sierrafery Posted May 14, 2015 Share Posted May 14, 2015 Did that happen with ignition on or off? Quote Link to comment Share on other sites More sharing options...

Nigelw Posted May 14, 2015 Share Posted May 14, 2015 Clock and radio share a common earth. Interior lights on a different circuit IIRC? Quote Link to comment Share on other sites More sharing options...
Discochris Posted May 14, 2015 Author Share Posted May 14, 2015 Do you know where the earth is for them? Quote Link to comment Share on other sites More sharing options...
sierrafery Posted May 14, 2015 Share Posted May 14, 2015 The other day stereo stopped working but flickered aswell as the clock wouldn't hold memory . I was asking if these symptoms were with ignition on or off...cos if it was with ignition on the problem could be from the ignition feed, the radio needs a permannent feed and an ignition feed to work so will do the clock lighting...so even if the main feed and earths are good if the ignition feed makes tricks that's what happens Quote Link to comment Share on other sites More sharing options...
Discochris Posted May 15, 2015 Author Share Posted May 15, 2015 Morning all I didn't think of the ignition feed to be honest what colour wire is it ? Thanks Quote Link to comment Share on other sites More sharing options...
Discochris Posted May 15, 2015 Author Share Posted May 15, 2015 Would it be fused? Quote Link to comment Share on other sites More sharing options...
sierrafery Posted May 15, 2015 Share Posted May 15, 2015 afaik these early modells used to have problems with the fusible links which are embeded inthe harness near the battery Quote Link to comment Share on other sites More sharing options...
Nigelw Posted May 15, 2015 Share Posted May 15, 2015 94' 300Tdi will have under bonnet fusebox, ign+ to radio white/green(from memory!) Coul be rad harness yellow as that seems to also be std colour. there are earths everywhere on the bulkhead, you could always add a new one, can never have enough earths!

Discochris Posted May 15, 2015 Author Share Posted May 15, 2015 Got the stereo and clock working now:) Still no interior lights and if I put bulb in resets the clock odd Quote Link to comment Share on other sites More sharing options...
steve_a Posted May 16, 2015 Share Posted May 16, 2015 This sounds like a bit of dodgy wiring I've seen before where someone mistakes a switched live, say lights, for an earth and things blow or stop working when you turn things on. I'd remove the stereo and check everything else, as that is the site of a lot of crimes against wiring... Quote Link to comment Share on other sites More sharing options...
