My Jensen VR209 radio fails to power on when switched to chassis power, but works fine on the house power switch position. I noticed this recently and was puzzled by the fact that the radio LEDs all light up, but the radio doesn't function on chassis power. While I was changing out my CRT backup monitor today I looked for a loose connector or wire and spotted a blue wire that was seemingly broken off from wherever it was previously attached. Now I am trying to figure out where that might me. I looked at the connector info and the online Winnebago info for my rig and still am having difficulty figuring this out. A blue wire should correspond to 12V 100mA out rather than power in. I would have thought the missing wire should be a red wire. Any thoughts on this?
