I am hoping that I might lean on the list to help me confirm what I think is
the source of my problem with an electrical issue with my 74 Spitfire's turn
indicator circuit.

First a bit of background... a few weeks ago I was attempting to fix a fairly
long standing problem with my turn signal lights. The problem was that when I
turned my left indicator on my right indicator also came on (and vice versa),
but very dimly. I sourced what I thought was the problem to the turn indicator
switch and tried to clean that switch up. Unfortunately, instead of fixing the
problem (it is a long story with much cursing) I made the problem worse and
essentially shorted out the whole circuit. I think that this is referred to as
"shipwright's disease" :). Now I am not getting any power to the indicator
switch, and no power to the indicator flasher unit. I think I have sourced my
new problem back to my hazard flasher switch (I have the rocker hazard on my
car with the six prongs on the back).

I am no electrical genius, but after a few weeks of intermittent work on this
problem I have deducted from my work and my Haynes electrical diagram that
with the key in the on position (or with the car turned on and running) I
should have power coming from the hazard switch (actual location on the hazard
switch is the bottom drivers left prong on the hazard switch when installed in
the car - wire that connects to this prong is light green with a slate stripe)
to the indicator flasher unit and then to the indicator switch.

Right now I have no power coming from that prong and no power to the indicator
flasher unit etc.. I have thinking that in my original attempts to fix my
problem I may have burned out the connection that is made for the indicator
signal circuit in the hazard switch somehow.

However, since it really seems like a pain to remove the rocker hazard switch
I wanted to ask first if my thoughts made sense before going to the effort to
try to remove the hazard switch. While I am on that topic, any pointers (i.e.
easiest way) on how you remove the rocker hazard switch. I am thinking that
there must be either vertical or horizontal "clips" that lock the switch into
place into the dash.

Hope that makes sense. Any suggestions/insight from those with a bit more
experience in this area are welcomed.

Thanks,

That looks correct, according to the Mk. IV diagram at
triumphspitfire.com/images/wiring/MKIVwire.jpg

This may also help, as it seems to be functionally the same

I don't know when they went from rocker to pull switch.

Have you got power on the green wire going into the switch from the fuse?
