Coil cable question
I just checked the resistance on the coil-to-distributor cable in my truck today (it's a 1986 with the 5.8 H.O engine) and according to my Hayne's manual that cable is supposed to have resistance of 5000 ohms per inch on a DuraSpark ignition system, wich I got. Since the cable is 14 inches it should have a resistance of 70.000 ohms, but my ohmeter claims the cable is only about 5900 ohms, but also according to my Hayne's manual an engine with a TFI-IV ignition, that cable should have a resistance of 5000 ohms per FEET. 5000 ohms per feet on a 14 inch cable, means that the cable, wich is about 1.16 feet, should have a resistance of about 5800 ohms, wich damn close to what I measured.
Any thoughts? And does it matter?
