82 power antenna ????? Help
Ok here it is. A prior owner installed a new power antenna and never connected it to the relay. However, I think it is an after market antenna. The wires are not the same color code as the shop manual shows. There is a red, white and black wire. I am assuming that the black is the ground and the other two (red and white) one is for upward movement and one is for downward movement. Also on the antenna there apears to be a relay. Hmmm. 1. How do I test this antenna/figure wiring nomenclature out without damaging the electrical system by touching two wrong wires together? 2. If there is as relay on the antenna itself, will the antenna relay installed in the car from the factory work in series with the relay on the antenna? If not, which relay should be bypassed?
Thanks

Red=direct current (when key is in Accessory position)
White= Normal (key on)
That would be my guess - disconnect the red if you can and try it out with engine start and "Radio" on".
I don't think you have seperate connects for antenna up/down.

Hi,
My 82 had a after-market antenna replacement when I bought it. The previous owner just had the antenna raise when the car was turned on and lower when the car was shut off. I tried to connect the wires to the antenna relay, but I could not get it to work. Good luck, let us know how you make out.

wires
The red and black are not for the power to the antenna.Your radio has to have a wire just for the antenna.Not all do.Mine had a blue wire that hooked to the power lead to the antenna.So the radio had power to it but the antenna only goes up if you turn the radio on.

Reason I ask - got a new Kenwood I want to install and was hoping all the wires would match up to the existing wireing harness and I wouldn't have to figure anything extra out to make the modern radio work.

it depends on the radio, and it's in the manual. some give only about 5 or so volts to switch a relay, usually then the wire is also used for an amp switch, some however are capable of delivering the full 12V required to run the antenna without a relay.

I found this thread on the web:
http://iotech.no/corvette/technical/...%20antenna.htm
sounds like the older power antenna relay's alternates current direction for up/down. If you've got a newer replacement antenna, and the old relay, perhaps that is causing your problem.
According to the artical, you need to replace your original relay with a modern compatable one for your replacement antenna. This is the problem I think that I am having.
Anyone know where you can get a "standard 30/40 amp normally openautomotive relay"? that the author refers too?

I wonder if a standard IEC ice cube relay would work. My problem is the wires on the replacement antenna have never connected and I am missing the wiring harness the goes from the origianl relay to the antenna. I just don't know which wires go to what and if the original relay will work in conjuntion with the relay that is on the replacement antenna.
