Again all great input and thanks for taking the time GTD!

I believe I implemented all of the changes correctly - it took a fair amount of time on the gauge so I hope I got that correct.

I changed the title and added 6 fuse to the name - I already have 8 fuse 750 and 101 diagrams though I will need to update those with the changes we implemented here.

Some of my assumptions which may be wrong on 6 fuse cars
Berlina and Sprint Normale cars used manual engagement for the starter motor
Veloce cars had starter with solenoid
Sprint Normale dash switch order went from L to R - wiper, dash lights, interior lamp
Sprint Veloce dash switch order went from L to R - interior lamp, dash lights, wiper
Sprint Veloce had horn relay and two horns, negative ground and fuel pump, Magneti electrics

I am almost done with the Veloce versions and i will post those soon.

Doug

Your latest diagram looks GREAT.

One more point .. all Alfas with Nord engines use clockwise distributor rotation with a 1-3-4-2 firing order.
#1 cylinder wire position on the distributor cap is typically at 2 or 3 o'clock.

Also - just nit-picking here .. if you Zoom in on the LUCAS thermal cut-out (#38) .. the detailed printing is inverted !

Regarding 750D Spider diagram, while I understand that the factory diagrams you are referencing include it ... on a USA market Spider with "football" LUCAS 523 tail lights there were no reversing lamps included in the tail light assemblies.

All fixed GTD - and may thanks.

Here are the corrected versions and the E and F versions as well.

I have been updating my 750 8 fuse and 101 diagrams per the changes covered here. I will post those separately.


I removed all of the earlier files to eliminate any confusion and put the latest diagrams in the first post.

Hi Doug:

Just a small note to thank you for your work! I was referred here by Papajam and I am delighted to find the diagram I need to check my Sprint normale's wiring harness. Invaluable help!

Thanks!

Are you still working on the 6 fuse diagrams?
Couple of thoughts (looking at 750E):
I would assume that all 6-fuse setups were tunnel case gearboxes ....... never seen a tunnel case with backup lamp switch.
You show a steering column headlight high/low switch, so the diagram should be marked "not USA", which had the LUCAS floor switch.
I don't see a "door button switch" for the ceiling lamps ......... which is my reason I was interest in the diagram .......... what is left of my 750E harness indicates that the positive (+) wire went to and from the door button instead of a "ground" wire like on all 101 cars. Still trying to find somebody else with the same to verify.

Carl,

The early column shift tunnel case cars had backup lights, the switch was mounted forward of the gear changing mechanism attached to the steering gear column in the engine compartment.
