Checking Cdi Unit - Suzuki PE250 Operating Instruction

megohm range; if not. use an ohmmeter capable of measur­
ing resistances of the megohm order. In either case, the two
testing prods,
(+)
and (-), are to be put to terminals of the
COl unit in reference to the chart below.
The COl unit has five terminals. The
(+)
prod or pointer is
to be put to one of the terminals listed in the top horizont­
al row, and the (-) prod or pointer to the corresponding
terminals listed in the vertical column. What the circuit
tester or ohmmeter should indicate for the two terminals ;s
given in the intersecting box (ON, OF F, CON or ABOUT 2
MEGOHMS).
The meanings of these terms are as follows:
Term Significance
ON
The tester shows circuit continuity.
OFF
The tester shows infinitely large resistance or,
for short, infinity.
CON
The indicating hand deflects a little but promptly
returns to the infinity end of the scale.
elements inside the COl unit will suffer rupture.
NOTE:
1. Before putting the probe pointers of the tester to two terminals,
touch the two with a jumper lead ¥l form a momentary short ­
circuit in order to neutralize the charges, if any.
2. For tha instrumant to be used, a circuit tester of the types
used by radio rapairmen will do. However, a high-grade circuit
tester or an ohmmeter is preferred.
3. If the instrument gives an indication other than what is shown in
the intersecting box in the chart for any pair of terminals, it
means that the COl unit is defective and needs replacement.
