And still another way to check a coil on the bench. Use a jumper
wires to connect the coil in a circuit with a new or known good
condenser, a new or known good spark plug and a known good
spark plug wire. Use a fully charged 12 volt battery. Connect
a common ground to the negative post on the battery.
1. Connect the positive (+) terminal on the coil to the positive (+) post on the battery.
2. Connect the wire on the condenser to the negative (-) terminal on the coil.
3. Connect the condenser body to common ground.
4. Connect the spark plug body to common ground.
5. Momentarily touch and remove the wire coming from the
negative (-) terminal on the coil and condenser to common
ground to simulate the opening and closing of the ignition
points. The coil should produce a strong spark at the
plug each time the wire is removed from common ground.
