Will let you know when I sort it.
What would happen if the input and output of a flasher relay were swapped around?
I think this may be why my indicators and hazards don't flash (they just stay on).
If I swapped the terminals around, could anything bad happen? Just want to check before I do anything silly.
Thanks
James
ETA: I am using LED indicators all round on my car. Using a standard flasher relay, the indicators are more dull.

If they stay on i would first check your earths.
firstly what relay do you have?
two pin will not work with hazzards i.e. it operates 2 lamps on one side not all 4.
2 pin has L and B termianls,
B = 12 V
L = to indicator switch
am thinking about this but cannot see why it won't work either way - the flashng is achoieved by a bimetallic strip that depend on current flow
not current or voltage direction.
if you have electronic relay, pins labelled 49, 49a, 31, then it is a different question altogether.
see here for connection

to figure out what is wrong, I would remove realy from car, wire up 12 V to 1 pin and 2 indicator bulbs in parallel to other, other end of bulb to
ground nad it should flash.
are you using LED bulbs perchance?

I have a three pin relay, i.e. 49, 31, 49a. (30W - supposedly for LED lights)
Using a normal 3 pin relay i.e. (110W) the indicator/hazard lights go slightly more dim, if this helps at all.
I have LED indicators all round i.e. 3 pairs.
ok, now we have mnore info.
answe to your quesiton, no you cannot just swap wires willy nilly and which were you proposeing to swap as you have a choice of 3?
as per linky,
49 goes to 12 V
31 goes to 0 V
49a to indicator switch.
the lamps will be connected to other end of indicator swtich with one terminal of bulb to 0 V.
as you have LED bulbs illuminating, it would appear you have wired them corret way - they are direcitonal.
Do they have to flash for IVA?

I would have thought so, but I got my car through the SVA test before the cutoff date. Pending this small hiccup with the indicators, I will be putting it in for a retest soon..

The indicators must flash at a rate of between 60 and 120 times a minute (with all mandatory indicators working, and with the engine running)

I have no plausible explanation for that; it may be that the contact resistance is greater for the stanadrd relay but I cannot imagine it is so much more as to make the lamps dimmer.
I have heard that some people use resistors to up the load on the relay to make them flash properly.
If you have an electronic relay, then it should not be dependent on the load i.e. how many and what sort of bulbs you have fitted.
To test that theory, replace frotn and rear LED lamps with bulbs - pull them out of your tin top of buy pair from halfords - a couple of quid - and handy to have spare.

Thanks for your help there, definitely some stuff to get stuck into Will let you know when I sort it.
