An ignition scope can display maximum voltage by disconnecting one plug wire. Is this your target?

Well im going to replace pounts, condenser but was going to check coil just to eliminate problem of no spark at the plug. There is 12v to the coil
Thanks jim

You are already aware resistance tests are no longer valid in almost every instance, as they only work on a cool, or cold coil. The methods above are excellent, but not all have access.

A good auto parts store might well have an off vehicle electrical tester that will,run a coil,all the way to its operating temperature with an active spark test. They work well to test a coil.
