'lectrical question 200 89

posted by  someone claiming to be carl krall on  Tue Jul 17 05:05 CST 2001 [RELATED]

I sometimes want to listen to my stereo with the key off, but most of the time it's handy to have the key automatically shut it off. Now that I have an electric fan, turning the key on with the car warm means that the fan will run as well.

So I'm thinking about running a second power wire to the stereo, with a dash switch that would enable power with the key off.I was going to buy a stock Volvo rocker switch (was thinking of using a Hazard-lights switch because of the indicator light) at a junkyard and use that, which means that I can't do a DPST (unless someone knows of a stock switch that is DPST) solution.

If I use SPST, do I need to use diodes or something to protect me in case I have both switches closed at the same time (e.g. I'm sitting there listening and my girlfriend gets in the car and I start the car with the other switch still on)? If so, what should I do, wiring-wise?

Or will the stereo just draw its 13v no matter how many live feeds are running to it?
