HD-41404-C Harness Connector Test Kit

The HARNESS CONNECTOR TEST KIT (Part No. HD-41404-
C) contains pin and socket terminals and stackable banana
jack patch cords used to test circuits. The pin and socket ter-
minals are used to connect to various connectors used on the
vehicle. See the tool instruction sheet for specific terminal
usage.

NOTE

To prevent terminal damage while using the probe tips, insert
the probe tip straight into the cavity and keep it stable during
the test. Do not wiggle or move the probe tip once it has been
inserted into the terminal. Do not use more than one probe per
terminal or cavity at any one time.

HD-42682 Breakout Box (Instruments)

The BREAKOUT BOX (Part No. HD-42682) and BREAKOUT
BOX ADAPTERS (Part No. HD-46601) connect to the
speedometer [39]. Used in conjunction with a multimeter, it
allows circuit diagnosis of wiring harness and connections
without having to probe with sharp objects. Install breakout
box in series using the black connectors as follows:

Access the speedometer [39]. See the service manual.

See

Figure 1-33

DIAGNOSTICS AND TROUBLESHOOTING

VOLTAGE DROP

Voltage Drop Test

The voltage drop test:

•

Helps locate poor connections or components with
excessive voltage drops.

•

Measures the difference in potential or the actual voltage
dropped between the source and destination.

•

Checks the integrity of the wiring, switches, fuses, con-
nectors and contacts between the source and destination.

•

Identifies poor grounds.

A voltage drop test measures the difference in voltage between
two points in a circuit. The amount of voltage dropped over
any part of a circuit is directly related to the amount of resist-
ance in that part of the circuit.

Components such as wires, switches and connectors are
designed to have very little resistance and therefore very little
voltage drop. A voltage drop greater than 1.0V across these
components indicates a high resistance and possible fault.

The benefits of doing it this way are:

•

Readings are not as sensitive to real battery voltage.

•

Readings show the actual voltage dropped not just the
presence of voltage.

•

The system is tested as it is actually being used.

•

Testing is more accurate and displays hard-to-find poor
connections.

•

Starting circuits, lighting circuits or ignition circuits can be
tested with this approach. (Start from the most positive
and go to the most negative destination or component.)

When testing a typical power circuit, place the positive (red)
meter lead on the most positive part of the circuit (or the pos-
itive battery post). Remember, there is nothing more positive
than the positive post of the battery. Place the negative (black)
meter lead at the positive side of the connector in question.
Activate the circuit. Move the negative meter lead through the
circuit until the high voltage drop is found.

When testing a typical ground circuit, place the negative lead
on the most negative part of the circuit (or the negative battery
post). Remember, there is nothing more negative than the
negative post of the battery. Place the positive meter lead at
the negative side of the connector in question. Activate the
circuit. Move the positive meter lead through the circuit until
the high voltage drop is found.

The following steps demonstrate a typical starter circuit voltage
drop test:

Disconnect the fuel pump connector [86] to prevent the
engine from starting.

Connect the red meter lead to the positive battery
post.

Connect the black meter lead to the battery power
starter post on the starter and observe the meter
reading.

Crank the starter and observe the meter reading. The
difference in the voltage is the voltage drop.

See

Figure 1-41

. Move the black meter lead to the starter

side post of the starter solenoid. Crank the starter.

use BREAKOUT BOX (Part No. HD-48637) to simplify the
procedure. See

1.2 DIAGNOSTIC TOOLS

Set the multimeter to read voltage changes.

Start the motorcycle engine and run at idle.

Shake or wiggle the harness to detect intermittents. If
intermittents are present, radical voltage changes register
on the multimeter.

RELAY DIAGNOSTICS

Relay Variation

See

Figure 1-45

. Relays normally have four or five terminals.

The circuitry inside the relays are very similar with the exception
of the normally closed contact being eliminated in the four ter-
minal relay. Some relays have five terminals at the base, even
though internally 4 or 87A are not connected. See this topic
whenever a relay terminal is referenced in this manual to make
sure the proper terminal is being accessed.

A relay can be tested using the motorcycle's 12V battery and

Unplug the relay from relay block.

to energize the relay.

Connect relay terminal 85 to the negative battery terminal
and relay terminal 86 to the positive battery terminal.

2011 Touring Diagnostics: General Information 1-19

NOTE

Some relays contain internal diodes. If the applied voltage is
not the correct polarity, the diode could be damaged.

Test for continuity between terminals 30 and 87.

A good relay shows continuity (continuity tester lamp
on or a zero Ohm reading on the ohmmeter).

A malfunctioning relay will not show continuity and
must be replaced.
