Gemini 105Mc Owner’s Manual

Wiring Code
The standard code for 12-volt is red positive and
black negative. Unfortunately the boat cable sup-
plied sometimes comes red and black and some-
times white and black. We have chosen:
BLACK = NEGATIVE
RED OR WHITE = POSITIVE
Note that the color coding is different to shore
power where black is live and white neutral.
The European system is different and electronic
equipment that comes from Europe has the code:
BROWN = POSITIVE
BLUE = NEGATIVE
Switch Panel
The switches on the two 12-volt panels are also
circuit breakers and vary from 5 amp to 20 amp.
See table below.
VHF Radio
The VHF is recessed into the switch panel above the
12-volt panel. Consult the included owner’s manual
for information on operation.

manual for information on operation.
Cabin Lights
The Gemini has three (3) fluorescent lights in the
main cabin over the galley, navigation station, and
saloon table. The fluorescent bulbs take an ex-
tremely low power draw and are intended as task
lighting. Each light draws 1/3 amps. Note that fluo-
rescent lighting is known to sometimes interfere with
VHF reception. Turning off the light corrects VHF
reception issues.
There are also six (6) 12-volt incandescent dome
lights, each located in the head, master bedroom,
each aft cabin, over the refrigerator and in the cock-
pit. Each light draws 1 amps. Red bulbs can be in-
stalled to maintain good night-vision.
Replacing Light Bulbs
Individual bulb specifications are subject to change.
When replacing a bulb, always remember to have the
original bulb with you when buying a replacement.
