Service Manual

Sample Problem:
This 244 won't turn over. The customer parked it in the
garage and turned it off. When he tried to start it a week
later, he heard one click. After that , nothing would
happen when he turned the key.
We know it is a short circuit because we found the 25
amp fuse blown.
STEP 1. Interview the customer. Any
information we get will help isolate the
problem.
STEP 2. Isolate the suspect area.
Notice what we did to the wiring
diagram at right.
Highlight the suspect area on a copy
of the wiring diagram.
If the short was in the white wire, the
30 amp fuse would have blown.
If the short was between the battery
and the 25 amp fuse, we would have
melted these wires.
If the pink wire or electric clutch
shorted we would have blown the 15
amp fuse.
Eliminate all the black wires as
possibilities because they're
to go to ground!
