COURSE OF ACTION
ENGINE PROBLEMS
The engine goes to low idle but
does not stay in low idle.
1. Make sure there is NOT an
external load (auxiliary or weld)
connected to the RANGER 10-
LX.
1. The idler solenoid linkage may
be misadjusted or damaged.
2. The idler solenoid (L2) hold-in
circuitry may be faulty. Check
lead #214 for continuity (zero
ohms) from the solenoid to the
control board plug 5J1. See
Wiring Diagram. With the
Ranger 10-LX in the low idle
mode, check for 10 to 12VDC
from lead #222F to lead #214.
If the correct DC voltage is pre-
sent, the idler solenoid (L2) may
be faulty. If the correct DC volt-
age is NOT present, the control
board may be faulty.
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
