Jim,
For starters, I assume that you are working on the TR3. I just had to pull
the steering column out of my Dad's '48 TR1800 which is very similar to the
TR3.
Not that I doubt you, but you're sure you got a SPDT switch and not a
Double Pull Double Throw switch? You only have 3 terminals on the switch,
right? If you have 6 pins on the back of the switch, you are using all
3 terminals in 1 row, and not going between the 2 rows of pins?

That is correct. Untill you get current flowing through the flasher. At
that point, the flasher's internal switch will heat up and open, turning
off the power out of the flasher. When the power is off, the flasher's
switch will cool off and make contact again. Thus allowing current to
flow once more. Consiquently, the turn signals will blink.

That doesn't really make any sense unless. Even if you had a bad switch,
then you should still have power on the middle post.
How you think it works is correct.
Usually you have to have the ignition switch in the ON (or run) position
for the turn signals to work.

And did you have power at the center pin of your new "turn signal" switch?
If not, then either your ignition switch was NOT in the run position, or
you have a bad flasher.

Now, if I read between the lines, you are saying:
1. that the turn signals were working in the past.
2. but the quit working.
3. you tried to by pass the flasher with the old turn signal, and ??????
(I assume that the lights didn't work?
