So i just noticed today that my power antenna is not working, i dont know how long is has not been functioning since i rarely drive the car and even less so use the radio, so this could be a year or two old problem. I pulled the antenna out, my first assumption is that it has gone bad, are there any good ways to test the functionality to determine if it is a wire gone bad that hooks up to the antenna or the antenna unit itself. i tried to hook a power supply to the antenna connector after it was removed and it tried to work which makes me think there is a failure in the wiring. To test this would i just use a multimeter to hook up where i removed the antenna? does anyone have a wiring schematic for the antenna? I have an aftermarket radio and setup a switch to raise and lower the antenna which is hooked up correctly, i used the 3 wires that hooked up to the old radio and soldered them to a switch... My guess now is that there is a problem in the wiring, maybe something has come unplugged so any information about the wiring for the antenna would be great.

I used the following post when wiring an aftermarket antenna (with aftermarket stereo) in my 260z (see post #5). For the full wiring diagram I suggest looking at the factory service manual available at http://www.xenons30.com/

Pulled the antenna to test it, still worked so there must have been a break in the line somewhere? decided to run new wire. Is there anyway to boost the antenna, seems signal never has come in too great....
