A Starter-Motor Circuit:
Figure 1 shows a very simple diagram of an engine starter-motor circuit. If one day you turn on the ignition switch, push the start button, and nothing happens, this is the circuit diagram you will need. A complete engine wiring diagram would probably contain the same information, but it would also contain all of the meters , idiot lights, and alternator wiring, adding considerable visual confusion.
For the starter-motor circuit all you need to see are the:
- Battery switch
- Fuse between battery switch common terminal and engine panel
- On/Off switch
- Momentary start
switch - Wire from starting switch to solenoid
- Heavy positive cable from
battery -select common terminal to solenoid - Heavy negative cable from battery negative terminal to engine negative terminal.
If the engine won’t turn over, the problem probably lies somewhere in this diagram.
