Here is a quick test you can perform. Take everything off the negative Ign Coil Term. Install a jumper wire on that terminal. Turn on the Ignition Switch. With the opposite end of the wire, touch the motor block (ground) momentarily, if all is well, you should see a small spark at the end of the wire and spark at the Spark Plug.
OR.....
Take everything off the negative Ign Coil Term. Turn on the Ignition Switch. Take the black or negative meter lead and attach to motor ground. With the Red meter lead, if all is well, you should have 12V at both the positive and negative terminals of the Ignition Coil.
