Stereo install, no 12V, help troubleshoot

[Sthompson]

thanks for the help everyone. Particlewave, the idea to check continuity from the fuse to the 12V power is what helped me solve it. I had continuity from one end of the fuse, not the other. So the fuse was blown! Maybve there was still enough contact in the fuse to register continuity, but not enough to run the 12V, because I checked B2 about 5 times before my original post. Glad that's all the problem was..

My car is '97.

"On my 98 the alarm sounds when the radio alarm wire is grounded. Don't know what year his car is....guessed an early car since he is replacing a CDR-210"

What should I do with the radio alarm wire? I am still getting the honk.

You guys are great, btw. Really appreciate the info. I've had my car for 10 years, and this is my first time posting to the board.

Had this issue recently on my car, as I understand it the original head unit has a felt sheet that prevents circuit meeting when alarm wire installed, ensures if parked with hood (English) down and someone tries to slide unit out the wire earths and alarm sounds. In my case simply disconnected and insulated wire and all good. No alarm feature on radio but heh park with roof up!!!

Don't leave as it is or if cage meets with radio the system will earth and sound alarm. Not good at 4 am as I can attest, neighbours not best pleased.

If it is just a short honk and it does not put the car in full alarm state (lights and horn), the honk is most likely not related to the radio alarm wire. More likely the glove box or one of the doors or one of the hoods is not reporting closed to the alarm system. Ground the alarm wire and see if the alarm goes off, if it does, insulate it.
