TESTING FOR “SHORTS” IN THE CIRCUIT

To simplify the discussion of shorts in the system, please refer to the following schematic.

Resistance Check Method

• Disconnect the battery negative cable and remove the blown fuse.

• Disconnect all loads (SW1 open, relay disconnected and solenoid disconnected) powered through the fuse.

• Connect one probe of the DMM to the load side of the fuse terminal. Connect the other probe to a known

good ground.

• With SW1 open, check for continuity.

continuity; short is between fuse terminal and SW1 (point A).

no continuity; short is further down the circuit than SW1.

• Close SW1 and disconnect the relay. Put probes at the load side of fuse terminal and a known good ground.

Then, check for continuity.

continuity; short is between SW1 and the relay (point B).

no continuity; short is further down the circuit than the relay.

• Close SW1 and jump the relay contacts with jumper wire. Put probes at the load side of fuse terminal and a

known good ground. Then, check for continuity.

continuity; short is between relay and solenoid (point C).

no continuity; check solenoid, retrace steps.

Voltage Check Method

• Remove the blown fuse and disconnect all loads (i.e. SW1 open, relay disconnected and solenoid discon-

nected) powered through the fuse.

• Turn the ignition key to the ON or START position. Verify battery voltage at the battery + side of the fuse ter-

minal (one lead on the battery + terminal side of the fuse block and one lead on a known good ground).

• With SW1 open and the DMM leads across both fuse terminals, check for voltage.

voltage; short is between fuse block and SW1 (point A).

no voltage; short is further down the circuit than SW1.

• With SW1 closed, relay and solenoid disconnected and the DMM leads across both fuse terminals, check for

voltage.

voltage; short is between SW1 and the relay (point B).

no voltage; short is further down the circuit than the relay.

• With SW1 closed, relay contacts jumped with fused jumper wire check for voltage.

voltage; short is down the circuit of the relay or between the relay and the disconnected solenoid (point C).

no voltage; retrace steps and check power to fuse block.

GROUND INSPECTION

• Ground connections are very important to the proper operation of electrical and electronic circuits. Ground

connections are often exposed to moisture, dirt and other corrosive elements. The corrosion (rust) can

become an unwanted resistance. This unwanted resistance can change the way a circuit works.

• Electronically controlled circuits are very sensitive to proper grounding. A loose or corroded ground can

drastically affect an electronically controlled circuit. A poor or corroded ground can easily affect the circuit.

Even when the ground connection looks clean, there can be a thin film of rust on the surface.

SERVICE INFORMATION FOR ELECTRICAL INCIDENT

• When inspecting a ground connection follow these rules:

- Remove the ground bolt or screw.

- Inspect all mating surfaces for tarnish, dirt, rust, etc.

- Clean as required to assure good contact.

- Reinstall bolt or screw securely.

- Inspect for “add-on” accessories which may be interfering with the ground circuit.

- If several wires are crimped into one ground eyelet terminal, check for proper crimps. Make sure all of the

wires are clean, securely fastened and providing a good ground path. If multiple wires are cased in one eye-

let make sure no ground wires have excess wire insulation.

• For detailed ground distribution information, refer to “Ground Distribution” in PG section.

VOLTAGE DROP TESTS

• Voltage drop tests are often used to find components or circuits which have excessive resistance. A voltage

drop in a circuit is caused by a resistance when the circuit is in operation.

• Check the wire in the illustration. When measuring resistance with DMM, contact by a single strand of wire

will give reading of 0 ohms. This would indicate a good circuit. When the circuit operates, this single strand

of wire is not able to carry the current. The single strand will have a high resistance to the current. This will

be picked up as a slight voltage drop.

• Unwanted resistance can be caused by many situations as follows:

- Undersized wiring (single strand example)

- Corrosion on switch contacts

- Loose wire connections or splices.

• If repairs are needed always use wire that is of the same or larger gauge.

Measuring Voltage Drop — Accumulated Method

• Connect the DMM across the connector or part of the circuit you want to check. The positive lead of the

DMM should be closer to power and the negative lead closer to ground.

• Operate the circuit.

• The DMM will indicate how many volts are being used to “push” current through that part of the circuit.

Note in the illustration that there is an excessive 4.1 volt drop between the battery and the bulb.

Measuring Voltage Drop — Step-by-Step

• The step-by-step method is most useful for isolating excessive drops in low voltage systems (such as those

in “Computer Controlled Systems”).

• Circuits in the “Computer Controlled System” operate on very low amperage.

• The (Computer Controlled) system operations can be adversely affected by any variation in resistance in the

system. Such resistance variation may be caused by poor connection, improper installation, improper wire

gauge or corrosion.

• The step by step voltage drop test can identify a component or wire with too much resistance.

CONTROL UNIT CIRCUIT TEST

• When the switch is ON, the control unit lights up the lamp.

SERVICE INFORMATION FOR ELECTRICAL INCIDENT

INPUT-OUTPUT VOLTAGE CHART

• The voltage value is based on the body ground.
• *: If high resistance exists in the switch side circuit (caused by a single strand), terminal 1 does not detect battery voltage. Control unit

does not detect the switch is ON even if the switch does not turn ON. Therefore, the control unit does not supply power to light up the
lamp.

CASE 2

INPUT-OUTPUT VOLTAGE CHART

• The voltage value is based on the body ground.
• *: If high resistance exists in the switch side circuit (caused by a single strand), terminal 2 does not detect approx. 0V. Control unit

does not detect the switch is ON even if the switch does not turn ON. Therefore, the control unit does not control ground to light up the
lamp.
