Checking switches (Fiesta 4)

Sometimes faulty switches are the source of electrical faults. Ford uses different types of switches in the Fiesta, some of which have symbols on them. To check that they are working properly, you can use a test lamp with wires with needles attached to the ends that pierce the insulation and determine whether voltage is supplied to the wires being tested. Replace faulty switches only with genuine Ford parts.



SEQUENCE OF WORKS

1. Purchase a Fiesta electrical wiring diagram.

2. First of all, check whether voltage is supplied to the switch being tested. To do this, connect a test lamp to the wire by piercing the insulation of the corresponding wire with a needle.

3. Check if voltage is supplied to the switch being tested by repeatedly turning on the ignition or lighting.

4. Then check for the presence of voltage, which should be supplied when the switch is set to the appropriate position.
