Nissan Repair: relays, nissan 200sx, beam headlights

Question
I am working on a 7/86 Nissan 200sx, when you turn on the headlights none of the lights work. The high beam headlights will come on but that is all, the brake lights also are not working. I have checked the switch and it is working properly, the fuses are also good. Where can I find the relays for the lights? Would this be causing the problem?

Answer
Brad,

The headlight relays should be under the hood in the relay box.  If both low beams do not work I would think the headlight switch.  If you tested it you need to make sure there is a complete circuit for both sides.  The Japanese fuse each side independently for safety instead of having an overload breaker like United States manufacturers.  If the car has been hit or the front end has been off could be a tell to look for damaged wiring as well.  The brake switch is powered from the same source so look at the headlight switch.
