1. ELECTRICAL TESTS
The test apparatus:
For the electrical tests, a multimeter must be used. This apparatus is used to test values,
resistances, voltages, currents, etc…
Before using this apparatus, carefully read the instructions supplied with it. Generally
speaking, the multimeter has a display window, a rotary knob for selecting the type of
measurement and range, and a set of sockets to select the ammeter range.

Reminder:
1. For measuring resistances, the item being measured must be disconnected from the
circuit.
2. For measuring voltage, the machine battery must be connected, the ignition on and the
multimeter connected in parallel with the equipment being tested.
3. For measuring current, the machine battery must be connected, the ignition on and the
multimeter connected in series with the equipment being tested.
Special cases:
Used as an ohmmeter:
1. When the two wires of the multimeter are in contact, the ohmmeter shows a value of
between 00.0
Ω
and 00.5
Ω
representing zero resistance If it does not, change the
multimeter battery.
2. When the two wires are separated, the ohmmeter shows by a special display (either
10.00 M
Ω
with the 1 which flashes, or ---- ) that there is no connection. This represents
an infinite resistance. (see apparatus instructions)
Note:
the ohm values of the coils are given for information and may vary from one
multimeter to another.
