access to the Lynx in Shilo.
Glad that you spoke up, my assumptions are just that, assumptions.
Peter
