This instruction will outline the installation of heated front glass for the machines that are listed above. The heated glass for the front window draws approximately five amps of power from the electrical system. The 5 amps can be supplied from a standard machine with an 80 amp alternator or from a machine with the 150 amp attachment alternator.
Note: If the heated right-hand door is also installed, the machine must have the 150 amp alternator due to the combined current requirements. The heated glass draws 5 amps, and the heated door requires 30 amps.
