where is it coming from?

I have a ceiling light with two three way switches. Power comes in at the light with 12-3 going to each switch. When switch is turned"on" i have 120 v, when i turn either switch "off" i still have 90v i replaced both switches, disassemble the lighting junction box and rewired very carefully still have 90v any ideas

What made you start checking this? Was there a problem before?

I have a feeling you replaced something and miswired it when you put i back together.

Don't tell me, you replaced the fixture and took ALL the splices apart at the fixture?

i kept replacing the bulbs(flourescents) so i decided to replace with incads. while it was apart i checked just to see what i had. please believe me that the box for all the connections is wire right. have been over it numerous times i guess the 90v was cooking the ballasts?

Sounds like something is wired in series then.
You'll need to tell us exactly what wires you have in the ceiling and how they are connected, and also at both switches.

You should use a solenoid type tester, Because you will pick up phantom voltages with a digital multimeter. Depending on what you measured...

Yep, a digital meter will very often read voltage where there actually is none. The technical term is 'capacitive coupling'.

i have a wiggy. i'll try that thanks

Especially in this application and how its wired.

Actually, it's called "Inductive Coupling".

Capactive coupling is typically found on electronic ckt boards....the higher the freq the bigger the problem.
