1.
If necessary, see Testing Basics on page 18-14.
2.
Remove the electrical component box cover.
3.
Ensure that the wires are connected correctly and are tight. If they are not, rewire or tighten as necessary.
4.
Coil Side: Check resistance across the small posts of the solenoid. The reading should be 14 to 16 ohms. If
the reading is not within limits, replace the solenoid.
5.
Contact Side: Remove the 4-gauge white wire, the 10-gauge white wire, the 18-gauge red wire, and 18-gauge
white wire from the large post of the solenoid. Do not allow the wires to touch the frame or other components of
the vehicle (Figure 19-5, Page 19-8). Cover the other large post.
5.1. Place Forward/Reverse handle in the NEUTRAL position and neutral lockout switch in the MAINTENANCE
position.
5.2. Check voltage between the empty large post and ground (Figure 19-6, Page 19-8).
– With key switch in the OFF and ON positions: The meter should read no voltage.
– With key switch in the START position: The solenoid should click and the meter should read battery
voltage.
5.3. If the readings are incorrect, replace solenoid. See Solenoid Removal, Section 21, Page 21-3.
