I replaced all the bulbs in the front and rear wiring harnesses and replaced both rear brake/turn signal sockets in my 68. Headlights, markers, tailights all come on when light switch is on. Both tail lights become brighter when brakes are applied. Left turn signal works both front and back, as do flashers. Left turn signal dash light indicator also works. However, right side front and back don't flash and the right side dash turn signal indicator does not come on at all when flashers on or right turn signal applied. Test light works when applied at all sockets. If the dash light turn signal indicator doesn't come on (blown bulb?), does that affect the turn signals in the front and rear? What am I missing? Any insight would be greatly appreciated!
