Like many of you I have had it with the factory antenna on my 93 Pathfinder and decided to replace it with an aftermarket--Metra Autoworks AT-PW22. In order to mount the unit easily in the wheel well, and to keep from buying an antenna adapter) I used the old Nissan mast(Diversity Antenna). To get to the point, I located the antenna power line from the radio and when I connect it to the antenna the line drops from ~13.8V to ~2V. I tried a little test and removed the ground from the antenna and the line stays high. Further research I discovered that the radio must use the chassis for it's ground. In short, I'd like to use the antenna the way it was supposed to work but don't understand why it's not working. Can somebody please help? I have looked at the factory wiring diagrams, called highend-auto stereo installers, and even the dealer and they all seem clueless and nicely send me on my way.
Thanks in advance!
