Thanks Johnny! I'm in the process of gathering supplies for the re wire.
I do have a question though....

I'm the schematics, there are wires that come off in some instances that show an arrow and a single non boxed letter. Not the boxed double letters designated in the key.

For example, there is a 12 ga red wire coming off the 10 ga red wire going to the isolator from the generator.
This wire goes to X.

There is also a 16 ga org dbl blk wire coming off the front switch, going to R.

What am I missing?
