Is a printed copy available?

A Norton parts supplier should be able to get the correct manual for you.
A parts book is also available although the parts are on the Andover Norton (ANIL) website:

Check this first

Remove the fuel tank and see if you can find a block of rubber with wires coming out of it.

This thing is a little time bomb Norton installed. This thing is nothing more than 5 straight through connectors in a single rubber block.

What happens after a few decades is the rubber crumbles and/or the metal sleeves split. This causes intermittant shorts and opens.

It can be replaced by 5 individual in-line connectors.

The Norton electrical system is not that complicated but Norton used cheap connectors.

BTW what sort of electrical problems are you having?
 
I am not sure of what problems i have. It seems the previous owner was in midsteam of installing new wires. There are several wires that are not hooked to any thing. our focus is to verify a postive ground and then understand what type of ignition we have.
 
One of my bikes is 1974 850 with the original wiring harness. The harness came with connectors for every posible accessory that was available for any norton of that year. This included the Interpol.

It has connectors for all accessories on a police motorcycle. Thus there are a lot of unused connectors on my bike.

I don't know if aftermarket wiring harnesses have all of extra connectors or not.

I guess what I'm saying is don't get all freaked out - yet.

The wiring to make the bike run is very simple. Then you can add the lights, horn and all the other stuff. I don't know how handy or experienced you are with electrical wiring.

It may be a good idea to join the Nations Capital Norton Owners Club. It's $20.00 / year but it'll get you lots of help from Norton owners in your area.

Here's a link: http://www.ncno.org/about.htm

Good luck and keep us updated on your progress.
 
Help ........we are pretty sure we have the boyer black box III and positve ground. The rubber cube is gone. We do not have spark at the plug. How do we know if the regulator is wired correctly? Is it not possible to trace the power from point to point?
 
How do we know if the regulator is wired correctly?

Do you have an aftermarket regulator/rectifier or the original wafer rectifier with a separate zener diode? The aftermarket electronic regulator/rectifier will be a box approximately 2X2 or 2X3 with leads directly to the rotor and stator in the primary.
 
If you are using the standard single phase alternator, the regulator/rectifier (Podtronics, Boyer, Tympanium, etc.) will have four wires. A red, a black, and usually two yellow. The red goes to a good ground, the black to the (-) battery, and the yellows to the green/white and green/yellow leads of the alternator stator. If the bike was converted to negative ground, then the black goes to ground and the red to the + side of the battery.

If the charging system has been upgraded to the three-phase system, you will have three yellow leads and three leads from the alternator.
 
It seems we have 3 phase. the Boyer palstic box has 5 wires and there are 3 yellow wires from the regulator to the alternator/stator. I am trying to follow th power with my meter. What would be a series of checks to trace the power? Thanks in advance
