TESTING THE INDICATOR AND WARNING LAMPS
By turning ignition switch 20 to a special Test position it is possible to check whether certain lamps on the card for indicator and warning lamps are OK or not.

The Test position is situated between the Drive and Start positions.

When the ignition switch is turned to the Drive position, current (+15 circuit) is supplied via fuse 13 to the lamps that are to be tested (terminal 5 on the card for indicator and warning lamps).

When the ignition switch is then turned to the Test position, positive current continues to be supplied to the lamps at the same time as they are grounded via pin 1 of the main instrument display panel in that terminals C and C1 of the ignition switch are connected to each other.

The following lamps are connected in circuit during the test:
47f Warning lamp, brakes
47m Indicator lamp, handbrake
47r Indicator lamp, washer fluid level
