Electrical System? System!

If weâre doing what you are doing, Iâd be having a chat with Al Osborne, he can advise and supply everything for you to build your own loom, which would be the neatest way . Imho of course!

I would look at Vehicle Wiring Products' website. They will almost certainly have everything you need to build a loom as well as fuseboxes, sockets etc.

Just don't use those horrible pre-insulated crimp terminals!

Exactly, wise words above. Do not even think of using a loom off of another machine!! Most of the bits will be wrong and in the wrong place, by the time you've worked it out you could have wired three bikes! RED, BLUE-crimps forget them also. The Dizzy and advance curve are dictated by the engine. The Electronic 123 would be the best bet from those you mention as that has a totally self set advance curve via DIP switches.

The first thing you do is fit ALL the electrical devices. Nothing worse than finding half way through a rewire part is missing-'I'l leave the wires dangling, fit the 'switch later' then you find the switch is better else where, the wires are too short......A lot of my parts come from VWP anyway, but I will know what you want, VWP won't. I will be very happy to advise but suggest you go to my web site first and look at the Wiring Kit.

Diagram above is not too far from being ok. The main battery fuse protects most of the bikes wiring, switches etc but it does NOT protect from a fault in the reg/rect so the later wants feeding from after the fuse.

The ignition system if still for a twin but incoporates an electronic ignition will have different coil wiring and the inclusion of the amplifier.

And now in my humble opinion the above item described as 'some hi tecmethod' is a piece of tosh!

I always put an inline blade fuse in the earth connection to the battery as it's very easy to short the live terminal to earth with a carelessly wielded screwdriver etc. This makes a nasty smell and lets all the smoke out, and depending on layout causes mayhem in the loom.

For the power takeoff, use a Hella type socket as used on some BMWs rather than a cigarette lighter type as these are crude in the extreme.

Hmm, I have always wired bikes (professionally) so that any LIVE bits especially battery terminals cannot come to grief so for old British motorcycles the one main battery fuse is adequate. If you want to fit multi fuses it is up to you, perhaps it is a nice to have, but I can't see any need unless the wiring is poor, ie very tired or badly done, when odd fuse blowing can be a nuisance and could cause embarrassment with an ignition failure but leaves the lights on or vice versa, your choice.

Fine on power take off, the cigar lighter type are crude in the extreme.
