1980 Ignition Coil Resistances Off


New member
I read the resistances (ohms) for the cables from the distributor cap.
Two out of three of the Spark plug connectors were 1500 ohms when it should be 1000 +/- 400 (i think this is ok)
But!!! The Suppressor cable from ignition coil to distributor cap is 4000ohms!!! It should be 1000+/-400. Probably should replace that...
Rotor arm reading was fine.

Ignition coil readings were high too (28.10a for anyone with a bentley) Dont know if these really matter although the manual is telling me to replace it...
Terminal 1 to terminal 4 reads 3860ohms - suggested 2400-3500
terminal 1 and terminal 15 reads 1.5ohms - suggested 0.52-0.76

Are these worth replacing at these values?? Thanks!

Before spending a ton of $$ have you checked the same readings with a different DVOM? Does your vehicle have any drivability issues?
