Test Procedure
Make sure red and black wires are connected to
12 V battery power supply.
Set voltmeter to 12 VDC scale. Connect test leads
to terminals “A” and “B” of TNT motor connector.
Use a wire jumper to alternately connect B+ to ter-
minals “1” and “2” of tilt and trim switch connector.
The meter must indicate battery voltage (12 V)
with B+ connected to either terminal.
Flywheel and Stator Ser-
vicing
IMPORTANT: Weak flywheel magnets can
cause low alternator output and affect outboard
performance.
An accurate test of alternator output can help
determine the flywheel’s condition. Refer to
Charging System Tests on p. 126.
