volts, check the battery and engine ground cables,
starter cable and the starter solenoid to determine
the low reading.
BATTERY AND ENGINE GROUND STRAPS
1. Connect the voltmeter positive lead to the
battery ground terminal, Figure 7.
FIGURE 7
2. Connect the voltmeter negative lead to engine
ground and a jumper to the frame.
3. With ignition off, crank engine and make volt
meter reading, (should not be more than .2).
4. If more than .2, check ground strap connections
from battery to engine. Replace defective ground
straps.
STARTER CABLE
1. Connect the positive voltmeter lead to the
"BAT" terminal of the starter and the negative
lead to negative battery post.
2. Crank engine again (ignition off). If the
voltmeter reading is more than .2, check
for loose connections or frayed cables.
STARTER SOLENOID
1. Connect negative voltmeter lead to "BAT" termi-
nal of starter solenoid switch and positive lead to
motor terminal of the solenoid switch, Figure 8.
2. Close the solenoid electrically to crank the
engine; and if the reading is more than .2
volts, replace solenoid switch.

AMPERAGE DRAW TEST
1. Turn battery starter test know to "off" position
and the voltmeter "selector switch" to the 15
volt position and connect test leads, Figure 9.
FIGURE 9
2. Press starter switch and crank engine for
approximately 15 seconds and note the
"exact" reading on voltmeter.
3. Release Starter Switch and turn Starter-Battery
Tester knob clockwise until the voltmeter
reads "exactly" the same as when cranking the
engine. Ammeter reading should be 140 to
160 amperes (engine warm).
