ELECTRICAL-MECHANICAL TROUBLESHOOTING
(1997) DEPENDABLE CARE
(For more detailed checks of these and other conditions refer to service manual part
no. 16001145, Section 2.)
General Information
The malfunction of an electrical circuit cannot easily be diagnosed unless you first
understand how it functions when operating normally.
Components
There are two basic categories for electrical components, switches and loads.
A switch controls the current path to a load component. Door switches, water level
switches and relays are examples of switching components.
An electrical load uses electricity to perform some function. Motors convert electricity
to magnetic fields and then to mechanical motion. Solenoids use magnetic fields to
push or pull. Lamps convert electricity to light.
The schematic wiring diagram is followed much like a road map. The lines represent
the wiring connections between components. Connections in the wiring are indicated
by a small dot. If the lines cross but no dot is present at the intersection, there is no
connection. As much as possible, switches are shown in their normal position electri-
cally without actuation.
