8. Turn switch to "Coil Test" position.
The coil meter should read steady and in the
"good" band.
NOTE: If coil tests "bad", reconnect posi-
tive tester lead as shown by dotted lines in Fig.
12-26, and readjust coil set regulator until
meter reads at set point 8, then retest coil. If
the coil tests "good", check primary circuit,
as described in Note 25. If the primary circuit
tests good, check the ballast register wire with
an Ohmmeter. Resistor value is 1.40 to 1.65
Ohms.
9. Now turn switch of Coil Tester Unit to
"Dwell-Ohm" position.
10. Connect red and blue leads of Coil Tester
Unit together as shown in Fig. 12-24, and, using
"Dwell-Ohm" regulator, adjust meter needle to
set line.
11. Disconnect red and blue leads and connect
leads as shown in Fig. 12-27.
12. The meter should be between 5,000 and
15,000 Ohms resistance.
NOTE: A high reading will indicate an open
or high resistance secondary winding while a
low reading will indicate shorted winding.
27. Condenser Tests
a. Preliminary Steps
The condenser has two important functions:
First, it aids in the collapse of the primary field,
and second, it prevents arcing and pitting of the
breaker points.
The condenser should be tested for:
1. Series resistance.
2. Correct capacity.
3. Maximum insulation breakdown resistance.
These factors are tested on the Condenser
Tester with one hook-up by turning the Selector
Switch to the proper position. First, however, the
meter should be calibrated:
1. Connect the Condenser Tester wire clips
together, Fig. 12-28.
2. Turn master switch ON.
3. Turn switch of Condenser Tester Unit to
"Microhm" position and allow unit to warm up.
4. Turn regulator knob until meter reads on set
line.
5. Leave in "Microhm" position and proceed
with Condenser Tests.

Microhm (series resistance) Tests
1. Remove distributor cap.
