Question for the group on panel dimming. I've got 4 dimmers total, 3 PWM units for LEDs in switches, map lights and cabin lights and an empty hole for a simple pot to provide an analog voltage reference to a common lighting bus for the 3GX and all the other Garmin stuff. The reason for the empty hole is I can't figure out what value pot I need for the lighting bus, given that the Garmin units only use the bus voltage as a reference for their internally driven backlighting, ie they don't draw any real current from the lighting bus... What have others done?
