Erkan,
According to the shop manual, the hot lead to the brake light switch is
GREEN and should begin at the fuse psn A4. If you have a 12 volt dc meter
check for 12V at the GREEN wire entering the brake light switch. If no
meter just use a 12 V bulb and and an alligator clip to ground to make a
complete circuit. If there is no voltage, your GREEN connection at the
fuse may be corroded or the wire could be broken. You better have 12 V at
the fuse psn at GREEN. If you have 12 V at the fuse but none at the
switch, check the GREEN from fuse to switch for continuity with an OLM
meter. If you dont have a meter, you can go to your local Home Depot or
LOWES and get one for about 15$.
I have a 3A and I am not sure if the wiring is the same. If a 3B is more
like a TR4 the wire color is still GREEN at the fuse and at the switch.
If you have 12 V to the switch have friend press break and check for 12 V
at the switch lead to the lights (wire color GREEN/PURPLE). IF no 12 V
switch is defective. IF 12 V after switch, check wire continuity from
switch to each light, color GREEN/PURPLE. This is a simple circuit. If you
have no voltage to the fuse, A4, you better check your ignition switch,
The wire is light-green and either is loose at the ignition switch or
broken OR your ignition switch is broke.
GOOD LUCK
