I have a 2003 CC Ovation. Try to replace Pioneer Flip up CD-AMFM-Back up Camera. Now when I hit the master switch beside the pass seat nothing happens. Have checked all fuses at driver side and in pass rear side. Nothing I do seams to work. Gen works and charges. all plug in rec work. No over head A/C, no overhead lights. everything that works from Domestic switch does not work now. Any ideas. Called CC two days ago, still waiting for call back.

You are going to have to step by step trace the power from the batteries to the fuse panel. The chassis battery is suspect since you were working on the dash radio/camera. Check at the battery disconnect solenoid for power. On many disconnect solenoids, there are actually fuses on the solenoid body, check that they are good. If you jumper the two large terminals on the solenoid, you'll bypass it completely. If still no power, you should go back to the battery and trace the large wires to the disconnect. There should be a large circuit breaker, make sure it's not tripped.

You'll have to repeat the same steps on the house batteries. They are the ones that power the overhead lights, water pump, thermostat (that controls the A/C) and many other systems.

Your information was well received. IT Worked. Thanks at lot. Now I am back to getting power to the new Pioneer CD-AM-FM, Camera. The Pioneer harness has red, yellow and black wires. Now all this is on the house batteries which I am not getting power. What if I hook to chassis side of the wiring?

Most often the dash stereo is powered by the chassis battery. Often the power is 12+ through the ignition switch, 12- ground, and a second 12+ source that's not switched to power the clock and preset memory. Many RVs have a SPDT switch that can be used to choose between chassis/ignition and house power. This allows radio to switch on/off with ignition when driving, and when camped, the power is supplied by the house batteries so you don't have to leave ignition set to ACC.
