Ignition Control Module

Power Transistor
Resistance Between Terminals:
a (+ lead) & b (- lead) no continuity
a (+ lead) & c (- lead) no continuity
b (+ lead) & a (- lead) some continuity
b (+ lead) & c (- lead) some continuity
c (+ lead) & a (- lead) some continuity
c (+ lead) & b (- lead) some continuity

NOTE: You MUST use a high quality (10 megohm impedance or more) DVOM for these tests. Be sure to follow the positive and negative lead instructions exactly as given. "Some continuity" is defined as any resistance between zero and infinite ohms.
