2.4L Ignition Coils Problems HELP!

[mark65]

Can someone with a 99 or later 4 cyl. do me a big favor. I need to know the actual voltages going to the coil with the key on, engine off. there is just one connector with 3 wires. there should be 12 volts, ground, and I am unsure of the third wire. I will greatly appreciate if anyone can check there car. I have a wiring diagram, but it does not show actual voltages. All I need to know is the voltage (if any) at the coil connector with the connecter UNPLUGGED and the Key ON, Engine OFF. Thanks.
