jwgarvey,

The coil is a Bosch Red Super Coil - I have not been able to find the spec for it- I was expecting something along the lines of 10.6 or higher, but the temp was around 40 degrees, so that would have reduced the resistance slightly.

Bosch red coil (0 221 119 030):

- primary (1, 15): measured 1.8Ω, specified 1.2Ω-1.7Ω

- secondary (1, 4): measured 12.9Ω, specified 7.2Ω-16.0Ω

Bosch resistor (0 2278 900 001):

- measured 2.0Ω, specified 1.8Ω

So according to the Bosch specifications, we are both within the standards :-)

alhbln,

Thanks for the specs on the Bosch coil. Interestingly enough I replaced the bosch coil with a Pertronix 1.5 OHM coil 40011 and the resistor with a generic 1.5 Ohm from Summit and the car showed an improvement in cold starting and idle stability - actually got the car to start on the second try at 40 degrees. I'll detail more of this in another thread on the Pertronix ignitor and the 1.5 ohm coil w/resistor vs the 3.0 coil w/out resistor.
