I'm a little confused by the ign sequence.

I get:
Ign key pushed in- starter button works
Turned one click side lights and headlights
Turned second click- red alternator light illuminates.

Surely this isn't correct? When should the sidelights in the headlights and on the wings illuminate? ( I have power to them but only seems to be when the headlights are illuminated.)

Will.
