2) Key Switch Key at "ON" Position
1. Set the key switch ON position.
2. Measure the resistance with an ohmmeter across the B terminal
and the AC terminal.
3. If 0 Ω is not indicated, the B - AC contact of the key switch are
damaged.
Resistance B terminal – AC terminal
3) Key Switch Key at "PREHEAT" Position
1. Set and hold the key 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 AC terminal.
3. If 0 Ω is not indicated, these contacts of the key switch are
damaged.
B terminal – G terminal
Resistance
B terminal – AC terminal
4) Key Switch Key at "START" Position
1. Set and hold the key switch key at the START position.
2. Measure the resistance with an ohmmeter across the B terminal
and the G terminal, across the B terminal an the ST terminal,
and across the B terminal and the AC terminal.
3. If 0 Ω is not indicated, these contacts of the key switch are
damaged.
B terminal – G terminal
Resistance B terminal – ST terminal
