Light help

[Lorence]

66 charger.  Have headlights only.  No parking lights no tail lights no brake lights no dash lights.  Brights work.  Where to start?  Any help would be appreciated.  Thanks.  JZ

Did they work and then quit or is this after a restoration?

Do you have a multimeter and know how to use it? And a wiring diagram?  I would start by seeing if there is power to the switch and the switch is working the way it should.  Then I would move down the line.  It is a pain, but being systematic will ensure you get it.  You can also make educated guesses and if fortunate, cut out some intermediate checks.

..in the fuse box. Bet you have no dash lights either. OH.. and you won't have front park lights in a '66 when the headlights are on...
