rectly
CORRECTIVE ACTION
The battery must be installed with negative terminal attached to black ground wire. Negative terminal is
identified at the post by "NEG", "N" or "-". The positive terminal, identified by "POS", "P" or "+", must be
attached to the big red wire which goes to the solenoid.
Battery is dead or weak Check fluid level in battery. If fluid is low, fill to UPPER LEVEL line with water. Charge with taper
charger until fully charged.
Blown fuse or circuit
breaker
Replace fuse with 7-1/2 amp. automotive type fuse. Fuses seldom fail without a reason. The problem
must be corrected. Check for loose connections in the fuse holder. Replace fuse holder if necessary. A
dead short may be in the cranking or charging circuit where the insulation may have rubbed through
and exposed the bare wire. Replace the wire or repair with electrician's tape if the wire strands have
not been damaged.
Note: Look for a wire pinched between body panels, burned by the exhaust pipe or muffler or rubbed
against a moving part.
