Help Needed: 2003 SAN Stereo
 

Hey Guys,
I was just getting the boat pulled out and 'summerized'. I got a new battery this year and wired it up, the terminals are backwards to my existing, and I botched the connections and wired one backwards. After freaking out and disconnecting everything, let it cool down and set it up correctly. The boat started just fine. But now my stereo is not working...

I did blow the ANL 200 fuse that is inline to both amps. Since been replaced.

I checked all stereo in line fuses and they are intact. There is minimal to no draw on the yellow (memory?) line to the CMD4. The yellow will spike a .2-.1 reading when first connecting the multimeter, but then drops down to 0.
The red main power has a constant 10.98 volts.

What am I missing?

Any and all suggestions are helpful. Thanks!

To start with, the yellow is actually the main power for the CMD4. The yellow is the constant B+ and the red is switched IGN/ACC. You need to trace back on the yellow BY till you find where the circuit is broken. There is typically an inline fuse holder just off the back of the head-unit on that yellow wire.

The yellow has a 15 amp fuse just off the head unit. That fuse was okay.

Ok, if there is still no battery voltage on that yellow wire, you need to keep back tracking that circuit. Theres probably a "stereo" fuse or breaker somewhere thats popped.

So both (red and yellow) should be at a normal 11-12 voltage reading?

And thanks for he help by the way!

Yes, both the red and yellow will need to have battery voltage before the H/U will turn on.
