Wow, after more than 30 years, new information bubbles to the surface.

For decades, there were two different fuseboxes known for the Series 3 Spiders; the early bullet fuse type and the later, blade type. Well, a 3rd type has just been discovered. This 'interim version' fusebox, an example of which resides in @JCMelvin 's 1986 Spider, has the bullet fuses of an early box combined with the relay/flasher locations of the later box. Preliminary research indicates that this box was first fitted to production Spiders in March 1986 and, I will assume until further research can be conducted, was used until the blade style fusebox came along in 1987.

Time to blow the dust off of the 5 different 1986 Spider parts microfiche and have a peek.

Poo. It's always something. Need to fix the fiche reader first.

Interesting. I always assumed that the switch to blade type fuses happened with the late '85 to '86 models. Never knew about such an interim fuse box.

UPDATE....
I received the new flasher unit today, plugged it in and the turn signals work! Many thanks to PAPAJAM for his time, advice, and wiring diagrams. Even though the diagram for the car had the flasher in the wrong location I was able to use the wire colors to find the right one, then do some tests and confirm power and complete connections through the switch and out to the lights and nail it down to a bad flasher unit. We also all learned a little about late 85 fuse boxes. Mine has relay locations of an 87 but bullet fuses, which are not dependable and I hate. So the next thing on the list is upgrade to a new box with blade fuses. Again, thank you to the AlfaBB and all who helped!

That's great news!! Thanks for the update!

I wrote earlier that Alfa used three different fuseboxes for S3 Spiders. Well, I was close but did indeed miss the target. After fixing the microfiche reader, I set about researching this 'third' fusebox thing.
After studying a dozen or so fiche (I lost track actually), here's what I found.

There is an early fusebox with bullet fuses that uses an early wiring harness.
There is a late fusebox with blade fuses that uses a late wiring harness.
And then there is a third combination that uses an early fusebox with an interim wiring harness. This interim harness changes the location in the fusebox of the rear fog light and rear defogger relays as well as the flasher. This is the harness that @JCMelvin has. And because none of the technical documents I used as the basis for the color wiring diagrams showed this variant, it never got drawn. Until now. I'll draw and add this variant to the 1986 diagrams.

Credit to JCMelvin for discovering this omission in the factory documents!

Very cool thread. When I first dug into my fuses with the help of the Bentley manual, I noticed that things were messed up, and it seemed like a combination of both. Glad to see that I wasn't slow in the head, and actually saw what I was seeing! Also, the spare fuse holders is in a different location than the two listed in the Bentley.
