Remove either of the coil primary wires and connect your meter in line between the coil terminal and the removed wire. With engine running you should have something like 3 or 4 amps draw reading. It will read a bit lower with higher revs. When you have done that report back. Regards, Kevin.
When you say 'either primary wire' does that mean either the one from the ignition circuit or the one from the coil to the distributor? I would have thought they'd be different after passing through the coil. I could get a multitester at Napa and give it a try. Then I guess I'm supposed to check the ohms across the coil too. I will surely have questions once I get the meter. Thanks
