hello, yesterday i fitted my 73 850 (positive ground) with a sparx 3 phase charging system. i have a battery tender plug wired directly to my battery, the newest wires on the bike, so i tied the black and red wire from the regulator into those. i disconnected all the wires from the rectifier, including the ground and also the zenor diode wire. the positive wire from the battery tender plug has a 7.5 fuse, which blew durring install. i replaced it with an 8 amp, fired it up. was charging plenty. my assimulator warning light now stays on (which worked fine) Also the 8 amp fuse blew after awhile. i stuck a 15 amp in and rode back to my shop. the battery was totally recharged in a short ride. is it a mistake to go through the fusable link from the battery tender plug? can i just use a 15 amp fuse? do i need to tie some of the wires from the rectifier together to complete the warning light circuit? obviously i am electrically challenged and any help is appreciated. thanks, jerome

I'm not sure that it's a mistake as such, but obviously the wiring really ought to be securely connected?

The Sparx three-phase alternator kit has a maximum output of 215 Watts @14V, which is just over 15 Amps (215W/14V = 15.3A) I don't know if the Amp output is regulated or not with the Sparx system, so that could be why the lower rated fuses blew?

I think you have to connect the Green/Yellow wire from the assimilator to (any) one of the stator output (AC) wires?

The Spax alternator box is a regulator and rectifier.

The Unapproachable Norton Commando

At the end of 1967 the Norton Commando was announced.

The Norton Commando was greeted with a certain amount of scepticism because on first sight the commando appeared to comprise of the old Norton Dominator twin cylinder engine mounted at an inclined angle in a set of new cylinder parts.

It was not realized that the new Norton Commando Isolastic method of engine suspension damped out all engine vibration and produced a machine which had uncanny smoothness for a vertical twin. In due course the critics were silenced and the Norton Commando had the distinction of being regarded as the first of todays so called superbikes. There can be little doubt that the original design concept of the Norton Commando has proved correct, since comparatively few modifications of any real consequence have been made since production commenced during 1968.

Now nearly 40 years later Norton Commando riders like us are a breed of our own, and as far as we are concerned its still more fun to go for a blat on the old Norton Commando, and fast. As a Norton Commando owner and enthusiast, my goal here is to promote and give credit to those who keep the Norton name going.

It is more deserving to give credit to the Commando itself, for after all these years it continues to be respected. The original Commando designers like John Favill are those who deserve the credit for developing this incredible motorcycle.

The Norton Commando Roadster and Interstate of the late seventies, never died. Although the Norton Villiers factory dispersed the tradition lived on. Today Kenny Dreer in the USA is developing the new 952 CC Norton. What a great looking bike this is, and its engineering is still based on the original layout. It will be interesting to see how the new 952CC Norton does in todays tough motorcycle market. One thing is for sure, I would own one if I could afford it.
