Not to second guess what you are doing, but, depending on how bad the wiring
is trashed, I would sort out the electrical shorts in the main harness
before I continued trying to run the engine. I have a healthy, natural fear
of fires that begin with electrical shorts after watching a freshly restored
LBC meltdown and catch fire about ten years ago due to a short in the
harness. In fact, last night as I tried to fire up my MGB/GT project for the
first time, I had my son stand by with fire extinguisher in hand just in
case. Better safe than sorry (especially when my TR6 is parked right next
to it).

Greetings all,
Here's my problem. I bought my Stag without hearing it run. I knew
there
was a pretty bad meltdown in the wiring harness. The wiring was
worked on,
but it was obvious the previous owner was unable to do anything
here.
I put 12V to the fuel pump, hooked up the disconnected red wire from
the
Lumenition Electronic Ignition module, and the engine fired right
up.
Sounded pretty good too!
All euphoria ended after a couple of minutes, as the engine just
quit.
Acted as if I turned off the key, as the tach dropped right down and
the
engine spun down to a stop. It died exactly like the ignition key
was
turned cut off. After a few minutes, the car starts right up, runs
for
anything from 3 to 10 seconds, and the same thing happens. The
engine stops
firing, the tach immediately drops, and the engine winds down and
stops. I
verified the coil is getting power as the engine stops firing.
This is my first Triumph with electronic ignition. This failure mode
sounds
exactly like what my Dodge truck did as it's electronic ignition was
dying.
How robust is the Lumenition electronic system? How do I test it?
My other thought is the wiring harness. There are lots of melted
wires, and
I have yet to sort things out. What I am thinking is there might be
a
melted wire in the harness that is not totally shorted, but after a
few
minutes of running, the wire heats up, and the short occurs. This
elusive
short somehow kills the engine. This sounds really far fetched to
me...
