johnny_h Posted February 9, 2008 Report Posted February 9, 2008 So I'm trying to get my head round the wiring for the lights so I get out out the haynes manual but the first thing I notice is the indicators have only 1 wire with a bullet connector coming out of them yet the haynes manual shows 2 wires coming out and a ground! I'm guessing the ground is the actual indicator body screwed to the car body but why does it say there is one black/white wire and one brown wire?
MK1 Dave Posted February 9, 2008 Report Posted February 9, 2008 Do you have the six-clock dash? The six-clock type indicator on the dash does have two wires and just slots into the dash facia. The dual clocks might be different. You're right about the casing being a grounding plane the sixer's speedo light are the same deal. Dave
johnny_h Posted February 9, 2008 Author Report Posted February 9, 2008 I have a 6 dial dash but I'm talking about the indicators on the front of the car. They only have one wire coming out but the Haynes manual wiring diagram shows two.
MK1 Dave Posted February 9, 2008 Report Posted February 9, 2008 Ah I do apologise. Maybe Haynes were thinking ahead and decided that most of the bodywork would be filler anyway so its best to run out the return wire! Dave
flyingbanana Posted February 9, 2008 Report Posted February 9, 2008 mine only has the one lead, the main live wire and then its grounded from the body.....and it works no problems .....i assume if the book saying it has two wires they would be for the works indicators
johnny_h Posted February 9, 2008 Author Report Posted February 9, 2008 that makes sense. But having said that the diagram shows only one bulb in the unit. The indicator does actually work fine with one wire attached but the headlamps are not working so I thought I would check the wiring diagram and this is the first thing I noticed. The extra (brown) wire from the indicator is also connected to the sidelight bulb of the headlamp in the diagram.
flyingbanana Posted February 9, 2008 Report Posted February 9, 2008 on the headlight their is 4 wires.... side light (live ) , main beam ( live), full beam (live) 4th wire (brown ,earth) then the brown extends to the earth of the side light , then their should be a separate wire just for the indicators ...well thats how it is on mine ...
johnny_h Posted February 9, 2008 Author Report Posted February 9, 2008 Will one side work without the other or do both sides need to be wired up?
flyingbanana Posted February 9, 2008 Report Posted February 9, 2008 Will one side work without the other or do both sides need to be wired up? good question......i think they should work has long has you have power going to them.......what problems are you having with them johnny?....do you have a volt meter ?
johnny_h Posted February 9, 2008 Author Report Posted February 9, 2008 no volt meter lol. i only can get the main beam working on one light, can get sidelights on both fronts but one rear light is out. the main beam indicator is always alight on the dash. when i pull the dip switch all the lights go out. hows that for starters.
PAUL MANN Posted February 9, 2008 Report Posted February 9, 2008 you could have a duff bulb & its sending either a bad earth or a live back down the loom,also check the fuse holder clean contacts & the fuse contacts,could be a dirty connectionmgood luck my friend
flyingbanana Posted February 9, 2008 Report Posted February 9, 2008 do you still have sealed beam units? if you have,the full beam may of gone on the one of them and why its not working if u do have sealed beam units swap the lights over and see if it still works, next best option if you dont have a volt meter if the full beam light is staying on and you lose the whole lights when dipped ...its suggests to me that its not wired correctly the only way to find the problem out is by getting a volt meter......you can pick up cheap ones for about £5....plus its handy for when you need them for when you have problems like this and you can also check to see if the bulbs have gone or you are getting continuity between the connections or breaks in between also if you are getting the correct voltage or see if the wire is live or neg....has paul says its worth checking the the connection for dirtiness has well sorry i cant really help sort your problem out over the pc, just give hints what it might be good luck with it
johnny_h Posted February 10, 2008 Author Report Posted February 10, 2008 Cheers I think I'll grab a meter and have a proper look at it.
Rick Posted February 10, 2008 Report Posted February 10, 2008 i dont think mine worked til i fitted all the bulbs, including the rears. the fronts are one wire to the back and one wire connected to the front panel as an earth. i have vacuum formed plastic indicators though cant remember what the originals were like
johnny_h Posted February 11, 2008 Author Report Posted February 11, 2008 Ok I sussed the rear sidelight after untaping half the loom. One of the fuses wasn't sitting right So I retaped the loom and all the sidelights were ok. I then looked at the fuse box a bit closely and found that if I moved one of the multi-connectors to a different pin the main beam lamp on the dash went out so I got out the haynes manual to check where the plugs were sposed to go and that didn't help coz... My connectors have 5 pins and the haynes manual has 4 pin connectors anyone got pics of how it should be?
flyingbanana Posted February 11, 2008 Report Posted February 11, 2008 start from the top with the 2 pin one then the next one connects directly underneath ...the very bottom one has nothing on it
johnny_h Posted February 11, 2008 Author Report Posted February 11, 2008 is yours a 5 pin connector? If I do it that way there will be two at the bottom not one. Could be the headlamp dip relay?
flyingbanana Posted February 11, 2008 Report Posted February 11, 2008 it must be 5 pin , can only check next time im at the car
johnny_h Posted February 12, 2008 Author Report Posted February 12, 2008 Think this is half the problem...
flyingbanana Posted February 12, 2008 Report Posted February 12, 2008 right i had a look at my fuse box....cant tell which way your top connection is facing...but the little extended bit is at the top, next one the extended tab is at the bottom , next one has nothing connected to it...last one has a single wire to it
