Ke55 Headlight Problems

[jara]

So when I try putting my headlights on, nothing happens except the high beams indicator comes on. I push the stick forward, the beams indicator turns off and still no lights. But if I pull the stick towards me, i get lights (not sure whether high or low beams though, cause they're pretty much the same).

 

I replaced the headlight stalk today, which took bloody ages to get in. Didnt help though, same problem, different stalk.

 

any thoughts? i really don't wanna have my wallet raped

 

 

cheers

This is KE70 stuff, but I expect it to be the same.

 

The drawing shows how the lights work, an abysmal system where the relay puts power to both filaments of the bulbs at once, then selectively earths one filament or the other.

 

You can see why you can have full beam by pulling the dipswitch back, it earths the relay & puts power to the bulbs, then also earths the high beam and the low beam together. So flashing your headlights should be both filaments at once.

When you let it go and it moves to dip, it earths the low beam.

When you push it forward again it earths the high beam only on the other earth point.

 

The wiring diagram is where it goes in the car. The red/black is the main power wire taking power from the fusible link (8) to the relay, and then through the light fuses and off to each bulb, where it joins both bulb filaments at once. The relay is switched on by the dipswitch stalk being turned and earthing out the R/W wire.

 

Now both filaments have power, you need to earth one of them to get light, and that's what the red/yellow or red/green wires do. The dipswitch is set up so it earths either dip or full unless you grab 'flash.

 

The red/black power is obviously OK on your car, and the red/green dip. Seems like you have lost the whole R/Y line through a bad connection somewhere, assuming hte new stalk is working OK All you can do is trace those colours and see where the power ends.

 

I had the same recently, but in my case a relay had died. I've wired mine around the other way so power goes to two relays and they work the lights, & they're MUCH brighter!

i hope you upgraded the wiring to the lights as well while you were at it (so the lights can get the full current to them instead of the half current through the original wiring)

Yes, the original wiring just turns the relays on and off, so they're only passing a low current and that doesn't affect the headlights at all. The actual wiring to the bulbs was all new and larger wiring. Its in here, although I see the link to 'how to do it' is broken.-

I followed the wires as best i could and found nothing, There are a few old connections in the engine bay though. I don't know what it is called, but the connector under the steering shaft, that connects 30 or so wires. I undid this, blew in it and plugged it back in, and problem solved. how easy was that hey? I also noticed that a wire in there had melted some of the plastic around it....

 

this car is absolutely chock full of wires, so many things have been done / undone. I dream of the day when it's all cleared out.

 

cheers guys. also, is it simple enough for me to do that double relay thing myself? I don't even know where to find the first one
