Title: WTB Siba voltage current regulator
Post by: ohartmanno on December 09, 2014, 07:50:29 AM
I´m in need of a Siba current regulator for my Villiers 3T engine. As I know this part was used in Messerschmitt, Fuldas and Heinkels as well. Can anybody help? Thank you for your advice! Best oliver, mail: hartmann.zirkel@t-online.de

These are becoming a bit hard to get hold of, in working order. A problem, if originality is important. Otherwise you can use the Nosso regulator available new. It is a version of the Bosch regulator found on Goggo, Isetta and such. However it would work for you. It is not going to go straight into a Black Box however, as it is a wider design, as was the bigger Bosch item it copies.
There are several people now offering a solid state version of the regulator, placed inside an old regulator unit so it looks original. I have never used one and would make no recommendation of the units. I prefer, and have original stuff still. They are more expensive that the Nosso, in my experience. Though there are folk selling Nosso at silly prices. Trust this helps.

The one I think Al is talking about is the DVR2-S

There was. I forgot to bid on it. Ebay used to remind me, but all that got involved in blather and promoting left handed wombats, or equally daft product if you wanted a regulator, because there was some weird association in a computer numb nuts's head. Cannot be bothered with it, so I continually fail to bid on stuff. Its all to time consumingly boring.

If you find one I would advise fitting a fuse to prevent future 'burn' out , its a job - but well worth the effort - can supply a bit of info and paperwork if needed .

I would favour an electronic regulator over electro-mechanical any day- much more reliable providing it's been done right.

For those interested in reading more about solid state dynamo regulation I thought the following articles might prove to be interesting reading-

Providing its been done right. Its that nasty little phrase, isn't it? Many a micro have I passed with duffed electronic ignition. But I agree that if its done right, its better, though not fixable at the side of the road. There is only one way to find out, and there is a fair choice now. After you, sir.

Agreed.

It does help if you understand what is going on under the cover, and I think whilst many DIY restorers can stretch to most jobs, understanding the intricacies of electronic units is beyond many. It doesn't help when little to no information is supplied with the units in question.

I refurbished my Bosch control box some time ago and retrofitted one of Colin Archer's replacement items (is he still making them I wonder?) which is custom built to fit in easily. Not cheap, but well made. However the circuit is potted in resin, which means if something does go wrong, it's not an easy fix.

The information I posted above is the first I've seen of anything published online about a DIY approach, and there is also quite a bit of good information about how the mechanical units worked.
