I have an interesting problem with my 68 XR7. I replaced the side marker lights with the bulbs listed in the old Sylvania catalog.
Put the driver's side light in and it worked!
Put the passenger's side light in and the headlights dimmed, the front turn signal lights went out and so did the driver's side marker.
I pulled out the passenger bulb and it went back to normal. I decided I had a short in that assembly and left the bulb out.
Obviously, when I drove it later that evening, the headlights started flickering, the side marker light went out, the turn signal lights and the dash lights went out as well.
The next day, I pulled the driver's side marker light out and the rest of the lights went back to normal.
I don't have a shop manual yet (on order) so I don't have a wiring diagram. Is it a safe assumption to make that all of those lights are on the same circuit and that BOTH side markers have shorts?
You'll have to forgive me...I'm new...
