In my ongoing quest to "fix"everything possible before I start rebuilding my webers, I figured I'd check out my coil today. I read an online article that said it's better checked out of the car, than in, and gave instructions that have me needing the resistance specs (which Haynes doesn't list).

Then, I started wondering why there was a spare (used) coil in the trunk. The Bosch coil currently in the car has two numbers on it. They are:

0 221 102 076
0 222 905 115

The spare coil lying in the trunk is:

0 221 119 009

Any insight here is appreciated as always...don't know what I'd do without y'all!

If it fits a 928, don't use it. It's made for Bosch electronic ignition, not points or aftermarket point replacement. The Cap'n

Thanks. Any idea where to find resistance specs on the stock coil?

Between 1 and 15 - 3.4ohm
between 1 or 15 and center 6.8kohm,
hence 2000 : 1 ratio, 12v in, 24,000 volts out -
and stay away from the 928 coil - that puts out around 50k - at least in my 928!!!
