When current is flowing, never touch with
bare hand high tension cables or any other
parts with high voltage. If parts are moist,
touching them could cause an electric shock,
even if they are insulated. Always wear dry,
well-insulated gloves or wrap affected parts
with dry cloth before handling.

NOTE:
1. When performing the following
tests, use a multitester which can
measure accurately in the following
ranges; 0 to 20V D.C.; 0 to
1,000Ω;0 to 10V A.C.;0 to
50,000Ω.
2. If possible, start the vehicles and let
it run for 5 to 15 minutes with the
hood closed. This will bring all com-
ponents to normal operating temper-
ature, and will make it easier to
diagnose intermittent problems.
3. It is not necessary to disconnect the
harness connectors when perform-
ing the tests which follow. Simply
insert the motor probes into the back
of appropriate connector cavity.
