My Coupe just got out of the shop for electrical work which included a "new" headlight switch from a '68 Crown, a repaired T/C AM-FM signal seeking radio and a replaced turn signal switch. The amp meter periodically starts bouncing back and forth with or without the headlights being on. When the headlights are on the dash and headlights flicker - any ideas from the veterans out there will be greatly appreciated. Marc 67 Crown Coupe
