Test of Timer Relay
1. Remove the timer relay from the tractor.
2. Connect jumper leads across the battery positive terminal and
the timer relay terminal
3, and across the battery positive terminal
and the timer relay terminal
4.
3. Connect jumper leads across the battery negative terminal and
the timer relay terminal
2, and across the battery negative
terminal and the bulb terminal.
4. Connect jumper lead across the timer relay terminal 1 and the
bulb terminal.
5. The bulb lights up when disconnecting a jumper lead from the
terminal 3 arid goes off 6 to
13 seconds late, the timer relay is
proper.

Battery Charging Current
1. After starting the engine, disconnect the battery positive cord (+),
and connect an ammeter and voltmeter. Then switch on all
electrical loads (such as head lights) and measure the charging
current.
• NOTE
• Connect an ammeter only after starting the engine.
• When
the electrical loads is considerably low or the battery
is fully charged, the speCified reading may not be obtained.

Stator
1. Measure the resistance across each lead of the stator coil with
resistance range of circuit tester.
2. If the measurement is not within factory specification, replace it.
3. Check the continuity across each stator coil lead and core with
resistance range of circuit tester.
4. If infinity is not indicated, replace it.

Rotor
1. Measure the resistance across the slip rings.
2. If the resistance is not the factory speCification, replace it.
3. Check the continuity across the slip ring and core with resistance
range of circuit tester.
4. If infinity is not indicated, replace it.
