Hazard wiring prob

[dogwood]

The relay is ok, tried swapping them round
(Ie flasher to hazard)
They are standard Ford flasher relays.
With it wired the way it is, and fitting the idiot between the
relay and switch, the relay gives power to the idiot light.
So it flashes like mad all the time.

BTW glad it ain't just me....

Surely it could only do that if you had wired the other side of the idiot light to +12 instead of ground?? Otherwise where would there be a feed to make the relay go doolally? EG the light is powering the relay rather than vice versa.

Another thing I have spotted but assume is an omission, you have not shown a switch linked to the double pole switch that actually switches the feed to the hazard relay. If it ain't there it needs to be otherwise the relay will always be trying to flash.

Nope not an ommission.
That's how I though it should be wired.
It will only flash when power is drawn from the relay
IE indicator is switched or hazard is switched
Turning on the bulbs.
Otherwise I would need 2 switches.

The relay is powering the idiot light
IE 12v in to relay then common out to the idiot light before the switch

So let me see if I have this right then, When you switch the hazard switch on and the idiot light is removed all 4 indicators flash. If you turn off the hazards and turn on the ignition the indicators work ok - correct so far?
If so your last statement can't be correct - all the double pole switch is doing in effect is connecting the left and right indicators to a pulsing 12 volts coming from the hazard switch. That would have to mean there is 12 volts being switched by the relay and coming out of the "c" terminal. Put a DVM there if you have one and you should see that.

Ah, ok, think we might be getting somewhere now. Just a min, need to think.....

[dogwood]

OK.
Everything works just as it should.
There are 2 relays. one for the indicators and one for the hazards.
Not the normal one off, like Ford does it.

The only prob I got is the hazard idiot light.
Just cant figure how to connect it without it either
coming on with the indicators, or getting power from the haz relay

Ok, I guess what is happening then is that when you move the idiot light to the other side of the switch the small amount of current being pulled upsets the hazard flasher - I guess it flashes really fast like it would if you had one bulb blown only maybe quicker? Only way I can think of around that is with a 3 pole switch, the third pole switching the idiot light. The way you have done it is a bit weird as normally it is done with just a single flasher unit and a complex switch, as far as I am aware. Brain's a bit tired tonight so I might be wrong on that.
