the ground side of the circuit) and
connect the positive lead to the
positive (+) side of the circuit (to t he power source or the nearest power
source). Note that the negative voltme ter lead will always be black and
that the positive voltmeter will alwa ys be some color other than black
(usually red).
• Ohmmeter - the ohmmeter is designed to read resistance (measured in
ohms) in a circuit or component. Mo st ohmmeters will have a selector
switch which permits the measurement of different ranges of resistance
(usually the selector swit ch allows the multiplication of the meter reading
by 10, 100, 1,000 and 10,000). Some ohmmeters are "auto-ranging"
which means the meter itself will dete rmine which scale to use. Since the
meters are powered by an internal battery, the ohmmeter can be used
like a self-powered test light. When the ohmmeter is connected, current
from the ohmmeter flows through the ci rcuit or component being tested.
Since the ohmmeter's internal resi stance and voltage are known values,
the amount of current flow throug h the meter depends on the resistance
of the circuit or component being test ed. The ohmmeter can also be used
to perform a continuity test for suspected open circuits. In using the
meter for making continuity checks, do not be concerned with the actual
resistance readings. Zero resistance, or any ohm reading, indicates
continuity in the circui t. Infinite resistance indi cates an opening in the
circuit. A high resistance reading w here there should be none indicates a
problem in the circuit. Checks for s hort circuits are made in the same
manner as checks for open circuits, ex cept that the circuit must be
isolated from both power and normal gr ound. Infinite resistance indicates
no continuity, while zero resi stance indicates a dead short.
WARNING - Never use an ohmmeter to check the resistance of a component or
wire while there is volt age applied to the circuit
• Ammeter - an ammeter measures the am ount of current flowing through
a circuit in units called amperes or amps. At normal operating voltage,
most circuits have a characteristic amount of amperes, called "current
draw" which can be measured usi ng an ammeter. By referring to a
specified current draw rating, then measuring the amperes and
comparing the two values, one can det ermine what is happening within
the circuit to aid in diagnosis. An open circuit, for example, will not allow
any current to flow, so the amme ter reading will be zero. A damaged
component or circuit will have an incr eased current draw, so the reading
will be high. The ammeter is always connected in series with the circuit\
being tested. All of the current that normally flows through the circuit
must also flow through the ammeter; if there is any other path for the
current to follow, the ammeter readi ng will not be accurate. The ammeter
itself has very little resistance to curr ent flow and, therefore, will not affect
the circuit, but it will measure current draw only when the circuit is closed
and electricity is flowing. Excessive current draw can blow fuses and
drain the battery, while a reduced current draw can cause motors to run \
slowly, lights to dim and other components to not operate properly.

operation is required of it. Thus, little a
llowance for air circulation is required,
and the windings can be built into a very small space.
The starter solenoid is a magnetic dev ice which employs the small current
supplied by the starting switch circuit of the ignition switch. This magnetic action
moves a plunger which mechanically engages the starter and electrically closes
the heavy switch which connects it to t he battery. The starting switch circuit
consists of the starting switch cont ained within the ignition switch, a
transmission neutral safety switch or clutch pedal switch, and the wiring
necessary to connect these with the starter solenoid or relay.
A pinion, which is a small gear, is m ounted to a one-way drive clutch. This
clutch is splined to the starter armature shaft. When the ignition switch is moved
to the start position, the solenoid plunger slides the pinion toward the flywheel
ring gear via a collar and spring. If t he teeth on the pinion and flywheel match
properly, the pinion will engage the flywheel immediately. If the gear teeth butt
one another, the spring will be compressed and will force the gears to mesh as
soon as the starter turns far enough to a llow them to do so. As the solenoid
plunger reaches the end of it s travel, it closes the contacts that connect the
battery and starter and then the engine is cranked.
As soon as the engine star ts, the flywheel ring gear begins turning fast enough
to drive the pinion at an ex tremely high rate of speed. At this point, the one-way
clutch begins allowing the pi nion to spin faster than the starter shaft so that the
starter will not operate at excessive speed. When the i gnition switch is released
from the starter position, the solenoid is de-energized, and a spring contained
within the solenoid assembly pulls the gear out of mesh and interrupts the
current flow to the starter.
Some starters employ a separate relay, mounted away from the starter, to
switch the motor and solenoid current on and off. The relay thus replaces the
solenoid electrical switch, but does not eliminate the need for a solenoid
mounted on the starter used to mechanica lly engage the starter drive gears.
The relay is used to reduce the amount of current the starting switch must carry.
THE CHARGING SYSTEM
The automobile charging system provides electrical power for operation of the
vehicle's ignition and star ting systems and all the electrical accessories. The
battery serves as an electrical surge or storage tank, storing (in chemical form)
the energy originally pr oduced by the engine driven gen erator. The system also
provides a means of regulating alternat or output to protect the battery from
being overcharged and to avoid excess ive voltage to the accessories.
The storage battery is a chemical device in corporating parallel lead plates in a
tank containing a sulfuric acid-water solution. Adjacent plates are slightly
dissimilar, and the chemical reaction of the two dissimilar plates produces
electrical energy when the battery is connected to a load such as the starter
motor. The chemical reaction is reversible, so that when the generator i\
