[Healeys] Replacement of Turn Signal Relay.

[josef-eckert at t-online.de]

Michael,
Since it's almost the same topic, but what bothers me much more is 
replacing the relays on the 6-cylinder Austin-Healeys.
The top screw that holds the relay is inaccessible with a screwdriver when 
the cold air duct is installed. The same goes for
the upper cable clamps. Is there a trick to removing the faulty turn signal 
relay and installing a replacement without removing
the cold air duct and potentially damaging or crumpling it?
Thank you for any helpful suggestions.

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!!

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.
