SECTION 2 - OPERATION

Ignition Switch

The ignition switch has four positions:

Stop, 1 - When the switch is in this position, the following cab functions will operate: rotary headlight switch, brake lights, dome light, cigar lighter, horn, turn signals, dimmer switch, pin 2 of the 3-pin auxiliary connector, trouble light, and fuel gauge. These items are live with the ignition switch in the stop position.

ACC, 2 - When the switch is in this position, the following cab functions are live in addition to the items listed in number one above: seat, front and rear windshield wiper switches, front and rear windshield washer switch, radio, fan rotary switch, and air-conditioner switch.

Run, 3 - When the switch is in this position, the following cab functions are live in addition to the items listed in number two above: pin 1 of 3-pin auxiliary connector, electronic monitor select switch, electronic monitor acknowledge switch, electronic monitor rotary select switch, warning light bar, PTO switch (if equipped), differential lock switch (if equipped), engine fuel solenoid, tractor performance monitor, and ether cold start button.

Engine Start, 4 - When the switch is turned and held in this position, the engine will crank and start as long as the safety start switch circuit is complete. The following items will turn off momentarily when the switch is turned to the start position, but will be live again when the key is released and returns to the run position: radio, air conditioner, and fan control switch.

The switch has a starter protection feature built-in. If the switch is rotated to the start position, and then released to the run position, it will be necessary to rotate the switch to the stop position in order to make another attempt at starting the tractor. This will prevent accidental engagement of the engine starting motor when the engine is already running.
