ENGINE PROBLEMS

 

 

 

Engine will not idle down to low

1.

Make sure the Idler Switch (S4)

1. With the Idler Switch (S4) in the

speed. Machine has normal weld

 

is in the “Auto” position.

“Auto” position, check for the

output and auxiliary power.

 

2.

Make sure there is NOT an

presence

of 12VDC at

leads

 

 

#213 to

#215 located

at the

 

 

 

external load on the weld termi-

 

 

 

Idler Solenoid. If 12VDC is pre-

 

 

 

nals nor the auxiliary power

 

 

 

sent and

the Idler Solenoid is

 

 

 

receptacles.

 

 

 

not activating, then the solenoid

 

 

 

 

 

 

 

 

may be faulty or there is a

 

 

 

 

mechanical restriction prevent-

 

 

 

 

ing it from functioning.

 

 

 

 

 

2. If there is NOT 12VDC at leads

 

 

 

 

#213 to #215, then test for

 

 

 

 

12VDC from lead #213 to

 

 

 

 

ground (lead #5). See Wiring

 

 

 

 

Diagram. If 12VDC is present,

 

 

 

 

then check lead #215 for conti-

 

 

 

 

nuity (zero ohms) from the Idler

 

 

 

 

Solenoid to the Printed Circuit

 

 

 

 

Board plug 3J1. If lead #215 is

 

 

 

 

OK, then the Printed Circuit

 

 

 

 

Board may be faulty. Replace.

 

 

 

 

3. If there is NOT 12VDC from lead

 

 

 

 

#213 to ground (lead #5), then

 

 

 

 

check the Idler Switch (S4) for

 

 

 

 

proper operation and as-

 

 

 

 

sociated wires for loose or

 

 

 

 

faulty connections.

 

 

 

 

 

 

 

 

CAUTION

If for any reason you do not understand the test procedures or are unable to perform the test/repairs safely, con- tact the Lincoln Electric Service Department for electrical troubleshooting assistance before you proceed. Call 1-888-935-3877.
