SPARKWIRE KV CLIPS
The capacitive sparkwire clips sense ignition
secondary voltage. Connect the center clip
to the Cylinder #1 spark plug wire.
The rest of the clips may be connected to
any cylinder.
The clips are made to fit 8 and 7 mm
sparkwire. The silicone grease provided (or
equivalent) is helpful for putting them on the
sparkwires and for getting good coupling.
The sparkwire clips are designed to be
sensitive, so it is important to separate
them to prevent picking up signals from
an adjacent wire.
Always connect the grounding clip to the
engine to reduce interference effects from
ignition defects. Failure to do so may result
in false readings.
FOR 10 AND 12 CYLINDER ENGINES:
An adapter kit is available for connection to
DIS engines with more than 8 cylinders. The
kit includes two "T" connectors and two
additional sparkwire KV clips. Use one kit
for 10 cylinder engines or two kits for 12
cylinders.
To use the adapters, connect one "T" to
any position on the KV Harness, except
Cylinder #1. Plug two Sparkwire KV Clips
into the "T" and connect them to any two
spark plug wires of the same polarity.
DISTRIBUTOR KV LEAD
This lead connects to the coil secondary wire
on distributor ignitions. It is provided to
simplify hookup and is used in place of the
DIS KV Harness. If desired, the center clip
of the DIS KV Harness may be connected to
the distributor coil secondary wire instead.
KV PICKUP PLATES
Pickup plates are provided for GM, Toyota,
and Nippondenso systems that have the coil
located within the distributor. To read KVs,
clip the appropriate pickup plate to the
distributor housing, attach a Sparkwire KV
Clip to the bar or post on the pickup plate,
and plug it into the Cylinder #1 position of the
KV Harness.
