Help with electrics

Hi guys,

 

I've got a bit of a problem. You know when you turn the engine off, and leave the key in the ignition? The radio stays on right? No!

 

Until recently, this worked no problem, but now it'll only work on low volumes. As soon as you start to turn the volume up, the radio cuts out. As soon as it cuts out, it turns it's self back on again, then off, then on, until you get bored and take the key out. :( It's an alpine 60W, so it's got a direct feed from the battery. At this point, I guess there's a feed from the ignition, telling it to stay on, and the feed from the battery, and nothing else, which makes me think it's gotta be the battery, but the voltmeter says it's OK.

 

When the engine's running, the radio is faultless, so I don't think it's a loose connection / bad earth / ignition switch.

 

If anyone can give me any pointers to help me figure this out I'd be really grateful.

 

thanks guys

 

Chris

I blew up a connection in the ignition for this function, so now when i turn off the engine the stereo turns off too with the key still in, it will only now work with the ignition lights on, have a new switch but its 1 more of those jobs i keep putting off as its a right pain in the butt.

try disconnecting each speaker and see if still occurs (short circuit protection might be cutting in)

 

or

 

steal the one out of a friends car and see if the problems still there. at least it would prove your wiring.

sounds like the igniion live cannot provide enough power when you crank the volume up and the stereo starts to need more power so cuts out because of this!!
