Troubleshooting
Tips and Precautions
Bef ore Troubleshootin g
. Check applicable fuses in the appropriate fuse/relay
box.
. Check the battery for damage, state of charge, and
clean. and tight connections.
. Check the alternator belt tension.
CAUTION:
. Do not quick-charge a battery unless the battery
ground cable has been disconnected, otherwise you
will damage the alternator diodes.
. Do not attempt to crank thc engins wilh the battery
ground cable loosely connected or you will severely
damage the wiring.
Handling Connestors
. Make sure the connectors are clean and have no loose
wire terminals,
. N4ake sure multiple cavity connectors are packed with
grease (except water-tight connectors).
. All connectors have push-down release type locks.
Some connectors have a clip on their side used to
attach them to a mount bracket on the body or on
another component. This clip has a pull type lock.
Some mounted connectors cannot be disconnected
unless you first release the lock and remove the con-
nector from its mount bracket.
LOCKINGPAWL ONOTHERHALF OFPulltodisengage
LOCKING TAB
CONNECTORBRACKET
Never try to disconnect connectors by pulling on
their wires; pull on the connector halves instead.
Alwavs reinstall olastic covers.
Before connecting connectors, make sure the termi-
nals are in place and not bent.
. Check for loose retainers and rubber seals.
RETAINER
The backs of some connectors are oacked with
grease. Add grease if necessary. lf the grease is con
taminated. reolace it.

Tips and Precautions (cont'dl
Insen the connector all the way and make sure it is
securely Iocked.
Position wires so that the open end of the cover faces
down.

Handling Wires and Harnesges
. Secure wires and wire harnesses to the frame with
their respective wire ties at the designated locations.
. Remove clips carefully; don't damage their locks.
Slip pliers under the clip base and through the hole at
an angle, then squeeze the expansion tabs to release the
clrD.
After installing harness clips, make sure the harness
doesn't interfere with any moving pans.
Keep wire harnesses away from exhaust pipes and
other hot parts, trom sharp edges of brackets and
holes. and from exoos€d screws and bolts.

T€sting and Repairs
. Do not use wires or harnesses with broken insulation.
Replace them or repair them by wrapping the break
with electricaltape.
. After installing parts, make sure that no wires are
pinched under them.
. When using electrical test equipment, follow the
manufacturer's instructions and those described in
this manual.
. lf possible, insert the probe of the tester from the
wire side (except waterproof connector).
. Seat grommets in their grooves properly.
. Use a probe with a tapered tip.
Refer to the instructions in the Honda Terminal Kit for
identification and replacement of connector termi-
nals.

Five-step Troubleshooting
1.
3.
Verify The Complaint
Turn on all the 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.
Analyze The Schematic
Look up the schematic for the problem circuit.
Determine how the circuit is supposed to work by
tracing 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 cause,
Based on the symptoms and your understanding of
the circuit operation, identify one or more possible
causes of the problem.
lsolate The Problem By Testing The Circuit
Make circuit tests to check the diagnosis you made
in step 2. Keep jn mind that a logical, simple proce-
dure is the key to efficient troubleshooting. Test for
the most likely cause of failure first. Try to make
tests at points that are easily accessible,
Fix The Problem
Once the specific problem is identified, make the
repair. Be sure to use proper tools and safe proce-
dures.
Make Sure The Circuit Works
Turn on all components in the repaired circuit in all
modes to make sure you've fixed the entire prob-
lem. lf the problem was a blown fuse, be sure to
test all of the circuits on the fuse. lvlake sure no new
problems turn up and the original problem does nol
recur.
