83 AE71 wagon, no tails/side markers/interior lights, and brake lights

[almostreallygood]

Since I bought this car about a month ago none of these lights have worked (correctly). I can get the tails/interior/side markers to work by removing the tail light relay and jumping 2 of the 3 pins, but even then the brake lights still don't work. tried a new relay and that didnt work.

 I tried removing the brake light switch and jumping it but had no luck. bulbs seem to be fine as well.

Is there a common place for the wiring harness to fail on these cars?

No common faulty wiring areas that I know of..

Do you have a wiring diagram for it? You should be able to trace the circuits back to a common point on a diagram, and as you do note the colours and see if they agree with the car itself.

Maybe someone has had a play with it and assembled it wrong, or maybe something has broken. Most common problems involves bad earths, so grab a $10 multimeter and see what resistance you get from bulb to body in each case.

Let us know what happens and we can go into more detail.

Found this wiring diagram on the net.  It is for AE71 lamps only.

Here is the "legend" for the wiring diagram.

The good KE70 one is here, very little will be different.
