Flashing headlights

[steveg]

Good evening all , I have a 2004 westfield and replacing all switches . Current have a blue switch for headlights 2 positions that puts sidelight and main beam on. I then have a toggle switch that puts on full beam however  I can't flash the headlights when headlights are off with this toggle switch so not sure if they should . How do I get them to flash without headlights on ? Appreciate help before I buy new switches

Does the toggle switch only have 2 positions? If so you could instal a separate flash only switch

Hi , the toggle only works when I put blue rocker  switch on to main headlights . The toggle switch has position to on and then back to off. My thought was to repalce the blue rocker to a green headlight rocker switch and then add a blue rocker switch for full beam and then repalce the toggle switch  with a sprung type for flasher however I don't why it don't flash when lights off .

I've done a bit of web browsing, I have no Westfield experience, so take what you will from the following.

Have a look at the wiring diagram at http://westfield-world.com/wiring_diagram.html   This is most likely what you have. You can see that the headlight relay is only energised from a switch that has 3 positions, off, side and headlights (probably blue rocker?) When the relay is energised it can have it's output controlled between High/Low beam by a second two position switch (what you call toggle I assume). There is no provision in the circuit to energise the Main beam independently, as you desire. To do this, as steveg suggests, you would need another switch and relay. This switch would need to be spring back to off when flicked on.

I don't believe it needs another relay as it is currently being controlled by a changeover relay (labelled light solenoid), if the wiring is as @Sparepart suggests than all you need to do is provide a +12V feed through a momentary make/break switch (push button/flick) whatever your preference to pin 36 on the light solenoid. 

Scrap that, Apologies, that would only work if the light switch was already on dip

Wrong answer

IF your Westfield is wired as per the referenced diagram then what happens right now at the relay is as follows:- Power arrives at pin 30 from the 3 posn switch when it is headlights on posn.  It comes up the wire colored yellow in the diagram (which also energises the fog light switch). If there is no power on pin 86 (looks like 36 on diag) then the relay is switched to energize pin 87 (blue) which powers the low beam filament. The high/low beam switch is used to energise pin 86 which causes the relay to switch power to pin 87A, from 87, i.e. the low beam filament has no power and the high beam filament is given power, and also the high/low beam indicator lamp is illuminated. In order to implement a high beam "flash" function then another relay is not strictly necessary. A momentary switch could be added that enegises pin 87 directly from the live thats live when the ignition is on, so the lights could flash at any time the car has the ignition on, the best place would be from fuse that powers the first connection no 6 in the row of black terminals in the diagram that is for the lights. There is a potential problem with this however, and that is if the headlights are on and using low beam. In this case the "flash" switch would illuminate high beam at the same time, both filaments might draw too much current through fuse 6 and it might blow. So to rule this out, the "flash" switch could be used with another relay that stops power being given to 87A  via the flash switch when 87 is energised (i.e. when low beam is on). Hope this makes a bit of sense.
