Test Number 34C--Low Volt.ageIJropTests
in addition to the POINT RESISTANCE test described on page 20, this
position can be used to test the vehicle's electrical system for low
voltage drops. Set the Function Selector Knob to the POINTS LOW VOLTS
position.
Insert the BLACK plug into the BLACK OTHER TESTS socket. Read test results
on the 0-3.2 Volt scale. Each division on this scale is .I volt. This
scale has internal protection to prevent damage if the leads are accidentally
connected across full battery vol.tage. Use the GREEN and BLACK clips to
make the tests. The RED clip is not used.
Corroded or loose connections and frayed or broken cables can cause excessive
voltage drops in the starting circuit which can cause hard startlng, To
test for these conditions, connect the clips between I and 2, 2 and 3, 4
and 5, 5 and 6, 6 and 7, 7 and B, with the starter turning, Be sure the
high voltage lead is disconnected from the coll so the engine won't start.
During this test, no reading should be higher than .2 volts. If a reading
higher than .2 volts is observed during any of these tests, check the
cable or connections involved, clean and tighten the connections and
replace the cables or solenoid when necessary. If the meter reads to the
left of zero during any of the above tests, reverse the pos(tlon of the
clips.
