1950s 1956 front turn indicator lamps, exhaust noise

[J. Gomez]

Most probably I found the issue. I removed the pod from the car, took it home; I still had a short(or continuity) by connecting an Ohmmeter between the violet and blue wires. Was the short at the wiring or at the bulb? Removed the bulb and rechecked the resistance between both wire: it was now open, as it should. The resistance between both poles from the bulb was correct. By looking at those poles, I saw that one was marked just on the side. Most probably the contact into the socket was pushed and contacted the second one after some years.
After building a better tool to insert the bulb, I reassembled it, just to see that now there was some resistance value between both wires.
I'm attaching a picture from the tool; the bores at the soldered rods engage into the pins, allowing to control better the installation of the bulb.
Jose mentioned that this issue may be what I experienced; at first I did not think he was right...but I was wrong! Thanks Jose!
 

Roger,

Nifty tool you got there..!   

There are two major flaws with that type of socket since it's held by the three spring on the pins (just floating), one the two main contacts are not isolated inside the socket from each other so it is easy to get them cross while the bulb is twisting, and two you have to fight with the set of spring's tension from the main wire connectors and the ones for the socket.

Sometimes is easier to remove the reflector and pull it out so one can press the top (half-moon) the two closer pins to make the final 1/8 turn for the bulb to lock.

Well the main point is you are back in business with both fog and turn signal in service, so there is always a light after a dark tunnel. 

One Cadillac God disagreeing with another? Scandalous! Clay/Lexi

Since I had a bad experience with a 1044 bulb about 40 years ago, I never attempt to remove install such a bulb directly on the car. The tool I did relieved the pressure from the 3 springs, I just have to fight with the pressure from the springs under the wires.
I'm still wondering how they installed those bulbs at the factory. They had certainly special tools like a plier around the metal part of the bulb to install it.
