The circuit breaker for the nav lights on my '86 CVX18 is acting up and being 38 years old it's time for a replacement. As long as I'm doing one I might as well replace all 6 of them. I can read the rating on all but the breaker for the ignition. Any thoughts on what that may be, 20, 25 amps? If you happen to be looking under your dash at the breakers the ID tag is on the starboard side. It's a paper tag so by now they might be a bit faded. I've looked at several the schematics in several Glastron manuals and can see the breaker for the ign. but no values are listed. Any help is appreciated.
