HOWTOPERFORM EFFICIENT DIAGNOSIS FORANELECTRICAL INCIDENT
Incident Simulation Tests
INTRODUCTION

Sometimes thesymptom isnot present whenthevehicle isbrought infor service.
If
possible, re-create
the conditions presentatthe time ofthe incident. Doingsomay help avoid aNo Trouble FoundDiag-
nosis. Thefollowing sectionillustrates waystosimulate theconditionslenvironment underwhich the
owner experiences anelectrical incident.
The section isbroken intothesixfollowing topics:
• Vehicle vibration
• Heat sensitive
• Freezing
• Water intrusion
• Electrical load
• Cold orhot start up
Get athorough description ofthe incident fromthecustomer. Itis important forsimulating thecondi-
tions ofthe problem.

VEHICLE VIBRATION

The problem mayoccur orbecome worsewhiledriving onarough roadorwhen engine isvibrating
(idle with
AIC
on). Insuch acase, youwillwant tocheck foravibration relatedcondition. Refertothe
illustration below.

Connectors
&
harness

Determine whichconnectors andwiring harness wouldaffecttheelectrical systemyouareinspecting.

Gently
shakeeachconnector andharness whilemonitoring thesystem forthe incident youaretrying
to duplicate. Thistestmay indicate aloose orpoor electrical connection.

Hint

Connectors canbeexposed tomoisture. Itis possible toget athin film ofcorrosion onthe connector
terminals. Avisual inspection maynotreveal thiswithout disconnecting theconnector. Ifthe problem
occurs intermittently, perhapstheproblem iscaused bycorrosion. Itis agood ideatodisconnect, inspect
and clean theterminals onrelated connectors inthe system.

Sensors
&
relays
Gently
applyaslight vibration tosensors andrelays inthe system youareinspecting.
This testmay indicate aloose orpoorly mounted sensororrelay.

HOWTOPERFORM EFFICIENT DIAGNOSIS FORANELECTRICAL INCIDENT
Circuit Inspection (Cont'd)
VOLTAGE DROPTESTS

Voltage droptests areoften usedtofind components orcircuits whichhaveexcessive resistance. A
voltage dropinacircuit iscaused byaresistance
whenthecircuit isin operation.

Check thewire inthe illustration. Whenmeasuring resistancewithohmmeter, contactbyasingle strand
of wire willgive reading of0ohms. Thiswould indicate agood circuit. Whenthecircuit operates, this
single strand ofwire isnot able tocarry thecurrent. Thesingle strand willhave ahigh resistance tothe
current. Thiswillbepicked upasaslight voltage drop.
Unwanted resistance canbecaused bymany situations asfollows:
Undersized wiring(single strandexample)
Corrosion onswitch contacts
Loose wireconnections orsplices.

If
repairs areneeded alwaysusewire thatisof the same orlarger gauge.

Measuring voltagedrop-Accumulated method

1. Connect thevoltmeter acrosstheconnector orpart ofthe circuit youwant tocheck. Thepositive lead
of the voltmeter shouldbecloser topower andthenegative leadcloser toground.
2. Operate thecircuit.
3. The voltmeter willindicate howmany voltsarebeing usedto"push" current through thatpart ofthe
circuit.

Note inthe illustration thatthere isan excessive 4.1volt drop between thebattery andthebulb.
Symptom: Dimbulb orno operation

Measuring voltagedrop-Step bystep

The step bystep method ismost useful forisolating excessive dropsinlow voltage systems (suchas
those in"Computer ControlledSystems").
Circuits inthe "Computer ControlledSystem"operateonvery lowamperage.
The (Computer Controlled) systemoperations canbeadversely affectedbyany variation inresistance
in the system. Suchresistance variationmaybecaused bypoor connection, improperinstallation,
improper wiregauge orcorrosion.
The step bystep voltage droptestcan identify acomponent orwire withtoomuch resistance.
