"ON-MOTORCYCLE" TESTS
Starter Relay Test
1.
See
Figure 5-5.
Locate starter relay. The relay is
attached to the frame near the oil tank's feed hose.
Unplug relay connector.
2.
To test relay, proceed to Step 3. If installing a new starter
relay, remove old relay. Secure new relay to frame using
screw and washer. Attach relay connector plug.
3.
See
Figure 5-6.
Obtain a 12 volt battery and a continuity
tester or ohmmeter. Connect positive battery lead to the
86 terminal. Connect negative battery lead to the 85 ter-
minal to energize relay. Check for continuity between the
30 and 87 terminals. A good relay shows continuity, con-
tinuity tester lamp "on" or a zero ohm reading on the
ohmmeter. A malfunctioning relay will not show continuity
and must be replaced.
4.
If starter relay is functioning properly, proceed to
STARTER CURRENT DRAW
Starter Current Draw Test
Check starter current draw with an induction ammeter before
disconnecting battery. Proceed as follows:
1.
See
Figure 5-7.
Verify that transmission is in neutral. Dis-
connect spark plug wires from spark plug terminals.
2.
Clamp induction ammeter over positive battery cable
next to starter.
3.
With ignition key switch ON, turn engine over by pressing
starter switch while taking a reading on the ammeter.
Disregard initial high current reading which is normal
when engine is first turned over.
Typical starter current draw will range between 140-
180 amperes.
4.
If starter current draw exceeds 180 amperes, then the
problem may be in the starter or starter drive. Remove
starter for further tests. See
page
5-11.

1.
Attach battery positive lead to 86 terminal.
2.
Attach battery negative lead to 85 terminal.
3.
Test for continuity between 30 and 87 terminals.
A good relay shows continuity or 0 ohms.
