MAINTENANCE AND ADJUSTMENT OF THE EV
81
a. Perform a continuity test as described in the appropriate service procedure. Or
under
Continuity Test
in this section
b. Lightly pull or wiggle the connectors while repeating the test. Do the same when
checking the wiring harness and individual components. especially where the
wires enter a housing or connector
c. A change in meter readings indicates a poor connection. Fine and repair the
problem or replace the part. Check for wires with cracked or broken insulation
NOTE
An analog ohmmeter is useful
when making this type of test.
Slight needle movements are
apparent when indicating a loose
connection
2. Heat
– This is another common problem with connectors or plugs that have loose or
poor connections. As these connections heat up. The connection or joint expands
and separates. Causing an open circuit. Other heat related problem occur when a
component creates its own heat as it starts to fail or go bad
a. Troubleshoot the problem to help isolate the problem or area
b. To check a connector. Perform a continuity test as described in the appropriate
service procedure. Or under
Continuity test
in this chapter. Then repeat the test
while heating the ground. If the lamp comes on. The problem is the connection
between the lamp and Connector with a heat gun or hair dryer. If the meter
reading was normal (continuity) when the connector was cold, then fluctuated or
read infinity when heat was applied, the connection is bad.
c. To check a component, wait until the engine is clod, then start and run the engine.
Note operational differences when the engine is cold and hot.
d. If the engine does not start, isolate and remove the component. First test it at room
temperature, and then after heating it with a hair dryer. A change in meter readings
indicates a temperature problem.
CAUTION
A heat gun or hair dryer will quickly
raise the heat of the component
being tested. Do not apply heat
directly to the ICM or use heat in
excess of 60
℃
(140
℉
) on any
electrical component. If available,
monitor heat with an infrared
thermometer.
3. Water
—when this problem occurs in wet conditions, or in areas with high humidity,
start and run the engine in a dry area. Then, with the engine running, spray water
related problems repair themselves after the component becomes hot enough to dry
itself.
Electrical component replacement
Most EV dealerships and parts suppliers will not accept the return of any electrical
part. If you cannot determine the exact cause of any electrical system malfunction. If
