OK.

The above-mentioned fault detection system operates by detecting an imbalance in the current to the #1 glow plug versus the current to the remaining plugs. If the connector is disconnected, there is no imbalance and, therefore, no fault is detected.

So does that mean that no glow plugs were burned out before (because the light came on normally)?
And it means that the system is still working, except with only 2 plugs instead of four? So all I should need are 2 plugs? If so, that's good to hear.
