Weird one, but all electrical issues are. When I picked up my 64 1/2 coupe in September, everything worked except fuel and temp guage. Thanks to this site I learned about the small voltage regulator on the back of the qauge cluster. All was good. It is winter here in South Dakota and the coupe stays tucked in garage until spring. This week I installed Procar Classic front seats. Love ém ! Anyway, sometime during the process I noticed I had no courtesy lights, Ya know with the doors open, no lights. I did a full lights check and I found out I have no tailights either. Been staring at schematics for about a day. Fuses "look" good but I haven't metered them. Think I'll just change all fuses (only 6 of em). But can there be any correlation between courtesy lights and tailights ? I'm wondering if it can be the light switch. I'm sure I had courtesy lights and tailights when I laid her up for storage and can't think of anything I did since. Thoughts ? Maybe some one has had a similar issue.
