NOTE

YOUR TRACTOR IS
EQUIPPED WITH A SPECIAL

BROWN

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

NON-REMOVABLE

CONNECTIONS

WILL BECOME THEIR BRIGHTEST.

NOTE: IF WIRING INSULATED CLIPS WERE REMOVED FOR

SERVICING OF UNIT, THEY SHOULD BE REPLACED TO
