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
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.
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 UTV 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 you purchase a new
electrical component(s), install it, and then find that the system still does not work properly, you will
probably be unable to return the unit for a refund.
Consider any test results carefully before replacing a component that teats only slightly out of
specification, especially resistance. A number of variables can affect test results dramatically. These
include: the testing meter's internal circuitry, ambient temperature and conditions under which the
GENERAL INFORMATION
An analog ohmmeter is useful when making
this type of test. Slight needle movements are
apparent when indicating a loose connection
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.
