Power Antenna

[Ray Schick]

Does anybody have any issues with their stock power antenna & radio? My power antenna quit on me , it was working fine , checked all connections on radio & antenna nothing found. the plastic whip on the antenna is fine , jumped the wire on the antenna and it goes up and down. any idea's? I'm guessing it in the radio.

The antenna has a separate 14 amp fuse from the radio's 7.5 amp fuse. Did you check the antenna fuse as seen in picture below:

Checked it , fuse is good.

Unplug the connector on radio and make sure antenna feed connector has 12 volts with ignition on.  It would be on the brown wire (see Fig 12-116 R-Radio Connector if you have a shop manual).  That would at least let you know you are getting 12 volts to the radio antenna feed. From there, check the connectors on the radio for the antenna up and then antenna down connections pushing and then pulling the antenna control know. If your antenna feed is getting 12 volts to radio, and you are not getting the 12 volts to the up connector/down connector you know it is something in the radio probably related to the push/pull radio knob and antenna relay/switch mechanism. It has been long time since I looked at how that actually works but do not remember it being too complex.

I have 12 volts going to the radio,its got to be something in the up and down knob mechanism in the radio, bench tested the antenna , it works excellent

Just to be 100% clear, there are two 12 volt feeds at the radio connector - one for the radio, one for the antenna.  If you are getting 12 volts on radio feed but none on the antenna feed at connector antenna will not work.

Try spraying some electrical contact cleaner into the switch.   If that doesn't do it, I have good used switches. 

email me if you need one.   [e-mail]
