Got it. Sometimes new doesn't always mean good. Specially with today's
parts made to lower standards.

Do you have spark at the plug wires when you roll it over?

If you have a tester, that will work, but if not there should be a snappy
blue/white spark that will jump to a good ground when you hold the wire

close to it. You could also use a spark plug and ground the body of it to
look. Any good plug will work for that.

Use an insulated tool to hold it, or you get to feel that spark!

If no spark, do you have battery voltage to the top of the coil when the
points are open? Does it drop to about half that when the points are closed?

The ammeter would indicate the points opening and closing as well, but I
find it hard to tell when the engine is turned over by a 12 votl battery.

Just turns too fast for the needle to react.

With the front mount distributor you could have a bad coil, or it could just be

a bad connection between the coil and the distributor.

Could also be a bad ignition switch not applying power to the coil.

So rather than throwing money at parts, we need to isolate it to the cause.

If I am correct. If I ohm out the ignition switch with it turned off I should get OL on my meter and if I turn key on it should read anything but OL. I will check switch tomorrow and also ohm out coil. When I bought coil it read 3.0 ohms. If it reads lower then it is bad right?
