martin b Posted September 9, 2006 Share Posted September 9, 2006 Broke down at 5.30 this morning on the M25 en route to Wiscombe, suddenly had several complete electrical failures lasting a few seconds followed by a more permanent failure where I couldn't get power to anything . After a few minutes I could get the ignition lights and headlights working but any attempt to start the engine resulted in losing everything again. After recovery home I tackled the Fia switch, an older version located next to the steering lock, cleaned contacts and generally pulled all electrical bits around ensuring good connections, went for a drive round the block and all seemed well but couldnt resist a second circuit and the fault came back again ( grrr) Car is a bdr engined hpc Any thoughts 🤔 as i'm a bit stumped now Ta Martin Link to comment Share on other sites More sharing options...
Normans_Ghost Posted September 10, 2006 Share Posted September 10, 2006 Martin, almost certainly the 2 large Lucar connectors on the alternator. Pull them off and pinch gently together with pliers. Refit. If that's it then the permanant cure it to fit new ones (the present (was going to say current) ones have lost their tension due to heat). Get a piece of heat reflecting material and stick a bit the the terminal block. Don't cover the air vents.

JampJ Posted September 10, 2006 Share Posted September 10, 2006 I would resist the temptation to go round all connections, if you do that and it's then OK, you don't know where the fault was, or still is.Try one thing at a time.

martin b Posted September 10, 2006 Author Share Posted September 10, 2006 Many thanks Norman, hit the nail on the head Perhaps I should have posted on here earlier 🙆🏻 would have saved me fruitless hours. John, I appreciate the concern, I can picture from my previous post you imagining me frantically pulling away at various wires but I did try to be more methodical 😬 Thanks again Martin Link to comment Share on other sites More sharing options...
Mick Day Posted September 10, 2006 Share Posted September 10, 2006 Think you might find it's the FIA switch thats to blame. Link to comment Share on other sites More sharing options...
Normans_Ghost Posted September 10, 2006 Share Posted September 10, 2006 Mick, I thought that the first time it happened to me. It's the two large Lucar spade connectors on the back of the altenator. They are the same circuit and on some alternators it's a single wire (save a few grammes!) The number 1 branch of the manifold heats these to the point that they lose their "spring" and whilst are on the spade are so lose they make no connection or keep making/breaking.

Support Team Shaun_E Posted September 12, 2006 Support Team Share Posted September 12, 2006 Martin - sorry you didn't make Wiscombe but glad you've got the car sorted now. It meant there was only me and Simon Rogers in class 5 - you can gess what the placings were! 😳 Yellow SL #32 Edited by - Shaun_E on 12 Sep 2006 08:55:24 Link to comment Share on other sites More sharing options...
