paulbrem Posted April 22, 2020 Share Posted April 22, 2020 Hey Yall ? Not been active for quite some time but....... Recently been working on my almost a decade long project, nearly there, and the front indicators have no power to them. Harzards are fine both side and rear flash correctly, all bulbs working Indicator stalk side and rear flash quickly indicating bulb out, no power to front at all. I have replaced the front bumper, I have installed new larger side mount intercoolers. After spending time on the car on and off, basically I don't have a clue if I've missed anything. The ground is OK as its shared with the side lights and both sides light up fine. Has anybody any ideas please?? I'm hoping to get it in for MOT early next month ?

paulbrem Posted April 22, 2020 Author Share Posted April 22, 2020 Just to add all other lights are working fine and the 2 fuses near the fast pedal are fine. Quote Link to comment Share on other sites More sharing options...
Bones28 Posted April 22, 2020 Share Posted April 22, 2020 Maybe you pinched the positive wire somewhere under there. Quote 2002 Porsche C2 996 3.6 1991 Nissan 300zx TT Project 1995 Nissan 300zx TT Crashed 🥲 1997 Jaguar XK8 Scraped ☹️ Link to comment Share on other sites More sharing options...
phutumsch Posted April 22, 2020 Share Posted April 22, 2020 Check your hazard switch, I think it's fouling on the pod housing, so not fully engaging of disengaging. Quote Link to comment Share on other sites More sharing options...
GRMAGNUM Posted April 22, 2020 Share Posted April 22, 2020 Have you tested with multimeter? Check at front indicator 12v on b/l neg is black, if no volts showing put multimeter neg tem on battery neg and test b/l for 12v if ok you have lost your earth on black , to check this put wire on black cable and touch earth on body or battery Ps make sure your ignition is turned on. ,and indicator stalk turned to side you are testing.

GRMAGNUM Posted April 23, 2020 Share Posted April 23, 2020 Having looked at circuit diagram it would seem to be problem between flasher unit or indicator stalk area, I would look at flasher unit and wires to it , this unit is fed via hazard switch in off position . Fuse feeds - hazard switch off position-----feeds flasher unit ----feeds indicator stalk which in turn feeds either right or left bulb. You need to check wires on flasher unit- three wires 1. Feed from hazard switch.2. Earth wire.3.Feed to indicator stalk Number 3 looks likely to be missing. Hope this helps. Quote Link to comment Share on other sites More sharing options...
GRMAGNUM Posted April 23, 2020 Share Posted April 23, 2020 Flasher unit should be behind steering wheel under dash and there is also a bulb check relay that looks like it is on accessories board behind fuses in drivers footwell !!!!! Hard to get too so try flasher tset first. Quote Link to comment Share on other sites More sharing options...
GRMAGNUM Posted April 23, 2020 Share Posted April 23, 2020 This is what it should look like, Quote Link to comment Share on other sites More sharing options...
paulbrem Posted April 23, 2020 Author Share Posted April 23, 2020 Well today's progress........... replaced my hazard switch with another one I had, indicator problem still same. With a massive amount of struggling (seat out everything wrecked near the pedals.) I have finally got to my flasher unit, which was cable tie up right at the top, all my alarm units are in that place too, I have previously had the dash off and done a manual conversion so I tidy everything up under there ? Its a right mess now. The flasher unit is making the clicking noise and I can feel the switch inside when the hazard switch is pressed. I will have to check wire continuity between that and the indicator stalk tomorrow. and see if there a test I can follow on net tomorrow, thanks for the input, Ill be back with more tomorrow.

GRMAGNUM Posted April 24, 2020 Share Posted April 24, 2020 Ok. If you go to stalk plug side you should have 12volts on pin number 1 , if not you will need to back track to flasher unit. If you DO have 12volts on pin 1 you could try putting a temp link between pin 1 and 2 this should make one side flash. Link between 1 and 3 the other should side flash. If you have 12v on pin 1 and nothing happening when linked you have broken wire between 2 and lights or 3 and lights Chances are only one will be not working ,you will then need to check wires from pin 2 or 3 to the actual lights You just need to keep methodically going though them. Remember you will need ignition On so be carefully when linking or you will of course blow fuses. Like I say multimeter check 12v on pin 1.

Yes both could work perfectly, I still it's fouling, have you tried it when it's dangling loose ? Another thing to add, your hazards work without the key don't forget.

paulbrem Posted April 24, 2020 Author Share Posted April 24, 2020 Big thank GRMAGMUN I have 12V on pin one, i have looped wires 1+2 and then 1+3 both times worked as expected but still with no power to either front indicators (the back and sides are OK). Think I need to find out what the relay does behind the fuse box in the foot well and check backwards from the front bulb connectors. The back of the car is jacked up at moment awaiting parts which should come today, tomorrow I'm gonna jack the front up and take the inner wings off to see whats happening with the loom, but the are fed independently from each other one wiring loom per side inside the inner wing. Blowing my mind lol Quote Link to comment Share on other sites More sharing options...

GRMAGNUM Posted April 24, 2020 Share Posted April 24, 2020 Hi, just looked again at circuit , do you realise there are SEPARATE fuses!! There is a fuse at battery end that supplies the HAZARD LIGHTS ! Hence why those work. Now , there is another separate 10 amp fuse in the drivers footwell if this has blown you will not get any turn signals but will still get hazard lights!!!!!!!! Take yellow 10 amp fuse out and replace with known good one. Quote Link to comment Share on other sites More sharing options...
GRMAGNUM Posted April 24, 2020 Share Posted April 24, 2020 Sorry not yellow should be RED 10AMP FUSE. Quote Link to comment Share on other sites More sharing options...
GRMAGNUM Posted April 24, 2020 Share Posted April 24, 2020 Have you checked again whether you have a 12v feed at front indicators and good earth Seems odd if side indicator is working cos they are on same line! Unless broken wire to front, but that would only stop either right or left not both. Quote Link to comment Share on other sites More sharing options...
paulbrem Posted April 24, 2020 Author Share Posted April 24, 2020 I've been replying on my phone an its not come through? Yep both fuses in foot well are fine. This is really is frying my brain, and I cant help but think its something ive done in the past. I've put a vidd up on youtube, as you can see that the end the sidelight is working and the sidelight shares the same earth so not an earth issue. only recorde drivers side but passengers side asme. I only noticed this as my car is nearly 'finished' and ready for mot an I was putting my lights back in but I have now got larger front mount intercoolers so the lights don't fit back in with the bulb holders how they are. Ive decide Ill have to make something, so going with LEDs that shouldn't have to be replaced. https://youtu.be/cwTUikVNz4A Quote Link to comment Share on other sites More sharing options...
GRMAGNUM Posted April 24, 2020 Share Posted April 24, 2020 It looks like you have lost live feed to indicator , if there is an open circuit because wire is broken or no earth it thinks the bulb has blown. Is this the same on passenger side?? Video only shows driver side. Because as you say loom is separate left and right so if both sides are the same you have lost either two live feeds or both have bad Earth !!! The side indicator should be connected somewhere to the front indicator you coulď try putting another wire in from side indicator to front, this will work , if it then doesnt work you need to give indcator fresh earth connection. Try running wire direct off neg on battery . Quick test I would do is using your meter, neg on battery check indicator for 12v if none try reversing put red lead on to battery pos black on indicator earth. This second test will prove you have good earth Quote Link to comment Share on other sites More sharing options...
GRMAGNUM Posted April 24, 2020 Share Posted April 24, 2020 Have a look at my drawing not brill but is correct. Quote Link to comment Share on other sites More sharing options...
paulbrem Posted April 24, 2020 Author Share Posted April 24, 2020 Yes video doesn't show passanger side but is same. Well I have put hazards on the with multimeter black lead to negative on battery. The multimeter set on voltage jumped from a signal to zero as it flashed but only 0.02v. When connect bulb holder earth direct to battery it still does not work. I connected the side indicators to the front but still used the earth cable from the light cluster and is now working as we knew it would with hazards but flashing quickly with indicator stalk as if there is a bulb out. Going to jack front if car up tomorrow and take it from there. Your help is much appreciated mate. Quote Link to comment Share on other sites More sharing options...

GRMAGNUM Posted April 24, 2020 Share Posted April 24, 2020 Looking where you are now I would just rewire from side light to front only two wires either side. easier than ripping loom apart, unless you find something obvious. Quote Link to comment Share on other sites More sharing options...
