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 B terminal
and the ACC terminal, B terminal and ST terminal, B terminal
and G terminal.
3. If infinity is not indicated, the contacts of the main switch are
faulty.
B terminal – ACC terminal
Resistance B terminal – ST terminal
B terminal – G terminal
2) Main Switch Key at ON Position
1. Set the main switch ON position.
2. Measure the resistance with an ohmmeter across the B terminal
and the ACC terminal.
3. If 0 ohm is not indicated, the B – ACC contact of the main switch
are faulty.
Resistance B terminal – ACC 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 B terminal
and the G terminal, and measure the resistance across the B
terminal and the ACC terminal.
3. If 0 ohm is not indicated, these contacts of the main switch are
faulty.
