Solenoid Voltage Test
1.
If necessary, see Testing Basics on page 18-15.
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
. 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
.
–
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.
