Sorry for the delay, but I have been kind of going solo
on this the past few days. Thanks for all, this one really
has me
1970 Roadrunner 440.
I checked all my connections & find nothing wrong. Chased what
seemed like a whole lot of nothing as everything far a I see is right.
I agree with less resistance at the ballast in "run"...
except for one thing. In "start" I should still see
12+ volts to the coil & I only am getting 8.
When I disconnect the "run" side of the ballast resistor,
hold the key in "start" with 2 extensions & a 3/8 deep socket
(wedged from the floor), I get full 12+ volts to the coil.
My ballast may be high and will order a few 1ohmer's, butI believe
it's something pertaining to the resistor, or the "run" side
of the resistor... which would include the ECU.
Also, with the "run" side of the ballast hooked up, the plug (see below)
does not fire in start or run, but does fire when I return the key
to the accessory position. With the "run" side of the ballast disconnected,
the plug fires in "start" as it should.
In case I did not mention, The number one cyl is in the fire position and I have
the #1 spark plug clamped to ground so I can watch it fire from in the car.
