Hi all, Went down to see my brother last week and the bug ran fine down and around the marchers, after about 100miles I pulled into a farmers gate to say good bye and the engine stopped. Switched off and talked for 5mins...the engine would not restart and has not since then. The people at AA brought the bug home and I've had a preliminary look but this weekend will be taking it apart....to find the lost volts. One memo to myself remember to take meter and a bit of wire on runs...spanners are good for nuts but not electricity. Any thoughts I am beginning to think that a contact may have come off the ignition switch. Also when cranking the engine over the fuel gauge drops to empty and then returns to tank quantity, am i getting a stray earth? Ayrbugger

I am assuming that when you say the engine won't start, you mean it doesn't turn over at all? Or does it turn over but doesn't fire up?
Easy bits first: check your battery terminal connections. As in, take them apart, clean them up with some emery cloth or (worn) aluminium carbide (gently!) paper (or glass paper if you've got nothing else), remember to do INSIDE the cable ends as well as the posts on the battery. Rather than a stray short circuit you may be getting effectively OPEN circuit due to corrosion on the battery terminals.
This may not be the cause (though equally it may well be) but at least you need to eliminate it before you do further testing. By the same token, also check that your earth strap(s) are tightly fixed. Again, it may do no harm to disconnect them and abrade so as to remove any corrosion.
Assuming you have fuel to the carb then go for the electrics. After checking the battery as per cdb15 above then check the other 3 earth points around the car. Next do you have a spark at the plugs if no then focus on the dizzy
Hi all, Got my head engaged today and with relevant spares to hand got stuck in. The problem traced out to be a broken wire in the original loom, now remade,also a new coil fitted and she's running sweet as a nut. Job done. Hope to meet you all at the 50th /51st rally thanks for all your helpful pointers, remember when ignition fails sharply it's electrical, if it fails in splutters then it's likely to be fuel. regards Billy aka the Ayrbugger
