Ignition Coil Specs for 20R, 22R, 22RE HERE-1975 to 1988
After recently suspecting my ignition coil was failing on my '78 20R, I went searching for "good" coils specs so I could test my coil with a volt/ohm meter. After much legwork I was finally able to locate a complete source for the ignition coil specs, so I decided to post them up here for reference. These charts cover coil specs for the 8RC, 18RC, 20R, 22R, 22RE, 22RE-T, 3VZ-E, F and 2F, and the 3F-E. Years covered are 1968 to 1988. I put 1975 to 1988 in the title as I know that's what most people will be looking for.
Here's the spec charts, plus diagrams on how to test both Primary Resistance and Secondary Resistance:
Primary Resistance Specs Primary Resistance Testing, + & - terminals on coil, ohm meter range 200. Secondary Resistance Specs Secondary Resistance Testing, - & center port terminals on coil, ohm meter range 20,000.
