Yet again, damn TURN SIGNALS!

[DRACO A5OG]

Congrats OP!

Marc, in your case it looks like a short in the tail light assembly. You see the the backing on the light sockets are lien to a PCB, a thin brittle plastic that over time and too much force will snap and as a result will short when the loose connection touches the housing. If you checked everything else, it may be time to look behind the assembly which requires you to remove it.

I fixed mine by gluing a piece of plastic onto mine to reinforce it, while I was in there I tightened up all the loose sockets, using a ratchet wrench extension and a hammer.

I had a blown fuse issue, blown bulb and finally I replaced the flasher unit (I replaced the original thermal 550 with an EL-13). When I remove the whole front right turn signal assembly from the chassis, the turn signal works; when I screw it back on it seems to short... I can't see where the wires could be broken and touch the chassis (which is fully painted anyways) !

I've been reading the different posts and it seems the following items should be checked:
-Broken wires creating a short-circuit;
-Fuses;
-Flasher relay;
-Steering column switches;
-Backup light switch;

My car was originally a 912 converted to 911 (engine, transmission and body work). I've downloaded a wiring diagram for the 912 and there seems to be a relay after the flasher unit ?!
Any other clues ?

Thanks,

Marc-André.

The front screw on the turn signal housing is causing the short-circuit; when I remove it, the light flashes properly... This means I have a short-circuit within the housing ???

Mystery solved; some "comedian" had swapped the ground and positive wires... Found out by using my multimeter! This is what was causing those burnt fuses, blown relay,...

Glad to see so many getting these issues resolved.
