No spark?

OK, here it is....the CEI checklist right out of the service manual.

The test assumes a fully charged battery.

1. Measure voltage at coil "+" terminal with key "on".  It should be within one volt of battery voltage.  If not, suspect a problem with the wiring to the ignition switch, or the switch itself.
2. Measure voltage at the coil "-" terminal.  Result should be the same as at the "+" terminal.  If OK, go to step 3.  If not.... Disconnect the wire from the amplifier from the "-" post of the coil and measure voltage again.  Less than 2 volts means the coil is faulty.  More than 2 volts means the amplifier is faulty.
3. Disconnect distributor pickup coil from the amplifier (this is the harness from the distributor that plugs into the amp).  Measure resistance across the terminals.  It should be 2.2k to 4.8k ohms.  If OK, go to step 4.  If not, replace the pickup.
4. Reconnect the pickup to the amplifier.  Measure voltage at coil "-" post while cranking engine.  The voltage should drop.  If OK, go to step 5.  If not, the amplifier is faulty.
5. Check distributor cap and wires, distributor rotor arm, spark plugs and coil wire.
