Hi, I'm finishing restoring an old 1977 Carver Ranger and was wondering if someone could help me identify some switches that I have no clue what they are used for. I've asked a few boater and I've tried googling, but I haven't had much luck. I've tried tracing some of the wiring but I believe they terminate somewhere in the 5th dimension. I'm an experienced mechanic but this is my first boat so please pardon my noob ignorance! First, I have no clue what aux volts vs. fuel volts are, what are the appropriate use for each setting? http://s16.postimg.org/tn6044vcl/20140505_154621.jpg Next, I have a push button and 2 rocker switches that are unmarked and I'm at a loss as to what they do. There's also a sliding lever next to the throttle: http://s21.postimg.org/3kojf8r13/20140505_154645.jpg Thanks for any assistance!
