I. Disconnect all tester leads. Use only the BLACK PLUG battery-dwell
lead for this test. Use the BLACK and GREEN test clip for voltage
loss tests.
2. Place function switch in POINTS position and read 3 volt points
scale. Each division is .I volt.
3. Disable engine to prevent starting by grounding HV iead of the coil
as shown below. On HEI or electronic systems disconnect battery
lead at coil or unplug distributor pickup coil connector.
4. Refer to starter system illustrated below. Connect GREEN and BLACK
clips across each section of circuit shown by numbers (i-2-3-4 etc.).
5. All readings must read .2 volts (2 div) or less for normal conditions.
Reverse test leads if meter reads backwards.
6. High readings will be caused by corroded or loose connections at
battery terminals, cables or a worn solenoid.
