Jerry,
I am no Dan Masters by any stretch... but when I read the TR4/A
circuit diagram on page 6-104 of the shop manual... the symptom
appears as if the hot battery input (green - pin marked B or
[1] ) is swapped with the turning lamp switch side (green/brown -
L or [3] pin).
If the flasher is working correctly... The middle pin on the
flasher going to the dash indicator (light green/purple - pin
P[2]) will reflect the same voltage as the green/brown on the
L[3] pin (marked L ). Figure 44 on page 6-124 shows the physical
layout of the flasher socket for reference.
Hope this helps rather than causing confusion. The flasher
operation could be tested at the workbench with a 12v source for
the B[1] pin and a bulb for the L[3] side. The voltage on the
P[2] pin could be read with a meter.

Subject: TR4A Signal Light Flasher
I have a problem with my signal lights on a TR 4 A. The problem
is that
while the front and rear lights flashed and signaled a right or
left turn;
the green indicator on the dash only worked occasionally and more
recently
did not work at all. The bulb is fine.
I assumed that the flasher was defective so I purchased a new
flasher unit
and installed it ( #550 three terminal unit and the same as I
pulled out).
Now the green bulb on the dash stays on all of the time but it
does flash
when I signal a turn. It goes off when the turn signal bulbs
flash on and on
when the bulbs flash off. Once the turn is complete and cancels
the turn
signal lever the bulb again stays on all of the time. I tried
this in the
parts store lot and went back in and exchanged the original
flasher unit I
purchased as I thought it was defective. The second unit they
gave me did
the same thing.
I drove home with a bright green light in my eyes wondering how
late the
Prince of Darkness stayed up dreaming up this little treat to be
dealt with.
Anybody have any ideas on how to put him to sleep.
