[xj] XJC turn signal loss

I have a 1975 XJC6 cylinder with turn signals that are
now at nonfunctional. The fuse is not blown. I believe
the next step is to check the turn signal relay. Could
anyone direct me to the location of this really ?

I seem to remember it was under the dash, tucked
inconveniently behind the fuse rail. Should be the same as
any Series 2 though, C or not.–

Relay or flasher unit, the device with the bimetallic strip that op
that opens and closes the circuit to ‘‘flash’’
the lights?

Try the hazard switch. if the lights flash on and off that fla
flasher is OK and the issue is elsewhere.

If still no go,
exercise the flasher switch,
in other critters, that often restores the circuit

Hi Carl, Before I left for work this morning I checked the
hazard flashers…only the left front and rear
illuminated,nothing on the right. When I get home I will
pull right side, probably all, lenses and check bulbs and
sockets. Brake lights and tail/headlight are all operable.
Flashers and turn signals are probably a different bulb.
Thank you both for your replies.

The wire thing. With a meter,
probe the dark socket for volts.
A test light will do it as well.

I suspect you will find none!!

Find the ground and clean it.
I’d put my money there, if
I was a betting man, I am not.

and, just for fun, in the socket
or on the bulb, the little
lead contact may be so worn
as to not mate up. A fresh
new bulb often fixes that.

Good morning, Before I go any further I should mention that
the steering column hazard switch has some slop in as you
move it up and down; it also moves side to side. Could that
be the source of turn signals not working and hazard
flashers only working on left side front and rear?

Well, odd things can happen
in the electrics. but,
I don’t think the slop
could cause dark lamps on
only part of the circuit.

All or nothing, more likely.

Go to the dark sockets and
probe for volts there.
My bet is a poor local ground.

Happy Easter.Well turn signals functioning fine after
flasher replacement. I spent the good part of yesterday
replacing the hazard switch. Of course SNG sent me a switch
for a right hand drive but the good news there was enough
wire length to simply rotate the switch and fit my left hand
drive column. The hazards work perfectly now but the bad
news…when I turn on my left blinker the green indicator
illuminates on the dash as expected but now so does the dash
hazard indicator.So be it. I’m not taking that apart again
until I need a turn signal or wiper switch replaced.Thank
you all for your input…now on to the headliner.

Hi
I have the exact same problem
When I indicate left my hazard warning light flashes
Did you ever find the cause?

Must be your hazard switch.

**
Welcome on board, Ick - but what happens to the indicator lights outside…?

…and to the direction warning lamps on the speedo/tacho? And does the Hazard operates normally when the switch is used?

The problem may well be in the Hazard switch as Aristides says. But the direction indicator/hazard set-up is rather complicated - also involving diodes…

Hi Frank
Thank you for your response
The indicators outside work as they should and the taco and speedo lamps work as they should
It’s just with the addition of the hazard warning light blinking when I turn left
This first started a couple of years ago after having the ignition barrel changed
It was assumed to be the flasher relay but I’ve just changed that so I’m a little stumped

njk1963,

I have fixed a few directional signal problems in my Series III XJ6s that had me stumped by removing and replacing their Hazard Switches. The Hazard Switch is complicated, fragile, and doesn’t like being jostled like it might have been when someone worked on your ignition barrel.

I suspect that a new Hazard Switch will fix your problem like it did mine.

Paul

Thanks paul
I do have a spare switch I can swop out so I can give it a go
I’ll let you know if it works

**
In short, Ick - the only problem is the hazard warning lamp coming ‘on’ in ‘left’ indication…?

Nominally, the hazard warning lamp is powered via the hazard warning switch, but only with the ‘hazard’ switched ‘on’.

While a hazard switch fault is a possibility, as Paul suggests; a misconnection at the hazard switch is also possible. If the lamp wire, light green/green, is connected to the ‘left’ indicator, either at the stalk switch or at the hazard switch; it will give the symptoms you describe…

The lamp wire should be the only wire at its connection - #9 at the hazard switch. If the lamp wire is ‘crossed’ there will be another wire where it is connected…

It warrants checking - but in any case; if you change the hazard switch, make sure the connections are correct…:slight_smile:

As an aside; changing the ignition switch can have no direct bearing on the fault itself. However; changing the ignition switch may have restored correct power to the indicators - causing the fault to show up…:slight_smile:

I’ve checked the wiring to the Hazard switch and it is as follows
#1-Light green/blue wire

#2- Light green/white wire

#3- Light green/red wire

#4- Light green/green wire

#5- None

#6- Light green/pink wire

#7- green wire

#8- Brown/orange wire
I’ve seen mentioned before on other forums about the number 9 terminal but mine is from 1-8 with the 5 terminal blanked off

Great news
Swapping out the hazard switch cured the problem
Thanks for everyone’s help
