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 – 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.

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.
