ENGINE PROBLEMS
The engine will not crank when
the start button is pressed.
1. The battery may be
discharged. Check and if
necessary, charge or replace
the battery.
2. The battery cables or battery
connections may be loose or
corroded. Service the battery
terminals.
1. Check for battery voltage
where lead 50 connects to the
starter solenoid, while holding
in the start button.
• If no voltage is present, check
the connections and wiring
connecting the starter solenoid
and the start push button
switch. See Wiring Diagram. If
the wiring and connections are
good, replace the push button
switch.
• If voltage is present, check
that the negative battery
terminal is properly connected
to the engine block. If the
battery is properly connected,
the starter/solenoid is defective
and should be serviced or
replaced.
If for any reason you do not understand the test procedures or are unable to perform the test/repairs safely, contact the
Lincoln Electric Service Department for electrical troubleshooting assistance before you proceed. Call 1-888-935-3877.
