Stereo and backup camera inoperative.

[Rkortan]

When moving my 2010 Winnebago Outlook recently I found that the stereo and backup camera are inoperative. I have checked all fuses on the chassis and coach all are good.
When the door is opened there is a small blue light on the stereo that lights up and then goes out at the same time as the dome lights. I assume that is a different circuit than power to the unit.
I have had a battery disconnect switch on the chassis battery that has been used many times recently. I was wondering if using the disconnect would cause a problem. I do hear the relays clicking every time I reconnect the chassis battery.
Also I guess it’s possible for the head unit on the Jensen stereo to have gone bad.
Any ideas will be appreciated. Thanks.

I would venture to say there is another fuse block somewhere.

Rkortan-

First off, welcome to iRV2!

Second, you should add a "signature" to your profile. It contains whatever info you want; most people put info about their coach there, so they don't have to type it into each message. Instructions for adding a signature are here.

The wiring diagrams for your coach are here (for a 29B) or here (for a 31C).

The wiring diagrams for the 2009 29B and 31C are more complete.

I would pull the stereo out and check for more in-line fuses. I had an issue on obviously different RV manufacturer. It is an old Jensen with a detachable face and the security light was always on, but the unit itself just would not power up. Which made me think that the unit itself was bad in some way because all fuses in the cab fuse block were fine....

Pulled the stereo out and tucked pretty far back there they were. There were two in-line fuses behind the head unit with one of them being blown. Replaced the fuse and no troubles since....

[Rkortan]

I still have some troubleshooting to do. I was hoping for an easier solution than pulling the stereo but it looks like that’s where I’m heading. Thanks.

[Rkortan]

I ordered the special tools to pull out the stereo. Hopefully that will allow me access to a blown inline fuse.

[Rkortan]

Well I have made some progress.
There are three inline fuses and they are all good. The only circuit I can’t identify is the yellow wire at the left bottom corner of the radio.
It does not have 12v under any circumstance that I try.
The radio does have 12v on the right side where all the speaker wires are located.
I was thinking of just applying 12v to the yellow wire to see if it does make the radio work.
Any help is appreciated.

Rkortan-

That switch above the radio, marked RADIO POWER... Does switching it one way or the other solve the problem?

By the manual (link here, page 3-6), the COACH BATT switch must also be on for sound to come out of the radio. That switch is near the entrance door or the galley, according to the manual (page 6-6).

[Rkortan]

Doesn’t make any difference how the switch on the console is set. The battery disconnect near the door doesn’t change it either.
Although I will check all that again just to be sure. Thanks

Yellow wire should be a trigger for your reverse cam.

Put her in reverse and see if she energizes

[Rkortan]

Ok I’ll check that on Saturday.

[Rkortan]

The yellow wire gets 12v when in reverse.
Now I’m out of options. Everything has power but stereo/monitor does not turn on.

Do you have power to your inline fuses?

Is your stereo one unit and the monitor another unit?
They are both inop?

[Rkortan]

The online fuses are good. The stereo and monitor are one unit. I’m leaning towards just a bad unit.
