Note:
It is possible, due to unfavorable tolerances, that the indicator lamp will indicate a faulty glow plug only after 2 glow plugs in cylinders 2 to 4 (or 5) have failed.

To make sure that the failure indication circuit is not defective, disconnect 2 glow plug leads of cylinders 2 to 4 (or 5) and repeat preglow procedure.

If the preglow indicator lamp indicates a fault (does not light up), the preglow time relay is in order.
