Description: Please read the below information as this is "non-standard" fitment before ordering. This Boyer system is designed for points-controlled battery Ignition models fittedwith permanent magnet rotor alternators e.g. KH250, KH350, S1 & S2. H1 / H1A system which is an electronically controlled Battery ignition and fittedwith a wound rotor. The H1 system does not fire the Spark plugs via three coils,but supplies a timed current to just one coil which in turn fires the three plugs viaa distributor gear driven off the right-hand end of the crankshaft. The Boyer system is designed to fire all three plugs together every 120 Degreesof crankshaft rotation. It is this feature which makes the system suitable foradaptation to the H1 & H1A, as their single HT coil needs to discharge threetimes Every crankshaft revolution. ** A PDF. with the H1 & H1A instructions, and wiring diagram can be found on our website, on the "kit00062" product page. ** All ignition units come with a 5 year warranty.With over 40 years behind them, made in England, Boyer is considered by most to be "the choice" when it comes to electronic ignition systems.

Fitting up the brushes supplying the rotor windings preclude the use of Boyerstator plate and three pick-up coils. As a result, the H1's original signalGenerator and three-magnet S.G. rotor is retained. 2. The excellent circuit diagram shown on the kit's sheet of fitting instructionsshould be Followed, paying special attention to polarity. No alteration need bemade to the H1 wiring and it should be noted that the yellow wire from the newtransistor box must be Connected to a brown H1 wire to provide a controlledpositive supply. 3. The green and blue wires from the box must be connected to the yellow wireand screen Respectively from the H1 signal generator. 4. The positive terminal of the HT coil gets a supply from a brown H1 wire andthe negative Terminal is connected to one of the box's green wires via a diodewire supplied in the kit. 5. This leaves only a black wire from the transistor box which is connected toearth. 6. The box itself which is smaller than a cigarette packet can be convenientlysecured where the H1's unit previously resided using double sided sponge typetape which will provide excellent protection against vibration.** A PDF. with the H1 & H1A instructions, and wiring diagram can be found on our website, on the "kit00062" product page. ** Timing The systemTiming is done in the usual way, i.e., inserting a dial gauge in the Left-handspark plug hole and setting the piston at 2.94mm BTDC.Next align the mark on the S.G. rotor magnet projection with the mark on top ofthe pick-up coil housing.Note that 2.94mm is the optimum advance for engines with the newer increasedsquish Cylinder heads and shorter duration transfer port pistons.If your engine has the older cylinder heads and high cut-away pistons, then youmay wish to set your timing to the originally specified 3.45mm BTDC. ** A PDF. with the H1 & H1A instructions, and wiring diagram can be found on our website, on the "kit00062" product page. **
