The primary inductive pickup cannot be in contact with, or its connecting wire be
crossing other engine electrical wires or stray RF interference may result.
The inductive pickups contain a fragile Ferrite Core that is sensitive to
engine heat and vibration. Do not drop the inductive pickup or snap the
pickup closed. Use extreme care in handling and placement of the
pickups.
1
Clip the primary inductive pickup to the primary wire of the coil opposite the
battery source.
2
Route the primary wire cable clear of devices that produce electronic noise.
Note:
You must ground the vehicle to the dyno for the electronics to function
properly. Refer to “Grounding the Vehicle” on page 5-9.
