Headlights dont work :(

[grinder]

Hiya chaps

breaking away from the other thread of the "car wont work" as its getting a bit confusing in there

so starting a nice clean thread ( for now - who knows where it will end up !! )

so anyways ...

i cant get the lights to work on the cab

the wont come on and they wont pop up using the switch

i have tried 4 switches with no luck

this is where i am now : ( see pic )

1 - put 12v to this and the lights come on
2 - put 12v to this and the lights come on
3 - put 12v to this and the lights come on
4 - put 12v to this and the lights come on
5 - put 12v to this and i get a BUZZZZZZZZZZZZZZZZ noise

and none of these make the lights pop up

HELPPPPPPPPPPPPPPPP

If you look very carefully the pins on the relay are marked:
 
1 NO - Normally Open
4 NC - Normally Closed
2 COM - Common Power
3 COIL - Coil
5 COIL - Coil
 
I assume you mean that you are putting 12V on the socket side of this relay and that this is the headlight relay?
 
If you put 12V across 3 and 5 of the relay you should get the relay to click.
 
If you put 12V on 3 or 5 in the socket it should have no effect.
 
Pin 2 in the socket should normally be at 12V. Connecting this pin to pins 1 and then 4 should make the lights go on and then off on high or low beam according to the stalk control. In the socket only one of pins 1 and 4 will be connected. That connection runs to the dashboard
 
The headlight relay doesn\'t make the lights pop-up.
 
I\'ve run out of time to help, there is an FC wiring diagram on RX7club.com, it is similar to this from the FD
 

[Prof]

Here\'s a diagram from the US pdf\'s - I am guessing Jap spec is similar and does not havee \'dip dim\' circuit.

The relay you have should be for selecting low beam / hi beam as far as I can tell.

hiya chaps

well thats very confusing !! LOL

so what it looks like then is that i have the relay for dim and dip - so OK thats not a problem !

all i need to do now is work out which one does the actual head light motors !!

there is a round connector near the back of the lights - i think this does the motors - just need to sus out which pin sends power to them !!

i must admit im hopeless with electronics and cant read a wiring diagram for the life of me ! LOL

im wonder if i can just cheat - and send 12v down the retractor line and see what happens ??

Stu

[Prof]

You should be able to - that\'s pretty much what the retractor overide switch does.

[grinder]

had another 4 mins on the car !! LOL

just got the bonnet up and the better half came back

undid the round connector at the back of the headlight ( behind the battery )

there are 4 pins in there - applied power to each one and NOTHING

this is really proving interesting

any one know how to get the motors out ??

Stu

[Mobilemick]

I take it your playing with the Probe Stu

when u touched the probe on the connector,  did it turn green,

[Grizzly]

Have you got a diffrent Power Probe to me? Mine shows red for Power and green for Neg?

Stu, Don\'t rule out the Pop up motors arn\'t Stuck or Corroded, when i bought my car mine where open slightly and it had me running round for Three days scratching my head, I found with mine when the Motors stick The lights can still be put up and down (with the Aux Lights up switch) if its the Motors this don\'t work.

Also Don\'t trust the main Light switch, if its been stood a while my Lights used to stop working, if i played with the Switch it would sudernly start up again.

[Mobilemick]

Yes, they all do,  what i mean is, if he touches a pin without pressing the button,  does it go green,

Mick

[grinder]

errrr to be honest - not sure if it went green or not

should it go green - or is this bad ??

even with the lights wound up - they still dont come on or off ??

i dont know if its really bad wiring from the switch or what

Stu

[Mobilemick]

If it goes green, you know the headlight is connected to the relay,  if there is nothing there, the headlight will be unplugged,  even if the light is knackd, u will still get green light

[Mobilemick]

Feed the wires from the switch, if the lights work  then u know switch is faulty,
If it doesnt light anything,, then feed the relay, if that doesnt work,  check the connections on the light(headlamp)

th

[grinder]

thanks guys

i will check what colour light i get on the relay and i will try and feed it from the switch end and see what happens

we know that feeding the relay works - as i can get the lights to come on from there

if i get 20 mins today i will try it

i will report back with finding and pics if possible

Stu

[Prof]

Stu,
 
do the lights come on from the light switch - or is that only when you put 12v on that relay ?
 
If that\'s the case, locate the other relay that feeds the one you\'ve been playing with - it will have only 4 wires connected.  This connection from the COM relay on the one in the picture connects to the NO connection on the relay with 4 wires. This is the headlight relay - not the dip/dim.  On the COM terminal of this relay - try jumpering 12V feed straight from the 30A lights fuse to that terminal - that may then operate the lights at least from the switch.

[grinder]

dave ,

i can only get them to work by jumpering the relay

i tried to test another relay at the side of this one - and that puts the lights on aswell

what i need to do is work out whats dim/dip and what the other one is

i might wind them up by hand and see what lights with what relay ( as i cant really tell when they are down - you just get light )

the only thing im thinking aswell is ... is the jap spec light switch different to the UK one

i cant even test what mine does when you apply power as mine is a UK spec - although it could be worth a try
