Trying to find a 110 volt power supply to power a 12 volt car radio for installation and sound testing. Looked on-line and need a recomendation as to what to use/buy.
Thanks, Greg |

I use a standard battery charger for things like that, but what do I know, I'm just an electrical engineer.....
If worried about overvoltage or noise, put a battery on it at the same time. I Also use PC power supplies, but when using them out of the PC case, you will need to short (temporarily) the blue wire to the chassis to get it to turn on. I found some aviation quality adjustable DC power supplies at a salvage yard & bought two for $40. (they are worth about $1200 ea.) |

Thanks Stu Been working on aircooled cars since I was a teen, to troubleshoot all electrical you can power everything by using a battery charger. You do need to pull the power wire off the coil or you will fry the points and some aftermarket pickups like the pertronix. QUOTE I Also use PC power supplies, but when using them out of the PC case, you will need to short (temporarily) the blue wire to the chassis to get it to turn on. Or just twist it onto a ground wire (IMG:style_emoticons/default/wink.gif) BTW I wasn't being pissy, just I see no reason to tell someone to go spend money when they likely have something that does the job right in front of them. |
