I'm replacing the aftermarket in dash car stereo in my Chevy class C motorhome. I thought it would be straight forward, but the p.o. put a chrome push button in the circuit. Then, it would seem, another p.o. cut the wires to the button and, as of now, it's not functioning. Further, the stereo functions with the key on, but not with it in the "accessory" position. So I have a non functioning button as well as a non functioning accessory key position. (I'm not sure what else powers in ACC, but the gauges don't move).
<Can't figure out how to upload photos>.
It seems the intent of the button may have been to easily power off the radio during storage to eliminate battery drain. If so, this makes sense and I would like it to function again. I also would like the accessory function restored.
Here's the layout...
There are two attachment points or "posts" on the back side of the button. (It's a simple push button. Push click, push click.) One side carries blue wire, the other orange.
On the orange post, three wires are connected... The first is attached to a single blade of a flat two blade fuse and plugged into the fuse block "pwr" space. It exits with a good inline 20 amp fuse and attaches to the buttons 'orange post'. Two orange wires exit this post. One goes to the stereo accessory wire (not working) and the other is cut. (It may be worth noting that there is a cut piece of orange wire taped onto the blue wire on it's way to the battery just inside the pass through hole in the firewall.)
On the blue post there are two wires... The first is connected from the battery (via an attached post) to the 'blue post'. The second exits and goes up to the stereo, but is not attached to the yellow power wire. It too is cut.
The black ground wire is connected to the stereo then looped and taped to the wires of each button post before being grounded to the metal body.
The current stereo power wire (yellow) is not routed through this button, but is direct wired to another "pwr" port on the fuse block.
Please help me understand this button and let me know where to reattach the cut wires to make everything function properly.
Thank you.
