NOTE
YOUR TRACTOR IS
EQUIPPED WITH A SPECIAL
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.
