[VAC] Re: 12 volt 101

Don,
 It appears as though your '76 coach is different from our '68 in that
regard.

Naturally, only one wire to a light will go through the switch, and it'd
normally be the "hot" or "+". The ground or "-" goes from the battery to
the light, with no switches and normally, no fuses, in the run. There's
nothing to stop A/S from using the metal skin(s) as the '-' conductor,
and that's apparently how your coach is built.

                                    <<Jim>>
