FIRST THESE WORDS
The starter solenoid is actually nothing
more than a switch between the battery and
the starter motor.

The wires will be burned and the cut-out
switch will be burned and rendered useless.
Therefore, when installing
parts in the starter
marine installation,
obtain parts from a MARINE outlet to en-
sure proper service and to prevent damage
to other expensive components.
SAFETY WORD
Before making any test of the cranking
system, disconnect the spark plug leads at
the spark plugs to prevent the engine from
possibly starting during the test and causing
personal injury.
The following tests are to be performed
according to the faulty condition described.
