Default Why won't this light turn on?

Are you an auto mechanic by trade? From your above decribed behavior,
I'd say so.


Auto mechanic? Bummer. No, a software engineer.


Have you checked to see if any of your breakers have tripped? Include
any GFCI's in the house as well. You never know how many stupid things
someone before you may have done so, putting an inside light fixture on
a circuit after a bathroom or garage GFCI is certainly possible.


I first checked all the breakers and GFCIs. They're fine. When I turn a
breaker on/off, it affects all the other lights in the box. Curiously,
the switches are on two different breakers. Before starting to replace
the second light switch, I was fortunate to accidentally flip another
switch in the box and to my shock, the light turned on. I found the
other breaker and turned it off.

How do I use the tester to verify that there's power coming into the
light switches? If it was a single switch, I wouldn't be asking such a
lame question.



Did you look at the site referenced by Speedy Jim?

What you have is the three way switch configuration. Did you replace
the switched with the proper type (Three way)?

The four lamps are in parallel.
