My 24 volt Toyota radio, with FM crystals starting at 90 Hz and going down
has been pulled, and I've got a new Pioneer CD deck en route via eBay.
I suppose it's time I start to design a circuit to power this thing.
I have a 24-12 volt converter ready to go, and there are two items I want to power with 12 volt, the stereo and a CB radio. The converter puts out 10 amps max, so I'm OK in terms of current draw.
He4re's the rub, it's not just as easy as wiring from the old radio power source, because I need a constant source of 12v to keep my radio settings once the igniton is off.
Can anyone describe an easy way of doing this? I will purchase a small 12 volt fuse box and ground bus strip.
Thanks for the help.
