My diagram for the 52 shows the A bus powering  blowers, nav lighting  and horn; B bus powering wipers, windshield vent and panel lights; C bus powering cablemaster, helm air, courtesy lights, engine room lights and a few other things specific to the 52. May or may not be similar to your Coronet. I can usually locate circuits not listed in the diagram by looking at the back of the helm circuit breaker panel. It's not difficult to see which breakers are connected to which feed wires.

Drop Tiara a note with your HIN and they will send you the wiring schematic. Very helpful to have.

Same boat Coronet 2013.  My Helm C seems to have shorted out from something. White toggle switch now sticks out a bit from the rest and probably needs replacement. Any ideas? Also need to figure out what caused the problem
