CAUTION
RECOMMENDED
COURSE OF ACTION
Make certain work clamp is tightly
connected to clean base metal.
Check for disconnected or broken
leads in idler sensing circuit.
Check generator output.
Replace P.C. Board with
known good one.
Check for proper connection of
leads.
Check for broken or loose leads
#5G and #253.
Check for disconnected or broken
leads in idler sensing circuit.
Idler may not function with less
than 100 to 150 watt load. Set
idler switch to high idle.
Replace P.C. Board with known
good one.
Check for proper connection of
leads.
Check for broken or loose leads
#5G and #253.
Replace with known good one.
Check the connection of the
lead from the voltage regulator
on the engine to the charging
ammeter and the battery.
Check and tighten connection
at battery, at starter, at engine
foot, or at frame.
Add fuel.
