batterynegative [- orneg.] post).If incorrecgyconnected,
alternator won't charge battery. If thishappens, see your
Sears Roebuckand Co. (orSears Canada, Inc.)Sewise

Center.

2. Neverexpose engine ignitionsystemto battery power. If

battery cable or any live wire contacts ignition system
groundwire, engine ignitionsystem may be damaged.

3. Ifexternalbatterycharger is used, disconnectpositive(+

or pos.) cable frombattery to prevent possibledamage.

4. See battery manufacturer's instructions for service end

storage.
