[Healeys] Replacement Turn Signal Relay.

[Michael Salter]

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.
