NOTE: Perform the following tests with engine(s) not
running.
Compressor will not run
1. Testing mode switch (ignition switch in RUN posi-
tion).
a. Purple wire must have battery voltage. If not,
fuse is blown or wiring is faulty.
b. Brown wire must have battery voltage when
mode switch is held in THRU-TRANSOM po-
sition. If not, switch is faulty.
c. Gray wire must have battery voltage when
the mode switch is held in THRU-PROP posi-
tion. If not, switch is faulty.
2. Testing air pump (ignition switch in RUN posi-
tion).
a. Check that black wire, in terminal block, is
grounded to engine.
b. Brown wire in terminal block, must have bat-
tery voltage when mode switch is held in
THRU-TRANSOM position. If not, wiring is
faulty. If voltage is present, air pump is faulty.
Air pump runs - system inoperative
With air pump running, check hoses, fittings, sole-
noid, and relief valve for air leakage. Replace parts
as needed.
System operates but goes THRU-PROP after air
pump stops running
1. Check that air pressure is not leaking past sole-
noid. If so, replace.
2. Check that air pressure is not leaking back
through air pump. If so, replace check valve.
3. Check that air pressure is not leaking at air cylin-
der assemblies. If so, replace faulty ones.
System stays in THRU-TRANSOM mode, will not
go back to THRU-PROP mode
Gray wire, in terminal block, must have battery volt-
age when mode switch is held in THRU-PROP posi-
tion. If not, wiring is faulty. If voltage is present, sole-
noid is faulty.
