- the metal base
- the capacitor
- the board 15.14.192 (if present)
- Disconnect connectors CN1, CN2 and CN3.
- Disconnect the cables fixed by means of nuts to board
15.14.254 (see point 8 and 9 in figure).
- Remove the fixing screw which can be accessed from the slot
below the capacitor (see point 10 in figure).
- Remove the fixing screw which can be accessed from the hole
below board 15.14.192 (see point 11 in figure).
- Remove the screw (see point 8A in figure).
To refit, carry out these jobs in reverse order.
IMPORTANT! When replacing the metal base,
ensure that you fit the plastic protection between
the rectifier unit radiator and the base itself.
IMPORTANT! When reconnecting cables no.22 and
no.23, make sure that you do not invert the red and
black cables! The red cable no.22 must be fixed to the
lower pc-board path and the black one no. 23 to the
upper pc-board path.

wrench set to 0.9 - 1.1 Nxm and weld the component
terminals.
- Re-connect the four connectors to the board and cables
no.22 and no.23 to board 15.14.254.
