Main Switch Key at OFF Position
1. Turn the main switch off.
2. Measure the resistance with an ohmmeter across the B terminal
and the AC terminal, B terminal and ST terminal, and B terminal
and G terminal.
3. If infinity is not indicated, the contacts of the main switch are
faulty.
B terminal – AC terminal
Resistance B terminal – ST terminal
B terminal – G terminal
Main Switch Key at ON Position
1. Turn the main switch on.
2. Measure the resistance with an ohmmeter across the B terminal
and the AC terminal.
3. If 0 ohm is not indicated, the B - AC contacts of the main switch
are faulty.
Resistance B terminal – AC terminal
Main Switch at START Position
1. Turn and hold the main switch key at the "START" position.
2. Measure the resistances with an ohmmeter across the B terminal
and the G terminal, and across the B terminal and the AC
terminal, and across the B terminal and the ST terminal.
3. If 0 ohm is not indicated, these contacts of the main switch are
faulty.
B terminal – G terminal
Resistance B terminal – ST terminal
B terminal – AC terminal
Main Switch at key PREHEAT Position
1. Turn and hold the main switch key at the "PREHEAT" position.
2. Measure the resistances with an ohmmeter across the B terminal
and the G terminal, and across B terminal and AC terminal.
3. If 0 ohm is not indicated, these contacts of the main switch are
faulty.
B terminal – G terminal
