How to set alternator on Boyer Bransden MkIII?
5) Set engine at 31 B.T.D.C. on the alternator mark (ensure correct mark is used – there are two marks on the alternator on 1972/3 models, use the mark indicating T.D.C. with the pistons in top position). 6) Fit magnetic rotor unit using one of the bolts (supplied), with the magnets in line with the “NORTON” name on the timing case. See Fig. l.

How does a Boyer Bransden ignition coil work?
18) Connect the black wire from the transistor box to the – terminal of the right-hand ignition coil. 19) Connect the white-blue wire (the one removed From the ballast resistor) to the white wire from the transistor box.
How to start a Boyer Bransden MkIII engine?
22) Refit tank, fuel lines and seat. 23) Start engine and time with a stroboscope to 31 B.T.D.C. (28 DEG. with standard ignition) with the engine running up to 5000 R.P.M. This is done by moving the ignition stator plate (Stator: clockwise to advance and counter-clockwise to retard) .
