STARTER SOLENOID

A.) Set the Start/Stop Switch to

START position and back to NEUTRAL

several times. An audible "click”

should be heard as the solenoid

actuates^

RESULTS: !.) Solenoid actuates, but

engine does not crank............................... Continue- ttst (Paragraph "B")

2.) Solenoid does not actuate,..Continue test (Paragraph "D")

B. ) Set VOM to "+DC" and to a scale greater than 12 Volts DC. Connect

the NEGATIVE (pr COMMON) test probe to. ground. Connect the POSITIVE (+)

test probe to the battery cable connection on the starter solenoid. The

meter needle should indicate 12 volts DC.

RESULTS: 1.) Meter reads 12 V o l t s C o n t i n u e test (Paragraph "C")

2.) Meter indicates less

than 12 Volts..............................................Check for open or shorted wire

or loose connections between

battery and starter solenoid

C. ) Connect POSITIVE (+) meter probe to starter cable connection on

starter solenoid. Connect NEGATIVE (or COMMON) test probe to ground.

Hold Start/Stop Switch at START - meter should indicate 12 volts DC.

RESULTS: 1.) Meter does not indicate

12 Volts.................................................Install new starter solenoid

2.) Meter reads 12 Volts and

solenoid checks good.......Continue tests in "Diagnostic

Flow Charts", Section 3

D. ) Set VOM to "+DC" so that 12 Volts can be read. Connect, meter POS

ITIVE (+) probe to one of the small terminals on the starter solenoid.

Connect the remaining test probe to ground. Meter should read.12. Volts.

With NEGATIVE (or COMMON) test probe still connected to ground, conn

ect POSITIVE (+) test probe to the other small terminal. Meter should

indicate 12 volts DC.

RESULTS.: 1.) Meter indicates 12. Volts

from BOTH small terminals

to ground............. Continue tests in. "Diagnostic

Flow Charts", Section 3

Meter does NOT read 12

Volts.........................................................Retest battery, 15 Amp Fuse

and Start/Stop Switch. Wlien

sure that these components

are good, and

volts is not

obtained from both small ter

minals, replace solenoid,
