Well it was the Alternator after all. Lesson learned. Thanks to Paddocks for getting one to me so quickly.

I had a 1962 IIA 2 1/4 petrol as my main vehicle some years' ago for a daily round-trip to work of about 50 miles on main roads and dual carriageway. It was great fun. Lots of members keep mentioning a top speed IRO 45-55mph. I'm out of touch with series Landys now, but I fitted an overdrive...

Thanks Vanny - that was the first thing I looked at, together with the connections on the ignition switch. The work I had done last week to bypass the immobiliser made me suspicious that an earth connection had come loose, or something like that. Your experience at least will give me something...

Thanks John_1987 - that's the conclusion I've got to. I hope to get a new Alternator on Friday. The battery was so flat this morning I couldn't jump start it and had to bump it into life. Apparently main dealers can't get alternators at the moment; they're on back order and none are available...

Hi Everyone - this will probably be some strange earthing problem but it's baffling me. From today, when the ignition is off the battery warning light remains on ... even when the key is removed. At the moment the Landy starts normally and the warning light goes out at you'd expect. As all...
