CB's trials remind me of a similar troubleshooting folly. I was working on an Oldsmobile that had no headlights. Headlights were physically there, they just didn't work. No wiring diagram, so I spent 2 hours tracing wiring, only to find out that BOTH headlamps were burnt out. Harry Yarnell perryman garage and orphanage perryman, MD hyarnell1@earthlink.net
