Conversion To Alternator (2nd Time Around ) 1960

[whyperion]

With the 1960 Four Door Saloon, neatly at present with a new wiring loom (off the shelf with the relay for flashing rear brake lights as indicators ), but we didn't order up an alternator fitted loom, so understand there are some adjustments to be made ( my old Club magazine which detailed the conversion is somewhere in the flat, probably in the least accesible location, so questions of the day are- from the sticky diagram.

1) Ensure the battery is fitted -ve earth and remember to supply a sticky label somewhere to reminder to self and others.
2) Ensure battery clamps are correct size to fit over battery terminals/ Fish in the spare box for correct coloured terminal wires.
Q3) Do I need to reverse the wires conected to coil (CB and SW?)?

4) Realise that the crimp on terminals in electrical spares box are too large for the alternator, remember to find correct sized ones.
5) Removing F and D wires control box to now non existant dynamo straight forward, but can any of these act as the 'new wires' otherwise these will be taped up- alternative to run the bare ends into terminal block and connect where- I dont want to short-circuit things

Q6)New Cable Battery +Ve (off Solonid- to +Ve on Alternator rear) Any particulary colouring to use, and wire thickness- last time was white but I have a nice orange/yellow wire that looks good)
Q7)New Cable- IND (-ve of alternator)to IGN lamp. Again, size and colour preferences, I assume black as effectively this is the alternator earthing via the lamp- does this mean I now expect the IGN lamp to be permanently lit when IGN SW on? (thats what happen before, but is not the situation in current modern clio or older chevette?

It's NOT the 'alternator earthing' - so NO - the light will not be on all the time.

[whyperion]

Re-reading the diagram, of course its not an earth, (which is the alternator body), but Feed-LIght-Device Load ( one of the bits inside the alternator internal regulator.
Does not wholly explain why previously the 'auto-electrician professional' fitting led to the IGN light being permanently on.

[bmcecosse]

Because an LED would glow with only a tiny flow of current......and should NOT be fitted to the (so called) Ign warning light! The light glows dependent on current flow between the battery and the alternator - which will only happen if there is a voltage difference between the two. The LED would only light 'one way' and may not have passed enough current for the alternator 'sensing' if it is the type that requires sensing. ( It's really a 'generator not charging ' warning light....)

I think he said "fitting led" meaning fitting resulted in,not LED as in light emitting diode.

Garage decided that the alternator I had ( from my well deceased Austin 1300), was indeed, not charging (which probably was the reason the generator not working light was not going off and the reluctance to start), and supplied replacement alternator with kit and wired up somewhat differently ( and less neatly to how I had ), I'll do an underbonnet picture at some time.

System still seems to work but I would like to get things correct If I am to fit an alternater (my first choice is a french delco one that came off a scrapped simca - that will be fun getting a reasonably sized drive belt for it ) to the up-coming 1098 Traveller.
