STATIC TEST: CONTINUITY
1. Disconnect the magneto wiring harness connec-
tor.
2. Install the 4-pin magneto harness adapter (P/N
295 000 131).
3. Check resistance between the YELLOW/BLACK
and the BLACK wires of the 4-pin magneto har-
ness adapter. The resistance should be between
0.1 to 1.0 ohm.
4. Place either meter lead into the RED/BLACK
wire and note the resistance (same as step no. 3).
If the readings are out of specification, the stator
will need to be replaced.
STATIC TEST: INSULATION
1. Disconnect the magneto wiring harness connec-
tor.
2. Install the 4-pin magneto harness adapter (P/N
295 000 131).
3. Insert multimeter positive (+) probe to the
YELLOW/BLACK wire of the 4-pin magneto har-
ness adapter.
4. Ground the multimeter negative (-) probe to the
engine or the stator iron core and note the read-
ing.
5. Repeat test with the other BLACK and RED/
BLACK wires of the 4-pin magneto harness
adapter.
NOTE:
There should be no continuity (infinity) be-
tween the stator insulated coils and ground. If
there is a reading, the stator coils and/or the wir-
ing from the coils is grounded and needs to be
replaced or repaired.
DYNAMIC TEST
1. Disconnect the magneto wiring harness connec-
tor.
2. Install the 4-pin magneto harness adapter (P/N
295 000 131).
3. Connect test probes of the multimeter to the
YELLOW/BLACK and RED/BLACK wires of the
4-pin magneto harness adapter.
4. Set multimeter to Vac scale.
5. Start and rev engine to 3500 RPM. The obtained
value should be between 45 and 70 Vac.
6. Repeat test with the BLACK wire and either the
RED/BLACK or YELLOW/BLACK wires of the 4-
pin magneto harness adapter.
7. If the stator is out of specification, replace it.
BATTERY
Troubleshooting
Removal
All Models Except GTX RFI
Proceed as follows:
1. Disconnect the BLACK negative cable first.
2. Disconnect the RED positive cable last.
3. Remove the vent line from the battery.
4. Remove the holding strap(s).
5. Withdraw battery from watercraft being careful
not lean it so that electrolyte flows out of vent
elbow.
SYMPTOM: DISCHARGED OR WEAK BATTERY
CAUSE
REMEDY
1. Battery posts and/or
cable terminal
oxidized.
Clean and coat with
dielectric grease.
2. Loose or bad
connections.
Check wiring and
connector cleanliness,
damaged or short circuit.
3. Faulty battery
(sulfated, doesn’t
keep a full charge,
damaged casing,
loose post).
Replace.
4. 15 amp fuse(s) burnt
or faulty rectifier.
First check fuse.
If it is in good condition,
check rectifier/regulator.
5. Faulty battery
charging coil
(or stator).
Replace.
WARNING
Battery BLACK negative cable must always
be disconnected first and connected last.
Never charge or boost battery while installed
in watercraft.
