Haven.t checked voltage while off, only because I don't want my kids to find me electrocuted when they get home from school. Seriously though, you may be right about 2 wires. I'll check for an extra unattached one and see if that changes things. By the way, the display doesn't even turn on when I press the on button, although that little red remote light is still on. You know, this radio used to turn on while the key was out of the ignition, so that's why I'm wondering what could be the problem. It does sound like it's wired to the ignition though, and I know that I ;eft it at the mechanic for some work, and he may have rewired it back to keyed. so I'll report back when it gets cooler here. It's 90 degrees outside and in the MH it's worse. Yes, i have air, but it takes awhile. Thanks for the input.
