Wiring Question : 2477D : Replacing Three Way Switches

[InTheDark]

Hello

Currently have a light fixture controlled with dumb three way switch(s).

( Switch A ) has (2) black wires and (1) red wire. + ground

( Switch B ) has (1) black wire (1) red wire and (1) white wire. + ground

Would like to turn the three way into a two way using one 2477D.

Have REMOVED BOTH SWITCHES and have capped off all of the wires.

With the BREAKER TURNED ON :


( Switch A ) black wire that was connected on the bottom right black screw is HOT.
( Switch A ) red wire that was connected on the top right silver screw is HOT.
( Switch A ) black wire that was connected on the top left silver screw is COLD.

( Switch B ) black wire is HOT
( Switch B ) white wire is HOT
( Switch B ) red wire is HOT


There are two other switches in the gang box which ( Switch A ) is in and there are white wires there as well.

How do I turn this into a TWO WAY SWITCH using the 2477D?

Any assistance is most appreciated.

"Typically" the red wire goes between the 2 switches.
If it measures as 'hot' it might be picking up voltage from the parallel HOT wire. Try measuring this with an AC voltmeter. The actual HOT wire, measured to safety ground should be about 125VAC (not a value less than 100VAC)

I have seen odd things that should not exist, like 3 way switches wired on to 2 different circuits.
