…Or equal?
I know that this has been done before, but I also know it is not a direct drop-in fit. So I would really like to know what Bosch (or other) item is needed here (maybe p/n? or where to order?), and also what modifications are demanded?
Thanks a lot in advance!
Michael

Hello Michel,

This is possible and I have seen done many times.

The difference with the internal dynamo electric connections are basically in 1 wire.

Please see the link for electric scheme.

Shalom Noam,
Thanks for this reply.
I looked in the link and it is clearly stated that it will not function on a Lucas system. If you know more regarding the demanded modification - I will be happy to hear it. BTW - this is an electronic solution (which is fine of course and I prefer them over mechanical ones).

Shalom Micha.

Yes, correct.
The "Bosch" regulator in the article would not function if it is install on "Lucas" systems,
This is why you need to first modify the "Lucas" generator to operate as a "Bosch" unit.

The generators (dynamos) are all the same, basically.
The difference is withe the electrical wiring inside: The FIELD connections.

If you inspect the 2 schemes on the link, you can see that in the "Lucas" type,
The field coil is grounded at one end, and the other end is the (F) port,
(there is only 1 field coil in the BSA, so just ignore the 2nd..)
Whilst for the "Bocsh"- one side of the field is connected to the (D), (A brush)
And the other side also functions as (F) [Called (DF) for "Bosch"].

Please note that electronic regulators are not forgiving like the mechanical ones,
And if you connect it wrongly- it will probably burn,
So first you must check if your regulator is made to work at Lucas or Bosch configuration.

Usually there are dynamo diagram which comes with the reg'.

Once installed correctly, the electronic regulators are usually very reliable.
I use one for 10 years with no issues, but you must note:

1. You must run it with a battery, or at least a big capacitor, ("Battery eliminator")
2. A switch is needed, in order to disconnect the barrery when not in use,
Otherwise the battery would drain flat in 1-2 days, as the "Cut out"
On the electronic regulator is not a total "On-off" switch like on the mechanical
ones.

There are diodes preventing the flowback from the battery,
But diodes as a normal inherent leak back.

Good luck !
Noam.

If it is just a voltage regulator that you require, then I can recommend a DVR2 solid state regulator from Dynamo Regulators.

It fits neatly into the shell of the old Lucas regulators.

Decide what polarity you want to flash the dynamo to and then buy either a negative or positive earth regulator.

You can run either 6v or 12v using this regulator.

Pat

Yes,

I join to the recommendations above.
My regulator is also the DVR2, inside a "Lucas" shell.

When I bought it, some 10 years back, I was originally sold by "MTML".

Noam.

Can't understand if the price includes postage or if another 53 P should be added?

Hello Micha.

Do you mean- for the regulator?

If you chose "Rest of the world",
You will be redirected to the payment, and it is 54GBP
Shipping included.

Cheers,
Noam.
