after the Park Life Blat, this morning I set about fixing my non-functioning brake lights...
the switch is OK (but I also have a replacement) - closed circuit when plunger out, open circuit when pushed in
bypassing the switch with 12V lights the rear lamps
putting 12V on the switch and closing it (ie letting the plunger out; either switch) lights the rear lamps
however, the feed to the switch has 12V on it
but when I connect that to the switch and close it, the rear lamps DON'T light!
similarly, if I short the feed to the switch to the output, the rear lamps DON'T light.
it is almost as though there is 12V there but insufficient current to light the rear lamps
is that possible? if so, what would've caused that to happen (ie what do I need to do to fix it?)
