NOTE

YOUR TRACTOR IS

ALTERNATOR SYSTEM.

THE LIGHTS ARE NOT

CONNECTED TO THE

BATTERY, BUT HAVE THEIR

OWN ELECTRICAL SOURCE.

BECAUSE OF THIS, THE

BRIGHTNESS OF THE LIGHTS

WILL CHANGE WITH ENGINE

SPEED. AT IDLE THE LIGHTS

WILL DIM. AS THE ENGINE IS

SPEEDED UP, THE LIGHTS

WILL BECOME THEIR BRIGHTEST.

WIRING INSULATED CLIPS

NOTE: IF WIRING INSULATED CLIPS WERE REMOVED FOR

SERVICING OF UNIT, THEY SHOULD BE REPLACED TO

PROPERLY SECURE YOUR WIRING.
