RADIO PROBLEM

Stereo systems typically have two positive power feeds,
One is constant (or battery) power. This power keeps your clock and radio settings. It may or not me the primary power source for the stereo's internal amp etc., I'm not sure on that and it could possibley vary based on the stereo.

The other power feed is switched by the ignition. This is what turns the radio "on." I'd say first step is to locate both of these wires, and make sure you're getting juice to both when the ignition is on. You can use a multimeter or a simple test light for this.

If you're getting power to both feeds, then I'd say it's a fairly safe bet that the radio itself is toasted.
Actually, one more thing, look for any fuses in the area of the radio itself, or directly associated with the power feed lines.

The good news, if you determine that you're getting power, and the radio is just gone, the radio should be a fairly standard size, I believe it's called DIM, not sure what that stands for.

Check out Crutchfield.com or even some place like Overton's, but Cruthfeild will give you better advice. I'd imagine it should be pretty easy to find something that will be plug and play or darn close to it.

Hello,
I have a 1997 Nautique it has a Clarion M8430 radio.   The clock is showing, but the radio station does not, and there is no sound. What should i check or is the radio bad?   If it is the radio, does anyone have a suggestion on what type of radio can be put in the boat in place of the stock radio?   If i have to replace the radio i wold like to find a replacement that is just plug and play.
thanks
max
