Connector Voltage
1. Measure the voltage with a voltmeter across the connector 30
(red) terminal and chassis.
2. If the voltage differs from the battery voltage (11 to 14 V), the
wiring harness is faulty.

Main Switch Continuity
1) Main Switch Key at OFF Position
1. Set the main switch OFF position.
2. Measure the resistance with an ohmmeter across the 30 terminal
and the AC terminal, 30 terminal and 50 terminal, 30 terminal and
19 terminal.
3. If infinity is not indicated, the contacts of the main switch are
faulty.
30 terminal – AC terminal
Resistance 30 terminal – 50 terminal
30 terminal – 19 terminal
2) Main Switch Key at ON Position
1. Set the main switch ON position.
2. Measure the resistance with an ohmmeter across the 30 terminal
and the AC terminal.
3. If 0 ohm is not indicated, the 30 – AC contact of the main switch
are faulty.
Resistance 30 terminal – AC terminal
3) Main Switch Key at PREHEAT Position
1. Set and hold the main switch key at the PREHEAT position.
2. Measure the resistance with an ohmmeter across the 30 terminal
and the 19 terminal, and measure the resistance across the 30
terminal and the AC terminal.
3. If 0 ohm is not indicated, these contacts of the main switch are
faulty.

4) Main Switch Key at START Position
1. Set and hold the main switch key at the START position.
2. Measure the resistance with an ohmmeter across the 30 terminal
and the 19 terminal, across the 30 terminal and the 50 terminal,
and across the 30 terminal and the AC terminal.
3. If 0 ohm is not indicated, these contacts of the main switch are
faulty.
