H. Test Solenoid
For this, and all tests, the ground speed control lever
must be in neutral, the parking brake set, and the PTO
switch must be OFF. Unplug and secure all spark plug
wires. Read completely through the instructions before
performing this and all tests.
1. Disconnect the Green/Black & Black/Yellow plug (A,
Figure 27) and Blue/White plug (B, Figure 27) from
the small posts of the solenoid.
2. Connect a jumper lead from one small post to
ground.
3. Connect a jumper lead to the other small post and
then touch it to the positive battery post. The lead
may arch to the battery post–this is normal.
There should be a single audible “click” heard as the
solenoid engages and the engine should turn over. If no
click is heard, proceed to SOLENOID BENCH TEST. If
the solenoid clicks but the starter does not turn the
engine over, check the starter cable and the starter itself.
If the solenoid “clicks” rapidly or repeatedly, recheck the
battery and all connections for corrosion.
I. Solenoid Bench Test
Replace a solenoid that does not pass all of the following
tests.
1. Identify and remove all wires from the solenoid.
Remove the solenoid.
2. Set the VOM to the Ohms setting. Probe the small
posts of the solenoid (Figure 28). The VOM should
read less than 10 Ohms.
