<div>Yes, and time for a reminder to fuse the tail lights <strong>red wire</strong> as if in a rear end collision the shorting of the lamps could burn all the way down to the panel. At the same time the headlights, which are also unfused, could use an inline unit at the<strong> blue wire</strong> of the headlight switch. Not much fusing on the Healeys which makes for good Lucas smoke.

<div>
<div>
<div class="gmail_default" style="font-family: arial,sans-serif; font-size: small;">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.</div>
<div class="gmail_default" style="font-family: arial,sans-serif; font-size: small;">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.</div>
<div class="gmail_default" style="font-family: arial,sans-serif; font-size: small;">Within these lamps it is very easy to produce a short to ground.</div>
<div class="gmail_default" style="font-family: arial,sans-serif; font-size: small;">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. </div>
<div class="gmail_default" style="font-family: arial,sans-serif; font-size: small;">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.. </div>
<div class="gmail_default" style="font-family: arial,sans-serif; font-size: small;">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.</div>
