Indian Chief Bj. 1948
It is also possible to install our Dynamo B on Indian motorcycles.
There is space, but the remaining space must be filled, as our Dynamo has a diameter of 76.00 mm.
All Indian models work with chain sprockets with a 6° cone, just like our Dynamo B.
Here is an example from our customer Hans from Holland, who has installed our Dynamo B on his
Indian Chief from 1948.
If you need any further assistance, feel free to ask!
Here is a short video from our customer Eric from Holland.
You can see our Dynamo B 6V/70W installed in a Moto Guzzi Lodola 175 cc Normale.
Our Dynamo B can also be installed on a Moto Guzzi Lodola 325 cc Gran Turismo.
You just need to remove the BMW R35 V-belt pulley and install the one from the Guzzi.
With the original Guzzi electrics in 6V, you don’t have to change anything.
That’s all; as you can see, it works perfectly.
If you need any further assistance, feel free to ask!

The dynamo was installed together with a new wiring harness.
Installation time is about 4 hours.
It is simple and can be installed without changes to the original wiring diagram.
This dynamo generates power even when kicking, and the indicator light goes out immediately.
The motorcycle must almost stall for the indicator light to start flickering.
The dynamo works great at both low and high RPMs!
We tested our dynamo with a small 3.2Ah battery, and everything runs without problems.
It is truly an excellent alternator that we can highly recommend to everyone.
Just like all our alternators available in 12V and 6V.
The workmanship is really of very high quality.
Our modern generators come without carbon brushes.
This means there is no mechanical wear. The design corresponds to the original.
Therefore, no modifications to the vehicle are necessary. Almost nothing needs to be changed in the wiring harness
either.
All our Dynamos B are protected with polymer fuses made of bimetal!
The electronics are thus almost 99% protected against improper installation.
The destruction of the electronic regulator is almost impossible.
We have designed our new regulators so that you can also ride without lights.
The alternators generate as much voltage as needed through the new regulator.
No excess energy is produced.
Intelligent regulators!!!
Our Dynamos B are also popular for Lanz Bulldog tractors.
