SOLENOID ACTIVATED
1. Inlet (carburetor diaphragms)
2. Outlet to atmosphere blocked
3. Outlet to air intake silencer opened

TYPICAL
1. Solenoid
Up to 80% throttle opening, the solenoid is not
activated and the diaphragms of the carburetors
are opened to atmosphere.

When the diaphragms are opened to the air intake
silencer, the resulted vacuum moves the diaphragms, slightly leaning the mixture of the carburetors.

Throttle Position Switch
Disconnect the 3-wire connector housing from
the amplifier.
Using a 12 V battery and jumpers, connect the
POSITIVE to the connector housing RED wire
(POSITION A) and the negative to the connector
housing BLACK wire (POSITION B).
Using a voltmeter, connect the positive probe to
the RED wire (POSITION A) of the connector
housing and the negative probe to the BLUE wire
(POSITION C) of the connector housing.
The voltmeter should indicate 0 Volt.
Depress the throttle lever progressively. At 80%
to full throttle opening, the voltmeter should indicate the battery voltage. If not, replace throttle cable.

SOLENOID NOT ACTIVATED
1. Inlet (carburetor diaphragms)
2. Outlet to atmosphere
3. Outlet to air intake silencer blocked
From 80% to full throttle opening, the throttle position switch signals the amplifier. The amplifier
boost the signal to activate the solenoid.
The solenoid transfers the venting of the regulator
diaphragms from atmosphere to the air intake silencer (vacuum).
Amplifier
First, ensure the throttle position switch is in good
condition.
Disconnect the wiring harness (PURPLE and
BLACK wires) of the amplifier.
Using a 12 V battery and jumpers, connect the
POSITIVE to the amplifier PURPLE wire and the
NEGATIVE to the amplifier BLACK wire.
