Series 3 Flasher unit

Nov 04, 2005 7 Replies

Hi, Looking at the Haynes wiring diagram for my 1981 series 3 the flasher unit should only have 2 wires connected to it. But looking at the flasher unit installed it has 4 wires attached to it.



The new 2 pin flasher unit I bought won't work with the Dark green and light green wires as stated in the manual.



Anyone any ideas of what the other 2 wires do 1 black and 1 brown......



Cheers Adrian Ford


could do with the numbers off the old flasher relay i.e. the terminal numbering Rich

Adrian Ford came up with the following;:

I took my old flasher unit to Halfords, found something identical ... with full instructions included on the packet ... ;)

ISTR that the four wire relay was for extra lighting, such as for the towbar electrics or a rear worklamp etc.

could be for trailer electrics, but i doubt you'd wire a worklamp to a flasher unit, except if you wanted a strobe-light work lamp! coud make for some interesting camps.

LOL, I was also thinking of something else at the time I wrote it ... Multi-tasking not my forte, it seems. ;)

Cheers all Will take back the 2 pin flasher and exchange it for a 4 pin..

At least it proves you're not female. ;-)

vehicle wiring products have a good selection of flasher units if you wanted to look at them and try to find one that matches your old one.
