3. FUNCTION INSPECTION AND ADJUSTMENT
1. Battery
Disconnect the negative (–) battery cable at first and disconnect the positive (＋) battery cable.
WARNING: ALWAYS CHECK THE ELECTROLYTE LEVEL WITH THE TRACTOR ENGINE OFF, AS AN
EXPLOSIVE GAS IS PRODUCED INSIDE THE BATTERY WHEN THE ALTERNATOR IS
CHARGING. DO NOT USE AN EXPOSED FLAME AND DO NOT SMOKE WHEN CHECKING
THE BATTERY ELECTROLYTE LEVEL.
2. Fusible Link
A fusible link wire is used to protect the tractor’s entire electrical system. If too much amperage passes through this wire it
will melt down so that it will no longer allow current to pass (similar to the way a fuse works). The fusible link wire is a red
wire that goes to a connector that links into the main wiring harness.
3. Parking Brake Switch
The switch is normally close. The switch is closed at the
parking brake lever is locked position and is opened the
lever is released position.
a. Inspection
Use an ohmmeter to test the parking brake switch.
● With the button at the “OUT” position, there will
be continuity across the terminal leads.
● With the button at the “IN” position, there will be
no continuity across the terminal leads.
If test result are not outlined above, replace the
parking brake switch.

b. Adjustment
Using an ohmmeter and check to be sure the contacts open when the parking brake is released position, and closes
when the parking brake lever is the raised up position.
4. Alternator
Alternator provides current flow to the battery. See ”CHAPTER 2 ELECTRICAL UNIT”.
