Power antenna

[Tony S]

The original power antenna on my 76 is long gone. There was a replacement that didn't work and looked like it was wired by Rube himself. After removing all the junk and antenna I found the original power plug and there is power from the switch so I believe it will work. The problem is any new power antennas don't seem to be compatible with the original 3 wire power lead. All the replacement antennas, one of which I have all have a red ,green and black lead with a relay which I would think is a polarity switching relay. I know I can get he antenna to work with rewiring but I would like to keep the original switch and harness since they are already there. Any thoughts?

Check the original wires...one may simply be a ground wire. Since the antenna has to be grounded for proper performance, an additional ground wire is required on fiberglass cars.

If it's not a ground wire, it could be for radios that have automatic up/down when the radio is turned on and off.

Once you determine which wire is for what, you may simply need to cut the original power plug off and make butt connections.

The radio in the car had the power antenna trigger wire and I just by passed the switch all together. Now the antenna works with the radio switch.
