[Healeys] Replacement Turn Signal Relay.

[simon.lachlan at alexarevel.plus.com]

Regarding these contraptions, there is a third way. I've mentioned it to M before....one can gut the old relay and rebuild its internals with new, modern, relays. I've done two or three. The first because my original had gone into terminal decay and the others because I'd bought clapped out originals at a boot fair. Anyhow, the first one's been in the car for some years now and works fine. The others are in one of the "boxes of useful things I may need one day". I've done the same to overdrive relays. By the way, I don't claim to be the first person to have done this!!

Subject: [Healeys] Replacement Turn Signal Relay.

All Big Healeys prior to the later Phase 2 BJ8 use a Lusas 33117 relay for the turn signals. This relay connects the appropriate lamps to the turn signal flasher unit, overriding the brake light switch on turns.
These Lucas relays were a very primitive (by today's standards) but very robust unit and could withstand a short circuit as often happens with the glass lens type 594 turn/side/brake lamps used on these models at least until the fuse blew.
Within these lamps it is very easy to produce a short to ground.
Over the last few years replacements for these relays have been provided, under the Lucas name and the same 33117 part number, which have been completely redesigned and incorporate 2 modern G2R-1-E relays.
I have purchased 2 of these modern style relays and both have failed because the  G2R-1-E relay relays don't seem to be anywhere near as robust as the originals and fail before the 35 amp fuse can protect them..
So, a word of caution, if you are using one of these (improved) cheapo repo turn signal relays, be very careful to avoid short circuits in the turn/brake/side lamps.
The attached pics are of the original type and the circuit board from the "improved" replacement.
