Looks like my coil is still within spec...
According to the link you posted, a good coil should read between 0.4-2 ohms on the primary side, and between 6,000-15,000 on the output side.
My existing 35 year old Ford coil reads 1.3 ohms and 8,460 ohms.
The new aftermarket one I picked up today reads 3.0 ohms and 11,870 ohms.
Maybe I'll install the new one and keep the old one as a spare. I've been meaning to put together a little behind the seat kit with the old truck essentials...lol.
Sounds good!
IIRC the one on my Bronco was like 13K, a little high I thought. Put the new one on and no more cold start problem!
