Test performance of starter motor. Page 19 or 20. If
starter motor tests as specified, continue assembly.
HI-POTENTIAL TEST (HI-POT)
WARNING: A Hi-Potential Test of the 120 Volt AC starter
motor must be conducted prior to installation of starter
motor to engine.
DANGER: High voltage is used in this test. Exercise
extreme care to minimize the hazard of electrical shock.
If test equipment is not available, take starter motor to a
local electrical motor repair shop for test. Failure to
perform this test may present an electrical hazard. If
starter motor tests are positive, continue assembly.
