Found the solution was to use an old 22 caliber bore brush on the female
bullet connectors at the switch. Hey, the bulbs even seem a bit brighter than
I remember. I guess the corrosion was slowly adding resistance.

Diagnosing lamps is easy. Use a test light. Anywhere in the circuit you
either have power or you don't. Start at the brake switch. If no power on
the input side, check upstream (the fusebox connections). If power in but no
power on the output side with pedal pressed, replace the switch (commonly
bad), or it may only need adjustment. If power out with pedal pressed, move
on to the brake lamps. If no power at the lamp input, look for a loose or
corroded connector in the harness between the switch and lamp. If power in at
the lamp but no light, it may be a burnt out bulb. Otherwise look for loose
bulb connections or bad ground connection.

Need some help finding where my brake lights have gone. I have, so far,
cleaned the #3 fuse connections as that seems to feed the green circuit. I
have cleaned the bullet connectors in the boot. Checked the bulbs. Removed
and
tested the switch on the back of the pedal box. I did get them to come back
once, but subsequent pushes on the pedal failed. Ibm stumped as to what to
try next. Any suggestions would be gratefully accepted.
