ELECTRICAL SYSTEM
12-33
NOTE: If car has been subjected to wet
weather the tester will show out of the blue
band. Car wiring must be dry.
1. Disconnect positive cable from battery post,
2. Disconnect lead at generator "BAT" termi-
nal to prevent damaging diodes.
3. Turn off all switches, and close all doors
to prevent operation of courtesy light from door
switches. '
4. Turn tester master switch "On".
5. Connect condenser tester leads together and
turn switch to Megohm position. Adjust meter
to "Set Line" with regulator.
6. Touch battery cable to its battery post to
wind clock or disconnect clock for safety.
7. Connect condenser leads as shown in Fig.
12-53. Meter should read in Blue Meg band if
insulation in primary circuit is normal.
8. If tester reads out of the blue band after
disconnecting the clock, the short in the primary
wiring circuit may be located by disconnecting
the battery (positive) wire at each of the following
units in turn:
Stop Light Switch
Courtesy Light Switches
Horn Relay and Wire
Starter Switch

45. Engine Tests
Engine tests include the inspection, testing
and adjustments of the various components of
the engine and engine accessories. These various
tests have been covered in detail in this section,
or other sections, and only a reference to the
note number will be made.
1. Inspect and test battery. This includes visual
inspection, light load test, or full charge hydro-
meter test as outlined in Notes 2, 4 and 6.
2. Inspect and test starting system. This in-
cludes lubrication, inspection, starting motor cir-
cuit resistance test and amperage draw test on
starting motor, Notes 10, 11 and 12.
3. Inspect and adjust distributor contact points
as explained in Note 19.
4. Make certain engine idle rpm is correctly
adjusted to 480 rpm in "Drive", Section 10,
Note 26.
5. Inspect and test performance of generator
as outlined in Notes 29-33, 36 and 39.
6. Test regulator for proper performance as
explained in Notes 40 and 42.
7. Check ignition timing, Note 23.
8. To provide an indication of over-all per-
formance of entire ignition system, make second-
ary efficiency test, Note 24.
9. The fuel system should be inspected thor-
oughly. Clean all fuel lines, strainers and flex-
ible lines. The fuel filter strainer must be
replaced if plugged.
10. Check and replace carburetor air cleaner,
Section 2, Note 3c.
11. If carburetor is not functioning properly,
it should be overhauled, Section 10.
12. Test fuel pump for proper volume and
pressure, Section 10, Note 14.
13. Clean and set spark plugs, Note 28.
14. Test ignition primary circuit for excessive
voltage drop which would lessen secondary output
of ignition coil, resulting in hard starting and
poor performance, Note 25.
15. Test coil continuity and capacity for proper
performance, Note 26d.
16. Test condenser for series resistance, ca-
pacity and insulation, Note 27.
17. Check all water hoses and tighten clamps.
18. Tighten cylinder heads - 75 foot-pounds.
19. Tighten intake manifold - four cap screws
to 30 foot-pounds and four nuts to 25 foot-pounds.
20. Adjust generator belt tension to proper
tension, Note 39.
