SAFETY INTERLOCK CIRCUIT ON VEHICLE

SOLENOID
BATTERY
Figure 8-22. Battery Ignition Interlock Bypass.
~
WARNING: Never return an engine to the
owner with the safety interlock system removed or
bypassed.
Great bodily harm or equipment damage could
result.
Interlocks connected to an engine with a battery
ignition system are bypassed simply by placing a
jumper wire as shown in Figure 8-22.
~
WARNING: Make sure all safety conditions
have been observed before starting an engine with
the interlocks bypassed.
The safety interlock system on manual start mag-
neto ignition engines is placed in the ignition sys-
tem. The series connected interlock switches are
connected to a solid state module that is con-
nected to the ignition system. The module serves
two functions. It grounds the ignition system until
all interlocks have closed and, after the engine
has started, it prevents the ignition from grounding
as the individual interlocks are opened in normal
operation (transmission placed in Drive, PTO en-
gaged, etc.). Refer to Figure 8-23.
