Hi Pat, Maybe I can help answer your brother in laws questions. The power supply draws it's current through the orange wire, which has already come through the light switch. The dimmer switch controls the power going into the power supply. There were different styles of the power supply, but they all did the same thing, converted 12 volt AC to 200 volt DC. I've often thought about using the new car ones myself. If the plug could be adapted to work with the original wiring, it should be more reliable. 300ly, Don ----- Original Message ----- From: patrick grant <gran102@xxxx> To: <Chrysler300@xxxxxxxxxxxxxxx> Sent: Saturday, January 03, 2004 4:03 PM Subject: [Chrysler300] Fw: Power supply i visited my brother-in-law over newyears. i consider him a world class electronics engineer(my opinion). i left him with an old nonoperable dashboard power supply. since i have never had an operable one i cant answer his questions. he is fully confident he can produce working power supplies-not necessarily reproductions -but they will work for an economical price. can anyone answer his questions? thanks, pat grant ----- Original Message ----- From: "Stan Korzep" <skorzep@xxxx> To: <gran102@xxxx> Sent: Saturday, January 03, 2004 4:43 PM Subject: Power supply > Get home without incident?
