Choke Circuit

Disconnect the white two-pin connector adjacent to the
steering post.
CHOKE VOLTAGE
 NOTE: The battery must be at full charge for this test.
1. Set the meter selector to the AC Voltage position.
2. Connect the red tester lead to the yellow wire; then
connect the black tester lead to the green/black wire.
3. Crank the engine over using the electric starter. The
meter must read 3.5-4.5 AC volts.

Brakelight Switch

The switch connector is the two individual single connec-
tors located beneath the left-front fender.
 NOTE: The ignition switch must be in the ON position.
VOLTAGE (Wiring Harness
Connector)
1. Set the meter selector to the DC Voltage position;
then turn the ignition switch to the ON position.
2. Connect the red tester lead to the green/yellow wire;
then connect the black tester lead to a suitable ground.
3. The meter must read battery voltage.
 NOTE: If the meter reads no battery voltage, trouble-
shoot the battery, fuse, switch, or the main wiring harness.
 NOTE: If the meter reads battery voltage, the main
wiring harness is good; test the switch/component,
the connector, and the switch wiring harness for
resistance.
RESISTANCE (Brakelight Switch
Connector)
CAUTION
Always disconnect the battery when performing resis-
tance tests to avoid damaging the multimeter.
 NOTE: The brake lever must be compressed for this
test. Also, the ignition switch must be in the OFF
position.
1. Set the meter selector to the OHMS position.
2. Connect the red tester lead to the black wire; then
connect the black tester lead to the green/yellow
wire.
3. When the lever is compressed, the meter must read
less than 1 ohm.
 NOTE: If the meter reads more than 1 ohm of resis-
tance, troubleshoot or replace the switch/component,
the connector, or the switch wiring harness.

The main (7 amp) fuse is located on the frame near the
battery under the seat.
 NOTE: To remove the fuse, compress the locking
tabs on either side of the fuse case and lift out.
If there is any type of electrical system failure, always
check the fuse first.
Always replace a blown fuse with a fuse of the same
type and rating.
Always disconnect the battery when performing resis-
tance tests to avoid damaging the multimeter.
1. Set the meter selector to the OHMS position.
2. Connect the red tester lead to one spade end of the
fuse; then connect the black tester lead to the other
spade end.
3. The meter must read less than 1 ohm resistance. If
the meter reads open, replace the fuse.
 NOTE: Make sure the fuse is returned to its proper
position according to amperage.
The ignition coil is attached to the upper frame behind
the left-side of the front fender panel. The coil can be
accessed inside the front-left fender well.
Always disconnect the battery when performing resis-
tance tests to avoid damaging the multimeter.
 NOTE: For these tests, the meter selector should be
set to the OHMS position.
PRIMARY WINDING RESISTANCE
1. Disconnect the black/yellow and green wires from
the coil.
2. Connect the red tester lead to one terminal; then con-
nect the black tester lead to the other terminal.
3. The meter must read less than 1 ohm.
 NOTE: If the meter does not read as specified,
replace ignition coil.
SECONDARY WINDING
RESISTANCE
1. Connect the red tester lead to the high tension lead
(plug cap removed); then connect the black tester
lead to a suitable ground.
2. The meter must read 2830-3170 ohms.
