Harry Flatters Posted June 7, 2002 Share Posted June 7, 2002 I have a slightly weird occurence with my ignition light. From cold, the light comes on with the ignition and goes out as normal once the engine is running (although it does need a good blip on the throttle to get it to go out the first time from cold). Then, if the engine is stopped after a blat (nice & hot) and I then turn the ignition back on I get no light. Everything works OK, car starts etc but no ignition light. It is always OK from cold. No loose connections behind dash or alternator. Any ideas out there?? Steve Mell PTM 88 Link to comment Share on other sites More sharing options...
Stijn LUYCK 1 Posted June 7, 2002 Share Posted June 7, 2002 A loose, slipping alternator belt that stops slipping once it warms up? Link to comment Share on other sites More sharing options...
Swiss_Tony Posted June 7, 2002 Share Posted June 7, 2002 Its easy to check. Are you about at the weekend? If so I can pop round. James Link to comment Share on other sites More sharing options...
stevefoster Posted June 7, 2002 Share Posted June 7, 2002 You usually hear a slipping belt and it would not cover the no light with ign. on before the hot re-start... Electrics in the alt. would be my guess. Steve My racing pics hereid=red> Hants (North) and Berkshire area club site hereid=red> Link to comment Share on other sites More sharing options...
EFA Posted June 8, 2002 Share Posted June 8, 2002 I'll go with Steve - a bad warning lamp winding or rectifier in the alternastor sounds likely. Next time you get the problem, ground the small wire on the alternator to the block and if fault is within alternator the light will come on. be carful not to ground the main charging feeds - that'd be a bad thing....

Alex Wong1697456877 Posted June 8, 2002 Share Posted June 8, 2002 NOT ALL 7's USE THE SMALL WIRE FOR THE LIGHT. Mine is hard wired to the battery. I know this because I forgot to attach it to the alternator once and it earthed on the chassis tube it was lying on. Within 10 seconds, the alternator part of the loom started smouldering and melted. When I disassembled it, I traced the melted wire back to the battery. Do not earth this wire! Link to comment Share on other sites More sharing options...
EFA Posted June 8, 2002 Share Posted June 8, 2002 Alex, You traced the lead from the other side of the ign lamp which does of course go to the battery. If your loom smoked, something else was wrong!

Harry Flatters Posted June 10, 2002 Author Share Posted June 10, 2002 James, Thanks for the offer, albeit it's Monday (only just got back to BC)! I'm inclined to go with Steve's alternator electronics. Can they be replaced or are we talking new/recon alternator here??
