Refer to Section 8 in service manual for Battery Specifications and Battery Installation.

DO NOT connect any electrical equipment directly to the motor's charging system. If the motor is run without a battery, the equipment could be damaged.

Use stop button to stop engine.

Test for proper operation of stator and rectifier/regulator. Refer to Running Test, Alternator Output, Section 8, in service manual.

If a tachometer is required, be sure to use only one of the recommended five pulse-type tachometers. Use of an incorrect tachometer will result in improper propeller selection and engine overspeeding. Engine overspeeding will result in serious damage to the powerhead.

To the New Owner

Always place terminal cove over end of positive battery cable whenever cable is removed from battery. Do not run motor with cable disconnected and unshielded against possible grounding. Electrical sparks and possible fire and explosion can occur.

DO NOT use wing nuts on battery connections even if they come with the battery. Wing nuts can loosen and cause errant warning signals of electrical system damage.

Keep the battery connections, clean, tight, and insulated to prevent their shorting or arcing and causing an explosion. If the battery mounting system does not cover the connections, install protective covers. Check often to see that connections stay clean and tight.
