Connecting to a No Coil Minus Ignition
SPARKWIRE CLIPS
Disconnect all Sparkwire Clips from the Spark Can except the middle lead. Connect it to the coil wire. If
the ignition system uses an internal coil, use one of the provided KV Plates.
PRIMARY AMPS PICKUP
Put the black Primary Amps Pickup around the wire that provides 12V power (B+) to the ignition module
and coil. You may hookup around the wire anywhere in the wiring harness, but be sure the pickup is
around the wire that carries
only the ignition pulses. The pickup label must face toward the battery plus
end of the wire (away from the coil).
SPARK PICKUP
The red Inductive Spark Pickup connects about the #1 cylinder plug wire. Connect close to the distributor.
The label on the Pickup should face the spark plug.
INDUCTIVE AMP PROBE
Connect the probe around the negative battery cable with the arrow pointing away from the battery, or the
positive battery cable with the arrow pointing towards the battery.
12V BATTERY LEAD
Connect the power leads to vehicles 12 volt battery. The connection must be made at the battery.
AUXILIARY LEAD
Not a required connection. Use the Auxiliary Lead for Sensor and voltage tests.
A No Coil Minus ignition is an ignition system where the secondary ignition coil is housed in the Distributor
Cap, and the coil minus lead is not accessible. Some Toyota and Nipondenso ignitions are of this type.
