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?
