» 1.6.3 LOW COOLANT LEVEL SWITCH_____________ _
Should tlie .engine coolant level drop below tloe level
of’the high coolant temperature switch, it is possible
for the engine to overheat wltlaout automatic shut
down. To prevent such overheating without automat­
ic shut down, the engine has a low coolant level sen­
sor. If the engine coolant drops too low, the engine
automatically shuts down.
# 1.6.4 0¥ERSPEE0 SHUTDOWN______________ __
The DC control circuit board (inside control panel)
senses engine speed from the frequency of the
alternator AC output. Should the alternator output
frequency exceed approximately 72 Hertz (2,160
alternator rpm), circuit board action initiates an
automatic engine shutdown.
# 1.6.5 OVERCRANK SHUTDOWN________________
After 90 seconds of crank-rest cycles (while in Auto
mode], this function ends cranking if the engine
fails to start in that 90-second span.
