The emergency Flasher Relay on my '66 Super burned out. The stubby cylinder one that's mounted on the fire wall behind the booster. All I see at Classic or OKP are the longer relays. Or are these just the signal relays? Will these work? Going to dig through my parts arsenal as I think I have one of the long one with 3 connectors. Thanks Mark in LA.

Have you tried it in your Spider? You have and old one I think. If it works there it will likely work in the Super. The original has three prongs (and leads Rosso, Verde and Nero). Don't need another non useable part on the shelf. Let me know. Mark
I have one in my 87 which takes the 4 point. Did not know yours was the three point. Try Rockauto. I believe I saw some 3 terminal relays for hazards there.

Ossodiseppia understands this stuff better than I do, but...

I don't think it's as simple as "any 4-terminal flasher will interchange with any other 4-terminal flasher". My sense is that the BOSCH 0236850-002 part that handles the emergency flasher function on the early 105's is unique; I'm skeptical that you can simply substitute a modern, generic, electronic flasher module.

I'm assuming that functions performed by the BOSCH 0236850-002 are handled by two or three of the devices in the schematic that ossodiseppia posted in #2 above.

The hunt is starting to get interesting. Classic says the new longer style should work and send it back if it does not. (Love those guys as i bought it in '15). Alfastop told me they are hearing of the new style being faulty out of the box, hmmmm. Seen some mid 60s VW Bosch applications on the internet that I might try, part numbers not close. Waiting for response from OKP. Moss has some mid 60's MG units that look similar but not Bosch, fearing prince of darkness Lucas. Here we go.....

Agree, really don't want to go into the wiring so we are continuing the hunt. Some mid 60s VW units look spot on, but they're pricey. Note from European vendor says he has heard that many of the new replacement units are faulty.

Hi all,

@ ossodiseppia, could it maybe be Bosch 0336850002 instead of your number ?

If so, please see my pictures of a page in an old Bosch Catalog.
If I reed this correctly, that 0336850002 would have been superseded by the 0336850010.
This superseding would contain following changements:
12V 20W became 12V 50W
Length of the round aluminium housing went from 29 mm to 47mm

Please know that I'm not a specialist in this matter but I would guess that the Bosch 0336850010 could be used here.

On the German Ebay site, I found one seller that has the new Bosch 0336850010 in stock. I'm not connected with that seller and I don't know whether his parts are original or reproductions but they seem to be original on his pictures. It would be wise probably to ask him about originality ...
see Ebay nr: 372720421984
Maybe this can be of some help.

Seems like at some point in the past. There was a thread on converting the black Bosch flasher box to a modern 3 or 4 prong one. It was either in the Spider or the GTV forum.

Use to have a those organized but the new and improved BB did away with that function and I'm not going through 100 plus pages of threads.
