I have been having trouble finding a correct wiring diagram for my 76
tr6 USA spec.
The best I have found is a combination of the owners manual and the Bentley
manual, page 17. Number 43 is the E.G.R. warning light in the Bentley. It
isn't listed in the owners manual that I could see.
I have examined several sources only to find slight deviations in the
circuit on all.
What's your point? This is a Triumph we are talking about.
My car has 2 wires connected to the positive side of the ign coil, one is
the resiance wire as indicated on
several diagrams, and the second, I assume is a ballast resistor bypass wire
which should be 12v during cranking only, however I cannot confirm the
second wire on any wiring diagram. It is defiantly part of the original
wiring harness though.
You did not mention the color of the two wires, but the ballast resister
wire is pink and white. It comes from the white side of the ignition
switch. The diagram also shows a white with a yellow tracer. If these are
the two, all is right with the world. Look and see if the white/Yellow
connects to the starter. If so that is your 12V start boost.
I also have noticed that there is a bulb check function on the EGR warning
light which illuminates the bulb during
cranking. This also, does not appear on any wiring diagrams, as a mater of
fact, The EGR warning light is omitted all together.
Check item number 43 on page 17 of the Bentley manual.
I have checked the following diagrams already, Bentley manual 75-76,
Mitchell manual 75-76,
Haynes and Clymer. Have any of you come across an accurate diagram, I was
hoping that the Factory Service Manual would be accurate. Your help will be
much appreciated.
