Fig. 11-24 Coil Secondary Test
1. Series resistance.
2. Correct capacity.
ENGINE ELECTRICAL
4. Connect leads as shown in Fig. 11-24.
5, The meter should read LESS than 20,000
OhMS resistance, A reading of more than 20,000
OHMS indicates a BAD coil,
e. Coil Capacity Test
determines whether or not the coil is
for vehicle operation when used in
with the Coil Secondary Continuity
1, Turn the Voltage Selector Switch of the Coil
Tester to 12 volt position.
2, Disconnect the distributor primary lead and
Tach Dwell lead if used, preferably at the coil as
shown in Fig. 11-25.
3. Turn on ignition switch,
4. Remove high tension lead from coil.
5, Connect tester leads as shown in solid lines,
Fig.
11-25 to
include ballast resistor
in test
circuit,
6. Turn switch of Coil Tester Unit to "Coil Set"
position, and adjust Coil Set Regulator until meter
reads at set point 8.
3, Maximum insulation breakdown resistance,
7, Turn switch to "Coil Test" position. The coil
meter should be steady in the GOOD hand.
These factors are tested on the Condenser Tester
with one hook-up, by turning the Selector Switch
NOTE:
If coil tests BAD, reconnect positive
to the proper position. First, however, the meter
tester
lead as shown by dotted lines in Fig.
11-25 and readjust
Coil Set Regulator until
meter reads at set point 8, then retest Coil,
If the Coil now tests Good, check Ballast Resis
tor and resistor connections.
Ballast Resistor value:
1,40 to 1.65 Ohms.
8. Turn Tester Switch to "Secondary Efficiency"
position.

Condenser Tests
a. Preliminary Steps
The condenser has two important functions: First,
it aids in the collapse of the primary field: Second,
it prevents arcing and pitting of the breaker points.
