Jubilee project

Gary,

Welcome to the club. You have a nice challenge there. I suggest you get a good owner's manual. I think there might be one available from the club document repository. You really need a wiring diagram to see how things work together.

The alternator provides the power when the engine is running but you need a battery and voltage regulator to supply the coils that generate the spark. The points determine when the spark is produced for each cylinder. The alternator charges the battery.

Looking at your photos I would recommend in due course a new wiring harness (available from NOC shop) a modern voltage regulator and, if you can afford it, modern electronic ignition to replace the points.

Lots of help is available from members.

We like photos of the progress of the restoration as well.

Not the manual but very useful information from the club library. The Lightweights compendium.

Gary,

There were some changes during the life of the Jubilee so you need to know what year your bike dates from. If you don't know, the Records Officer will help you determine that from the frame and engine number.

See the 'Records' tab at the top of the home page.

Gary,

Electrically there is a number of questions to answer for your self at this point. If you are going to keep the bike and use it, 12V and electronic ignition would be best. If you just want to get it working cheaply then stick with 6V and originality. The original machine did NOT have a regulator (but it will need one for 12V). The original wiring loom is for 6V it can be used for 12V but several items will need changing. (or for 12V a fresh rewire is recommended I can supply the wiring). At this stage ignore the alternator. It is the last thing to worry about. But keep the two Wipac coils even for Electronic ignition. If you just want to 'get it going' then a carburettor would be a good start! Perhaps a petrol tank? Seeing its condition then road worthy is somewhere down the line. So having it running on a 6V battery 'on the floor' and a clipped on wire as an ignition switch is all you need to get it running.

Hi Gary

Welcome to the world of lightweight ownership! Where about are you in the world, there’s often a member nearby who you can chat to or even help!

The wiring loom looks home made so the colours may not be correct. At the vey least you need to check a wiring diagram and trace the path of each wire. Also, looking at the rust on the coil connections, you will need to clean each cable termination to get a good electrical contact. This is especially true of the battery connection to earth on the frame. If you have a multi-meter or a battery and bulb you should check that each wire is not broken inside the insulation by checking continuity. As Dan says help from a friend is a good idea and a second pair of hands will help.

Hi Gary,

I have spare Jubilee parts lists and manuals, albeit photocopies, available FOC.  You could use initially and then decide if you want to "upgrade".

As per Dan's comment above.  Where are you situated?

So I would connect the battery + to the brown wire on the coil in the picture and the battery negative to the blue on the coil Is that right? Not the way to go. The original wiring had a GREEN connection to both coils fed from the ignition switch, this could be the BLUE wire, this would be the battery negative (via a clip-becomes the ignition switch!) and the battery Positive goes to earth. There is no loom as such on this bike, just a few 'casual' wires, fine for a startup. BUT seeing the work involved and the condition is this recommended? How much water has been in the sump? 

Very important -removed the sump plate/filter and see what comes out? If it is mostly water based or serious sludge then do not run it, you could cause more damage. If it is mostly proper oil then maybe try a start.   Best of luck. (you'll need it!)

Hi, make sure ignition points are gapped properly and clean(points looks suspect in latest picture)as well as any wire ends where corrosion is evident. A prior picture shows corrosion on blue wire to upper coil. Good luck with the initial startup -Pat

You won't get Wipac ignition coils. Lucas (type) will have straight end terminals which are a nuisance under the tank. Spending money on coils at this stage is potentially a waste of money. Suggest an enquiry within the club if any ones has a Wipac 6V.

Stick with a pair or 6V Wipac if you can. Your last picture doesn't show any broken wires. But the Blue wire is still corroded, remove, and reconnect would be useful. 

The 6V coils on the Commando (and Bonneville) will do the job ok ( I sell them) but a new pair will cost you £50 at least. The Lucas coil has its HT terminal coming straight out it will work but the HT lead becomes awkward. Suggest you pursue a pair Wipac through the club or even flea bay. The Wipac was used on Bantams as well. can you 'bodge' the broken original, you won't want to use it on the road, just make a connection to the HT connection.

Item number 234717672452, untested and looks like it’s had a rough life. Good luck -Pat
