QuestionQUESTION: Hi, I'm trying to replace the power antenna in my 1991 Mazda 929s. The antenna motor died out. I am still using the stock radio. I've bought an aftermarket replacement power antenna and got it installed but now my radio and new antenna does not work. I've checked the fuses and all is good. One thing that I removed and did not include back in the swap was a little relay box that was connected between the stereo and antenna. (I think it controls the antenna.) I've put everything back, including the relay box and my stereo still doesn't work. What can be some possible problems or solutions that I can try?
Thanks for the help!!
ANSWER: all the electric antennas i install are positive power they use ground and +12volt to go up or down
the Mazda is the only car that works the other way it needs negative -12 volt power to go up or down
you need that relay back to switch the polarity and check both of the fuse boxes

QUESTION: Thanks for the help. But now, I've put back the old antenna with the relay back in and now my stereo doesn't work. I've checked the fuse boxes and nothing is blown. My stock stereo doesn't have a separate fuse itself so I'm at a loss.
I appreciate your help.
Answerthere are 2 fuses for the radio in both of the fuse box but one is not label radio it is back up ,memory or cigarette lighter
i also remember that there was a fuse on the back of the radio on the 1989 and also on the back of the 626 radio
if you don't find any bad fuse pull the radio
