housebuilder Posted December 9, 2012 Share Posted December 9, 2012 I had all my lights working but noticed the rear drivers light was out. I thought it was my dodgy connecter crimping but all is sound. I have sinced noticed that the indicator is also out as is the number plate light. bizzarely the fog light works and so does the brakelight which is in the same led unit as the rear light. swapping the power over the rear light works when wired up to the brakelight circuit so I can rule out earthing issues. do I fear the worst and start looking for damaged wires right along the loom?

pete g Posted December 9, 2012 Share Posted December 9, 2012 unplug the rear connector and check with voltmeter Quote Link to comment Share on other sites More sharing options...
Andy Rob Posted December 9, 2012 Share Posted December 9, 2012 Had problems with my rear lights at various stages too Housebuilder. If you have had them working at one stage, it's unlikely to be the loom. My faults lay in bad connections within the connector blocks. Redoing them worked for me.

housebuilder Posted December 9, 2012 Author Share Posted December 9, 2012 There is definately no power there. Mate borrowed the voltmeter hence the wire swap to check the unit. Will check when I get my tools back. grrr. The fact they were working makes me wonder whether i have caught a few wires somewhere as it seems odd that the rear light, indicator and number plate light have all gone at the same time.

pete g Posted December 10, 2012 Share Posted December 10, 2012 fuse board is next check. .have know them to be corroded up. Quote Link to comment Share on other sites More sharing options...
Rhett Turner - Black Country AO Posted December 11, 2012 Share Posted December 11, 2012 The offside tail and number plate light are on the same circuit I believe. (fuse 2 set A). not sure why this would effect the indicator though. Quote Link to comment Share on other sites More sharing options...
housebuilder Posted December 11, 2012 Author Share Posted December 11, 2012 Thanks both. Fuses all ok and tested fine. no to number plate light or indicator or rear light on drivers side showing on the voltmeter. despite ten miles of convoluted tubing and only two runs up the drive its hard to think it can be anything other than damage only thing i have done to the car that i can think of before noticing the light is finishing the tunnel and trim. I suppose carpet out and a look to make sure Ihaven't caught anything with a stray drill or rivet would be the palce to start? cheers Quote Link to comment Share on other sites More sharing options...
Andy Rob Posted December 11, 2012 Share Posted December 11, 2012 Yep, the old one step forwards and two back syndrome. Sounds like it would be worth a look, particularly if that's the last job you did before they stopped working. Electrics can definitely be one of the most challenging and infuriating parts of the build.... Good luck with it Quote Link to comment Share on other sites More sharing options...
housebuilder Posted December 11, 2012 Author Share Posted December 11, 2012 cheers can't believe it was all working only to have this problem! I really can't remember whether it was working after the trim fit or not but it seems a logical place to start sorry to hear about the test particularly as I saw a post somewhere where an Inspector said he had never known a kit car have self centering steering before giving it a pass! I heard somewhere that keeping the tyre pressure low might help? Quote Link to comment Share on other sites More sharing options...
Andy Rob Posted December 11, 2012 Share Posted December 11, 2012 Thanks, disappointed - but could have been worse, plus my retest will be an evening next week, so might just get there this year yet!!! I have been doing some work on it tonight, it's on the IVA thread, but tyre pressure and toe adjustment seem to be the way forward!! Quote Link to comment Share on other sites More sharing options...
housebuilder Posted December 17, 2012 Author Share Posted December 17, 2012 Can't see anything obvious. lot's of head scratching but no fix. anyone got any ideas? thanks Quote Link to comment Share on other sites More sharing options...
CSRacing Posted December 17, 2012 Share Posted December 17, 2012 If you have any spare cable i would test the continuity of each wire one by one full length ideally checking the resistance of the circuit, as might even be cable that has been crimped against the insulation only Do you work in London? as i could lend you a tool that adds a pulse to the cable, and you can use a probe to listen for the pulse, you just trace the cable length and when the beep stops the break is there ;-) Quote Link to comment Share on other sites More sharing options...
