Default 13 VDC switch

You mean I started a new idea? It sure would be handy to plug in
portable devices into the cigarette lighter socket source and not drain
the battery with engine off. OR in case of charging system failure
some non-crucial devices could be turned off automatically. We need
this before November.


Ok, I'm operating from memory, but if the objective is to turn "on" only
when the alternator is active, trigger your switch with the stator output -
should be 0 when the alterntor is inactive, and about 1/2 the output voltage
when the alternator is charging. A 6 volt relay would do the job, eh?
