Wiring diagram for Grounding switch with a pilot light. Cat # 1221-PLC

Sure you can find wiring diagrams , if you are in the States you can go to http://bbbind.com/free_tsb.html free wiring diagrams . But having factory service information from alldata or identifix Identifix Direct Hit online vehicle diagnostic system tool review is a lot better , shows pictures of ground location an gives description how the circuit works ,Pin point tests etc... I would suspect the switch before a ground . Check power at the switch an after the switch !

Open following link for cooper 277 wiring illustration:
http://waterheatertimer.org/images/Cooper-277-pilot-400.jpg

Wired as shown in illustration, the pilot light and the Load will come on each time switch is turned on.
The illustration show Load is light bulb.
In your case, the Load will be an outlet instead of light bulb.
So the Load will have 2 wires. The black wire from switch connects to brass screw on outlet. The neutral connects to silver screw.
Bare ground wires connect to green screws.

Your screw terminals are 2-brass and 1-dark.
Dark screw is considered 'common'

Leviton shows a 3-way 1203-2, but not 1201
Wiring diagram indicates that pilot light is ON whenever switch has power.

Check your instruction sheet that pilot light is supposed to turn on-off with Load.
I don't think it is, without additional terminal on switch for neutral wire.
And then it would only work on switch located closest to light.

You can wire this type of thing separately.
Buy ordinary pilot light or indicator light from WW Grainger.

I have wiring diagram for Cooper pilot light switch:
Look carefully at screw colors.
Pilot light turns on when switch is ON.

I have 120Volt cooper 277 pilot light switch here in my office.
Dang instruction sheet shows wiring for all kinds of cooper devices.
EXCEPT pilot light switch.

So I tested with multimeter and came up with following:
Key to any wiring device is color of screws.
Hot from breaker box always goes to dark-colored screws.
Neutral always goes to silver-colored screws.
Brass screws are for Hot wires from breaker or Hot going to Load
Green screw - ground

Hope this helps

The neon lamp inside of the switch draws very little current (milli, or mico amps) so there is no significant current flowing to ground.

As for your real question, there are several various types of 3-way pilot switches:
Load on: Pilot on
Load off: Pilot on
Some 3-way pilot switches have an external lead which allows them to be configured either way.
If both of your switches are the same type and are wired correctly, they should work the same.
If you suspect that one is defective, try swapping them.

Depends on whether you want the pilot to glow when the circuit is live (the main light is on) or to glow when the circuit is off. (The switch can be used either way, and I have used this switch in both configurations at different places.)

The wiring diagram is on the inside of the box.

In indicates that if you want the pilot light to glow when the circuit is off, then you only need two wires (the live and the return, usually colored black and white, respectively). However, you also need a ground. The instructions say that you need the ground for safety (and probably legal code) reasons, but I suspect that, without the ground, the pilot light won't work in this configuration.

However, if you want the pilot light to glow when the circuit is on, you probably need a three wire configuration (plus the ground).

Hope this helps.
