Hi all,
Been using these forums for years, and I’m back after some time - such a great resource.
I have a question. I bought a new Kenwood DDX9019DABs headunit as I wanted to have wireless CarPlay. I’d installed head units in previous Honda’s so I more or less knew what to do.
Everything was going fine, and I connected most things except the DABS aerial. I then plumbed the cables down behind the opening and under the centre console path, Bluetooth mic to drivers side footwell etc. It got dark so I left it for today to continue.
When I went to test it today, the head unit didn’t turn on. I checked connections and no luck. Checked continuity on the cables and all fine, except no power at the main wiring harness. Weird I thought, so I looked at the fuses and a chart I had to find under dash fuse 37 was blown (7.5A, it’s for MICU) and this eventually leads to the positive power wire on the Honda audio wiring harness. I replaced it, tested and fuse stayed good, but the head unit still not working. Again, no power at the main Honda audio wiring harness.
How could this be if the fuse is good? I don’t understand what else could be stopping power coming to it. I even took the original/stock head unit and connected it back, but it doesn’t work (proving no power at the harness). The only other two fuses are the No 2 50A under hood one and No 16 15A one, and the 50A goes to many more places also.
Any advice and thoughts welcome!
Thanks
Andrew
PS see part of the circuit diagram showing the purple wire which is the positive on the audio wiring harness.
