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.
