When checking spark, do not allow spark gap to exceed
0.125 in. (3.175 mm). Larger gap will cause excessively
high potential buildup resulting in insulation breakdown
either internally or in ignition cable.
6. Test for spark as follows:
a. Disconnect ignition cable (1) from
igniter assembly.
Death or serious injury could occur if this equipment is not
properly grounded before connecting to a power source.
Do not attempt to operate before grounding. Always have
another person standing by who is trained in electric shock
first aid.
b. Disconnect fuel pump cable from EXTERNAL FUEL PUMP RECEPTACLE and close shutoff
valve at fuel container.
c. Position spring (2) at tip of cable not more than 0.125 in. (3.175 mm) from grounded
surface (3).
