Replacing old flasher relay with New...

[Walt]

I'm replacing my old flasher relay (which died) with a new modern one, then as the connection layout is different I'm going to try with some short jumper wires back to the fuse box.

My only question is that the old relay (4 connections) had a "KBL" labelled connection, which my new modern one (3 connections) does not.

So if "KBL" does not exist on the New relay how do I replicate how it worked before? Bentley shows the connection leading to the instrument panel.

Any ideas? Or does KBL not really matter?

I've got a 1971 microbus and the 49 and KBL are just joined together so that may be the answer. Have a look on samba.com under technical/wiring.

Do the new ones "beep" ? (or should the old ones beep!) - maybe I'm a poor driver but I sometimes find myself driving along with indicators unintentionally left on - and with the old drum brakes can lead to interesting situations...!

Kbl is a switching earth for the tell tale light on the dash.I think you will need a 4 pin relay for it to work.I'm not sure if you can earth the tell tales and use the indicator outputs to power them,you would have to isolate the other dash lights.It might be easier to get a relay off Samba.I have seen 4 pin ones at Heritage.

Thats interesting, my bus has some random relay, it all works, though the tell tale doesn't, have to fit a buzzer for the MOT, can't remember if it ever did, think a wiring list off the samba is due...

my old indicator relay would only power the tell tale lights if I linked the 49a and KBL. I thought it was because it was faulty. However it worked fine like that. I replaced it with first a three pin relay which caused the indicators to flash too quickly and then a four pin relay which is correct for the year (1970).
The weird thing is that this relay would not make the tell tale lights work until I did the same as the old relay and piggy-back the KBL onto the 49a terminal! No idea why this happened but it works fine.

To make the ticking sound of the relay louder, because I sometimes forget the indicators are on :roll: , I have cabled tied it to the cool air vent and that acts as an amplifier and everyone in the bus knows they are on including the driver :lol:
