Ducati gave up on Blitish eklectrickery , and used BOSH or Jap. stuff .
The Switchblocks relly need the contacts inside inspecting for degeneration .
Claening ( stoneing ) the contact points & seeing the tension is ok & the contacts mate is necessary .
Wiring Colour Code Table
Many British designed vehicles use colour coded cables to assist in identifying the various circuits in use. This is an extract from BS-AU7a 1983 Colour Code for Vehicle Wiring, from the British Standards Institution, 2 Park St., London W1A 2BS.
(Note that these colour codes may not apply directly to older cars. For example, the wipers on cars up to 1980 (at least) are not on a separate fuse circuit, so they are not orange, but green. Check the schematic for your car to be certain. - cak)

Er . . .
SEPERATEING to CHARGE / IGNITION / LIGHTING / & auxillaries gets it separate and comprehendable .
But I think we're degressing . To Fire it Up , You NEED the IGNITION - stuff all there - Coils to Points , and a Live Lead from the local
neuclear power station , or a battery . :wink:
Trailer Wie ( 5 and 7 core ) is often useable for the switchblocks , butll be the modern Euro Colour Code . :x Buts Still CODED ,
so isn't insurmountable . But if thyre all good up there , leave as be .
Most of the components like the H Lamp Switch & Ign Sw are common to 60s pommy cars ( junk yard stuff ) . Good place to purloin a
great pile of correctly colour coded wire & connectors , idiot lights & solenoids too .
Thought the Ign sw to pisspotical to persevere with , so tossed & fitted NEW & 10 3 Posn lock / switch . Those cheap ones are nasty - as fitted .
Looked at like a aircraft or ralley Car , you through in good main core wires , and follow through , one system at a time . When you need the Full Loom .
Were replacements ( original / ) for about $ 150 a while back . MkIIIs are NVT Era , common to T 160 ( electric start ) thus extra wires .
Some have the Cop wires included ( supurflous )
Any 69 to 75 loom should suit . a Bonneville one would even work , if the lengths match . The diagram may be more comprehendable .
I get the colour pencils out on the nasty black & white ones , for main wires .
Were ' standard ' clips & fittings ( wire end fittings ) freely available from pommy car suppliers ( Trade Supplyers )
The hideous Brass Bullets are good for gougeing 1/8 diameter trenches in the fingers - pulling the conectors when stuck .
ALL Spade Connections need cleaning & tweaking with plyers to get correct fit if ancient and osmosified & oxidiesed .
If its all bright and brassey in the back of the handlebar switchblocks they may be ok as is - with a good dose of C.R.C. etc .
Got a soldering iron ?? its a bit of a bind salveageing some fittings , but knocking up new points leads , and throwing on
a few wires will have it FIRED UP .
We wont get onto the Contact Breaker / auto advance ASSEMBLY . Yet . Same Proceedure . Strip Clean , square up . lube and set .
Some people fit solid state fit & forget ign triggers , for some reason . If you like working on steam trains you might enjoy setting up
the standard ignition .
Whatever , it wants ZERO innacuacies to blow off those Hondas . & Kawasakis's
:mrgreen: One Thing at a Time .
You don't need the key assy & lights to GO for a spin . A twisted join in Ign. Main will serve as a circuit break , as needs must .
Don't Even Need the Charge set up . Yet .
The 73 Mk 5 is pretty sorted ex factory , as theyed ditched the trashier tripe by then , so don't get despondent or discouraged .
That Milage its pretty much a once in a lifetime opportunity for us non millionaires . Particularly with a Know History .
Soo the MAIN THING is not to wreck anything . Diligant patience and perseverance will have it UNAPROACHABLE .
They were trying to make a expensive to produce machine at a affordable price , So you get the Core Unit & theres room to improve a few details . Like Fit 32 mm Dellorto Pumpers , if you hate mikunis or cant find Mk II AMALS . :twisted:
Blueprinted , or Electronic Ignition - and itll Haul the Coal .
Chuck us a photo of in the back of the switchgear , in colour - if you would ; and we'll decipher it .
If a chap cant afford ten Nortons , he can get to glare at a few here anyway . which is some consolation .
