Anyone know the primary resistance range of D585 truck coils? These would be GM part number 10457730 and the resistance measured between pin A and pin D.
I understand these need to be setup for low dwell time less than 3.5, and are not as preferred as the D581 coils. I have 16 of the D585 coils in my possession but not sure how I feel about running 20 year old coils on a high hp boosted setup. I was considering buying D581 new GM coils 19418993.
@clinebarger have you ever measured primary resistance from Pin A to Pin D on the D585 coils? Or secondary resistance from pin A to the coil output where it makes contact with the spark plug wire?
I understand that you can’t tell if a coil is working correctly based on resistance alone.
