To run Lucas Rita kits on negative ground systems:
a) Instead of having black wire coming from AB11 amplifier connected to a 12V
negative power feed wire as in RITA diagram, this black wire should be grounded.
b) Instead of coil positive terminal being connected to ground as in RITA
diagram, this positive coil terminal should connect to 12V positive power feed
from switch.
c) All other connections in diagram remain the same.
(For 1979-87 Triumph twins with factory electronic ignition, the above
duplicates original wiring.)
If converting motorcycle to negative ground, please ensure the correct
rectifier and diode, or power control module (rectifier/regulator unit) are
being used, and they are properly installed. Also, ensure, of course, that
battery is properly installed with negative terminal grounded and fused. If in
doubt, please call BCS.
