Remove rings, bracelets, watches, necklaces,
and any other jewelry before working around
vehicle. Jewelry can catch on equipment and
cause injury or short across electrical circuits
and cause severe burns or electrical shock.
Use care when testing electrical connectors.
Do not damage connector pins or sockets
with multimeter probes. Failure to comply
may result in damage to equipment.
Inspect connector pins/sockets for damage,
corrosion, and serviceability. Check that
connector pins are not pushed back and
are capable of making good contact.
