If the previous tests have not revealed a faulty
component it is necessary to check the alternator
output. If the alternator output is within specification
the inverter box is faulty and must be replaced.
Required tools to test the PowerLinkt system are:
• Digital Multimeter (2), Tool #19464
• PowerLinkt Test Box (1) #19528
• Torx Driver #19445
• Tachometer #19389 or 19200
CAUTION: Make all connections BEFORE
starting the engine.
1. Use Torx Driver #19445 to remove tamper proof
screws and the PowerLinktharness plug at the
inverter.
2. Install alternator harness plug into socket in
PowerLinkt Test Box #19528 (1), Fig. 38.
If the alternator output is LESS THAN 100 Volts,
replace the stator.
Fig. 38
3. Set Digital Multimeter (2) to read AC Volts.
4. Insert meter test leads into either receptacle in
test box.
5. Start engine. Set speed to 1800 RPM.
NOTE: DO NOT exceed 1800 RPM.
6. Press button on test box and note AC voltage.
Alternator output should be NO LESS THAN 100
Volts.
If the alternator output is 100 volts or HIGHER,
replace the inverter.
Anti-Afterfire Solenoid
The anti-afterfire solenoid is controlled by the
equipment ignition switch. With the switch OFF, the
solenoid plunger closes, stopping fuel flow through
the fixed main jet. With the switch in the ON and
START positions, the solenoid plunger opens,
allowing normal fuel flow. The solenoid is operating
properly if it CLICKS when the switch is turned ON
and OFF.
If solenoid does not CLICK, the problem could be the
equipment wiring, engine wiring or the solenoid. To
determine which is the problem, perform the
following tests in the order shown.
Solenoid Test
NOTE: The solenoid requires a minimum of 9 volts
DC to function.
1. Remove anti-afterfire solenoid from carburetor.
2. Place a jumper wire on either terminal of a 9 volt
transistor battery and on one of the pins in the
solenoid connector.
3. Place another jumper wire on the remaining pin
in the solenoid connector and on the other
terminal on the battery, Fig. 33.

Plunger should retract freely.
When battery connection is removed, plunger
should return.
Replace solenoid if plunger sticks or doesn’t move.
NOTE: Model 350400 with Mikuni carburetor:
With 9 volt battery applied to solenoid, apply
finger pressure to tip of solenoid. The tip
must be retracted manually approximately
0.030” (0.8 mm) before the solenoid will
energize.
