[C320-list] Install 'cigarette lighter' chargerat ignition switch housing

Bruce,

While I agree that adding a low rating fuse to the additional power port 
will protect the instruments from a "brown out", I wouldn't think that 
anything plugged into the engine pod should be drawing a lot of current. The 
problem with fuses is you need to carry spares in case one blows, which is 
why I would go with the breaker alone.
