nections, melt fuses and LEDs" on page 157.
1. Release a battery cable from the battery.
2. Remove the panel with the cover under
switch panel.
3. Mark up the cable harnesses under the
distribution box, so they are assembled
in the same position.
4. Remove the plate, holding the rubber
grommets for the cable harnesses.

nections. Some connections have mark-
ings on the cables. Supplement if
necessary when the connections have
been disconnected. All outlet sockets on
the circuit board are connection marked.

cuit card. Use bent round nosed pliers to
press in the plastic catches holding the
connections.

plastic catches on each switch must be
pressed in.

Press on the bearing shield when tightening the belt.
IMPORTANT INFORMATION
It is important to check the circuit outside
of the circuit board first, to ensure this is
correct, before replacing the circuit board.
Partly due to cost, but also so that no exter-
nal fault can damage the new circuit board.
