Hello Group,

Just replaced a power antenna with a factory rebuilt unit for a 1994 XJS 2+2 convertible. Upon connecting the white power plug to the unit the antenna went up in full extension. My question is the wiring set-up. The antenna stays up all the time and does not retract when the is radio on or off. Noticed something interesting today. When I opened the trunk and waited a few seconds the antenna retracts then when the truck is closed the antenna fully extends. As the second owner of the car I am wondering if the wiring is crossed some place as the prior owner had the unit unplugged and the original motor was fried. Any suggestions?

I've attached two pages from the "XJS 1994 Update" I found somewhere online. If yours is a V12, check out pages 55 and 57, "Right Rear Components". There is something called an "Antenna Retraction Relay". Maybe that's worth checking out.

Bill thank you for the reply and the diagrams.
