Question about Kenwood KAC-7202 Car Audio Amplifier
Recently re-installed my 7202 kenwood. everything was working fine when disconnected from my old suburban, and when i installed it in my new suburban (exactly the same way as before) i get red indicator light on the amp. the fan and the red light are the only things that work. double and triple checked to make sure everything was wired in correctly, and still no changes. why is my amp immediately going into protect mode and what can i do to remedy this? someone please help, i am DYING to make this work.

SOURCE: Kenwood KAC-7202 wont turn on
I have found the problem to my Kenwood KAC-7202. The amps fan was the only thing that would come on thats it. So I started checkin zener diodes cause all transistors checked out fine. So I remember readinf about a guy that had same problem and took it to a shop and they said it was some diodes. Well, thats what I was thinkin or the transformer. It turned out that 1 zener diode was no good, diode D9 1ss133. I took a zener out of an old vcr I use for parts and put it in and the fan came on as usual then the red light. Then I hooked my mp3 player to the rca input and hooked up some speakers and it works great. Hope this helps you other guys with the same problem. Check your zener diodes with a digital volt meter, if you get any measurement other than the reverse impedance which will read between 600 and 1200 ohms some lower or higher and then reverse the leads on your meter and if you get any reading it's no good and the reading will be 0-50 cause mine read 047 ohms.
