output and auxiliary power.

2.

Make sure there is NOT an

of 12VDC at

leads #224D to

 

 

external load on the weld termi-

 

 

#214, located at the Idler sole-

faulty or there is a mechanical

 

 

 

restriction preventing

it from

 

 

 

functioning.

 

 

 

 

 

2. If there is NOT 12VDC at leads

 

 

 

#224D to #214, then test for

 

 

 

12VDC from lead #224D to

 

 

 

ground (lead #5). See Wiring

 

 

 

Diagram. If 12VDC is present,

 

 

 

then check lead #214 for conti-

 

 

 

nuity (zero ohms) from the idler

 

 

 

solenoid to the printed circuit

 

 

 

board plug 8J1. Also check the

 

 

 

idler switch (S5) and the associ-

 

 

 

ated leads.

See

Wiring

 

 

 

Diagram. If the above are OK,

 

 

 

then the printed circuit board

 

 

 

may be faulty. Replace.

 

 

 

 

3. If there is NOT 12VDC from lead

 

 

 

#224D to ground (lead #5), then

 

 

 

check the wiring to the engine

 

 

 

terminal block connection. See

 

 

 

Wiring Diagram.

 

 

 

 

 

 

 

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 216-383-2531 or 1-800-833-9353.
