4. Electra tester
c. Connect fully charged battery to tester.
Turn on spark gap switch and increase gap
d
until misfire occurs.
Direct current resistance test.
2.
Use a pocket tester
meter to determine
tinuity of primary
windings.
1. Primary coil resistance value
2. Secondary coil resistance value
3. Ignition coil
E. Condenser test
If the contact points show excessive wear, or
the spark is weak (but the ignition coil is in
good condition), check the condenser.
1. Capacity test (use Electro Tester).

Standard values:
Primary coil resistance:
Secondary coil resistance:
a. Calibrate capacity scale.
b. Connect tester.
c. Meter needle will deflect and return to
center as condenser is charged. After
needle stops, note reading on "p F" scale.
Condenser capacity:
Insulation test.
Connect ohmmeter as shown (n x 1,000

Condenser
After this measurement, the condenser
tive lead wire to the condenser case.
