3.3 Checking the Wiring/Voltage to the Starter Solenoid
Prerequisites  Charged battery
 Multimeter
Procedure Follow the procedure below to check the voltage to the starter solenoid.
1. Locate the starter solenoid. Check the connection of the white wire (a). It must
be clean and tight. If it is not, clean it and try starting the engine again. If the
engine does not start, continue.
2. Disconnect the white wire.
3. Place the key switch in the START position and measure the voltage between
the white wire and ground.
Is 10.0–12.5 VDC measured?
The procedure to check the voltage to the starter solenoid is now complete. If the
problem has not been resolved, see section Checking the Key Switch.
Yes ____ No ____
If 12V is available at the white wire and the engine doesn’t
crank, there is a problem with the starter solenoid or starter
motor. See the Perkins Engine Repair Manual.
Check the starting
system beginning with
the key switch.
