STEP
Solenoid Testing: 'Hold in" Coil Test
PROBLEM:
STARTER SOLENOID DOES NOT ENGAGE WHEN TRANSMISSION IS IN "PARK" (NO SOUND WHEN KEY SWITCH IS TURNED.
Rae 8-22580
PROCEDURE
a. Using the same test circuit as in Step 4B, remove the test wire between the solenoid "M" terminal and ground.
b. Adjust the variable resistor until the voltmeter has a reading of 10 volts.
c. The ammeter must have a reading of 12.7 to 14.3 amps.
a. Pull the engine fuel stop control out. b. Make sure thatthe tractor transmission is in
"PARK" c. Install a jumper wire across the neutral start
switch wires. d. Turn the key switch to the start position. e. Check starter operation.
ENGINE STOP CONTROL "START"
RESULT
If the results are not to the specifications in part "c" of the procedure, replace the solenoid and
Go back to Step 1 B
a. Starter turns over engine: (neutral start switch problem)
I Continue to Step 5B I b. Starter does not turn
over engine:
Connect the switch wires again and
I Continue to Step 5C I

STEP PROCEDURE
Causes for neutral start switch problems: 1. Connections at switches have too much corrosion or are loose. 2. Switch ball has damage. 3. Switch shim adjustment not correct.
Checking "IGN" fuse: a. Connect one wire of a 12 volt test light to a
Rac 8-22580
good ground. b. Connect the other test light wire to one side
of the "IGN" fuse in the fuse panel. Check for test light illumination.
c. Move the test light wire connected to the fuse in part "b" to the other end of the fuse. Check for test light illumination.

STEP PROCEDURE
HIGH BEAM HEADLIGHTS AND FLOODLIGHTS CIRCUIT: a. Use the circuit diagram below to help find the problem. b. Check for bad fuses or bad light bulbs. c. Check for bad connections at the junction. d. Check for loose or bad ground connections. e. Check for broken wires. f. If floodlights are not working correctly and no problems in parts
"b" through "e", replace the floodlight relay for the bad circuit.
