0A-14 GENERAL INFORMATION
• When taking measurements at electrical connectors
using a tester probe, be sure to insert the probe (2) from
the wire harness side (backside) of the connector (1).
• When connecting meter probe (2) from terminal side of
coupler (1) because it can’t be connected from harness
side, use extra care not to bend male terminal of coupler
of force its female terminal open for connection.
In case of such coupler as shown connect probe as
shown to avoid opening female terminal.
Never connect probe where male terminal is supposed
to fit.
• When checking connection of terminals, check its male
half for bend and female half for excessive opening and
both for locking (looseness), corrosion, dust, etc.
• Before measuring voltage at each terminal, check to
make sure that battery voltage is 11 V or higher. Such
terminal voltage check at low battery voltage will lead to
erroneous diagnosis.
