Solid State Rectifier - Single & 3 Phase

Solid State Rectifier - Single & 3 Phase. The original plate-type rectifiers fitted to most British bikes are prone to failure due to vibration & corrosion. Solid state electronics offer a more robust solution with improved long-term reliability. This unit is a direct replacement for single phase plate type rectifiers. A pair of these units can used together when a 3 phase rectifier is required. Compact size (approx. 27mm x 27mm) allows for easy positioning, which should be on a small heat sink to aid cooling using the central mounting hole. Connection is straightforward.

Solid State Rectifier. No:49072A

Boyer Electronic Ignition. MkIII Ignition System - Electronic ignition allows you to feel confident that your engine is getting the sparks it wants when it wants them. MkIII kits consist of an Electronic Ignition Box, Stator Plate & Rotor. Fitting is straight-forward & detailed instructions are provided.  The stator & rotor replace your existing points plate. The advance/retard function is now handled electronically. This system has no mechanically contacting parts & uses solid state electronics. This ensures reliability, low maintenance & good sparking over long periods without adjustment. All kits come with a five year warranty. These systems fire all plugs together with ignition coils wired in series. For twins it is recommended to run 6 volt coils (CL6A) and triples should use 4 volt coils (CL4A).
