1. Disconnect the 6P connector (2) from wiper relay (1).
2. Turn the main switch to "ON" position.
3. Measure the voltage with a voltmeter across the connector
terminal c and chassis.

Wiper Relay Checking
1. Remove the wiper relay.
2. Connect jumper leads across the wiper relay, bulb (2) and 12 V
battery (3) as shown in the figure left.
3. When the jumper lead (4) is connected with terminal a, the bulb
