I . Verify The Complaint
Turn on allthe components in the problem circuit to
verify the customer complaint. Note the symptoms.
Do not begin disassembly or testing until you have
narrowed down the problem area.
2- Analyze The Schomatic
Look up the schematic for the problem circuit. De-
termine how the circuit is supposed to work by trac-
ing the current paths from the power feed through
the circuit components to ground. lf several circuits
fail at the same time, the fuse or ground is a likely
Based on the symptoms and your understanding ot
the circuit operation, identity one or more possible
causes of the problem.
3. lsolata The Problem By Testing The Circuit
Make circuit tests to check the diagnosis you made
in step 2. Keep in mind that a logical, simple proce-
dure is the key to efficient troubleshooting. Test for
the most likely cause of failure lirst. Try to make
tests at points that are easilV accessible.
4. Fix The Problem
Once the specific problem is identified, make the
repair. Be sure to use proper tools and safe
p.ocedures.
5. Make Sure The Circuit Workg
Turn on all components in the repaired circuit in all
modes to make sure you've fixed the entire problem.
lf the problem was a blown fuse, be sure to test all
of the circuits on that fuse. Make sure no new
problems turn up and the original problem does not
recuf.
