Step 2:

Use a voltmeter to make sure you have power

to terminal (B) on the back side of the ignition switch in

the off position. If you don’t have power to terminal (B)

check the battery connections and the fuse in the red

lead.

Step 3

: With the ignition switch in the "run" position,

check to see if power has been transferred from

terminal (B) to terminal (A). Terminal (A) on the ignition

switch supplies power to the back of the PTO switch on

the purple lead and on to the brake switch on the

brown/yellow lead out of the brake switch on the red/

violet lead to the start light and to terminal (S2) on the

ignition switch and to terminal 86 on solenoid #2.

Terminal (A) also supplies power to terminal 30 and

terminal 86 on solenoid #1 and to the hour meter, and

the voltage sensor and sensor light. When the operator

is in the seat, power will transfer from terminal 30 to

terminal 67 and on to the front PTO switch, and on to

terminal 86 on the solenoid #2 in the yellow/red lead

and on to the cruise control switch. Power is supplied

to the fuel shut off solenoid from terminal 86 on

solenoid #2.

Step 4:

With the ignition switch in the start position,

power is transferred from terminal (S2) to (S1).

Terminal solenoid and goes to ground through the base

of the starter solenoid.

Clutch check out:

Remove the clutch lead to the

wiring harness and check the clutch with a VOM for

field resistance to see if the coil is good (3.0 - 3.9). If

bad, the resistance will be high or not at all.

Ignition switch check out:

Voltage check out in the

"off" position, check for voltage at terminal B. Voltage

should not be present on terminals A, S1, S2.

With the ignition switch in the "run" position, check for

voltage at terminals B, A, S2. It should not be present

on terminal S1.

With the ignition switch in the "start" position, check for

voltage at terminals B, A, S2, S1.

PTO switch check out:

The PTO switch is a push/pull

switch with straight across contacts. Power transfer

should be checked with a voltmeter. The switch

contacts should be checked with an Ohm meter with

the wire harness plug removed. The light switch is

similar to the PTO switch with only one contact.

Diode check out

: Diodes are checked with an Ohm

meter set on diode check, and should pass voltage in

only one direction. If a diode passes voltage in both

directions or not at all the diode is defective and will

need to be replaced.
