have a 15amp alternator.

Any suggestions?

Hi, Charlie! Get some 1/4" or 3/8" copper tube at your local hardware
store. Flatten it with a hammer, and drill a series of holes in it for
1" #6 or #8 screws. Mount the screws through the holes, using internal
tooth lockwashers under the screw and under the nut. Voila! Busbar! Now
here's something else you can do. Mount two busbars in parallel with a
terminal strip in between. Make the top bus the (+) bus and the bottom
one the (-) bus. From the (+) bus and the terminal strip in the center
between the two busses, run a twisted pair to your circuit breaker.
Then run a twisted pair from the terminal strip and the (-) bus to the
load. All of the load current from the CB to the load will be flowing
in opposite directions in the pair, giving excellent EMI cancellation.
This is especially important in plastic and wood airplanes to minimize
radio interference. Remember: every load requires two conducters, one
to take the electrons (holes) from the source to the load, and one to
return them back to the source! Another thing to do is mount a 14V LED
immediately above each CB, wired across the CB. That way, if the CB
opens, the LED above it will be on, except in an intermittent load,
such as the flap actuator. There, if the CB is open, the LED will glow
when the flap is actuated. Paul
