SECTION 10F. STARTER
GENERAL
The repair of the starter is covered in the engine manu-
facturer’s service manual which can be obtained
through your local Jacobsen dealer/distributor.
FIELD TEST
Starter Motor Solenoid
1. Disconnect the NEG (-) battery cable.
2. Disconnect the RED lead from the coil and tape
the end (Figure 10F-1).
3. Connect the NEG (-) battery cable and turn the
ignition switch to the START position.
Each time the ignition switch is turned to the start
position, a click should be heard from the coil.
If no click is heard, the coil or electrical supply
may be defective. Continue with the next step.
4. Remove the PUR/WHT solenoid wire.
5. Set the multimeter to 20 VDC and connect the
POS (+) lead to the solenoid wire. Connect the
NEG (-) lead to a good ground.
6. Turn and hold the ignition switch in the start posi-
tion.
The multimeter should read the battery voltage
(Figure 10F-1).
If no voltage is measured, an open seat switch
(Section 10G), faulty wire (Section 10C), or igni-
tion switch (Section 10G) could be at fault.
