NOTE: Above readings are for a cold engine (room
temperature). Resistance will increase slightly, if en-
gine is warm.
3. If meter readings are other than specified, re-
place stator assembly.
IGNITION COIL TEST
IMPORTANT: Ohmmeter tests can only detect
certain faults in the ignition coil. Replace ignition
coil, if ohmmeter readings (listed in chart, follow-
ing) are not as specified. If coil tests OK, and coil
is still suspected of being faulty, use Multi-Meter/
DVA Tester (91-99750) or a voltmeter (capable of
measuring 400 volts DC, or higher) and Direct
Voltage Adaptor (91-89045) to thoroughly check
coil.
1. Disconnect wires from coil terminals.
2. Pull spark plug lead out of coil tower.
3. Use an ohmmeter and perform the following
tests.

* The primary DC resistance of these coils generally is less
than one (1) OHM. If a reading resembling a short is
obtained, this would be acceptable.
** Copper wire is an excellent conductor, but it will have a
noticeable difference in resistance from cold to hot
temperatures. Reasonable variations from these readings
are acceptable.
4. If meter readings are not as specified, replace
ignition coil.
TRIGGER TEST
1. Disconnect all trigger leads from switch box.
2. Use an Ohmmeter and perform the following
tests.

ADI Ignition using a RED
Stator with an Adapter
Module
Red stators require an adapter module that is con-
nected between the stator and switch box. Without
the adapter module, the voltage supplied by the sta-
tor would exceed the voltage capability of the switch
box.
