Disconnect battery -A- as per page 4.

Carry out the following procedures:

First unscrew battery earth terminal clamp -1- from battery negative terminal.

Then unscrew battery positive terminal clamp -2- from battery positive terminal.

If the battery positive wire is not tightened to the specified torque, there is a risk of the following:

• The battery -A- will not be charged fully.
• Vehicle electrics or electronics fail completely (breakdown).
• Danger of fires from sparks
• Damage to electronic components and control units due to excessive voltage

The specified torque for the nut -arrow- of the B+ wire is 15 Nm.

Check poly V-belt for:

• Sub-surface cracks (cracks, core ruptures, cross sectional breaks)
• Layer separation (top layer, cord strands)
• Base break-up
• Fraying of cord strands
• Flank wear (material wear, frayed flanks, flank brittleness – glassy flanks-, surface cracks)
• Traces of oil and grease

If faults are found, it is essential for the poly V-belt to be renewed. This will avoid possible breakdowns or operating problems.
