skodajag Posted May 22, 2020 Report Share Posted May 22, 2020 I’ve had two faulty voltage regulators in recent years. They work for a while then cease to. Has anyone else had similar problems? I think the ones currently being sold all come from the same source, ultimately, and I’m reluctant to order another. I’m told that there is someone in the south of England who restores original Lucas ones. Can anyone advise me on how to find him? Quote Link to post Share on other sites
Charlie D Posted May 22, 2020 Report Share Posted May 22, 2020 (edited) You can buy electronic ones from eBay. They will probably last forever as they don't have mechanical parts in them.

RobH Posted May 22, 2020 Report Share Posted May 22, 2020 (edited) Some confusion here I think. Charlie's post is referring to the instrument voltage regulator which sidescreen cars do not have as the instruments are a different type from the later cars. Since the query is in the sidescreen technical forum can we assume you are referring to the dynamo regulator? Problems with the replacement dynamo control regulators seem to be not uncommon - probably due to the pattern parts using sub-standard materials in the contacts. A lot of people have fitted alternators anyway which eliminates this problem but if you want to retain a dynamo and cannot find a refurbisher, the link below is to a company that can supply an electronic regulator replacement which I understand will fit inside the original lucas regulator box to retain the original look. http://edsltd.ddns.net/products.html If you want a go at fixing your own this is a how-to-do-it guide. https://www.mgexp.com/phile/3/191288/REPAIRING_THE_STANDARD_RB106.pdf Edited May 22, 2020 by RobH Quote Link to post Share on other sites

Richardtr3a Posted May 22, 2020 Report Share Posted May 22, 2020 Hi. I had an obsession with the RB106 for a long time. The new ones use reclaimed copper which is not good quality. It does not matter who is selling me last long. I had mine overhauled by an electrical company in the midlands Cox Auto Electrical who have an expert. I had a few done for stock in case they gave up. I would be pleased to send you one in the company sealed plastic bag. Send me a pm. Thanks Richard & B Quote Link to post Share on other sites

skodajag Posted May 22, 2020 Author Report Share Posted May 22, 2020 I’ve just sorted through a box of spares compiled in 1973. Found an old unit which I didn’t know I had. Cleaned up all the contacts and terminals and ......it works, despite being unused for at least 47 years. There’s a lesson (or two) there. Quote Link to post Share on other sites
skodajag Posted May 22, 2020 Author Report Share Posted May 22, 2020 Richard - tried to send a PM but get a message to the effect that you can’t receive message. Sorry, it’s probably down to me but I can’t find a way around it. Quote Link to post Share on other sites
Charlie D Posted May 22, 2020 Report Share Posted May 22, 2020 Sorry about that. My 3A has later instruments and an alternator, so I never thought about the dynamo regulator. I did think it a bit odd though that there was someone who refurbished instrument voltage regulators. I spent half an hour trying to work out how they would do it. (Did not come up with an answer.)

Richardtr3a Posted May 22, 2020 Report Share Posted May 22, 2020 Skodajag, I have cleared my inbox to make enough room for more messages. I am out in the garage for the next 2 hours. Please send a pm Thanks Richard & B. Quote Link to post Share on other sites
