[900RallyX]

Probably a dumb question, but i have a 92 turbo and the antenna isn't going up. I don't hear the motor turning, and I have power to the red wire at the antenna all the time, and power to the green (signal?) wire when the radio is turned on. I have no motor movement (or attempted movement). Is there supposed to be a ground wire on this thing somewhere or is it just grounded through the mounting bolts?


I'm assuming the antenna motor (or internal wiring) is bad, but I bought the car used and it's always had this problem so I just wanted to verify there isn't a missing ground wire.


Thanks

I just replaced my '87 900 antenna with a nos 1 from a 9000 (just had to put in a makeshift bracket & bypass the connection adapters) Anyway you should just have the red & green wires...odds are the motor is shot

PS. currently a few listed on Ebay if u find the motor is indeed shot & are looking for a replacement. If you go with a replacement don't worry about the bracket you can rig something up to work if need be...same with the connections...I just got some some male/female crimp connectors to tie mine in...my 9000 antenna replacement works perfect on my 900

There is also a black wire. It typically is grounded to the body, but if it's damaged or missing the antenna won't work.

You can trigger the antenna with 12v to both red & green wires, and ground to the black wire. If that doesn't work, the motor is probably shot.

this is true on the black as seen in the pic...my bad

Thanks, it was indeed the black ground wire that was loose. Was chafed through and floating in space.
