CONDENSER CHECKING:
- Check for external damage
- Check condenser efficiency with tester.
CONDENSER REPLACEMENT (Fig 14).
- Unsolder wire from terminal ‘A’
- Remove wire from hole ‘B’.
- Remove condenser securing screw ‘D’.
- Reverse procedure for refitting.
NOTE - During soldering operations, remove terminal
‘A’ from screw in order to prevent damage to insulator.
2. CONVENTIONAL IGNITION SYSTEM
EXTERNAL COIL BV SERIES
On BV engines an external coil ignition system is fitted.
On this model the coil assembly is mounted on two pillars
cast on the cylinder (Fig 16).
NOTE - Attention should be paid to the routing of wires
and of HT lead.
The flywheel fitted to this system has the magnetic mass
located on the outside of the flywheel (Fig 17-B).
The technical advantages of this system are:
- More consistent spark at low rpm
- Fixed timing
- Adjustable air gap (set to 0.38 mm) - .015”
BREAKER POINTS
The points are accessible by removal of the flywheel
and adjustment is the same as the internal coil system
(0.5 mm .020”)
LAMINATION/FLYWHEEL AIR GAPS
To set air gap, proceed as follows:
- Set coil at maximum gap
- Position flywheel magnets B as per Fig 16
- Place a 0.30 mm gauge or metal strip of at least 100
mm in length across the magnets. (Fig 18).
- Rotate the flywheel to position the magnets opposite
the coil, slacken the coil securing bolts, following which
the coil should be attracted to the gauge; tighten the
securing bolts and remove gauge.
