After not having ridden the bike for more than 6 months today I put in a new 6v battery and started the bike. It took 3 kicks and the engine was up and running. Unfortunately there was no charging of the battery indicated.
As the magdyno was renewed a couple of years ago and a well working charging system 6 months ago I do not expect any technical problems. Is there any "procedure" necessary to "motivate" the dyno? I remember some kind of "electric vodoo" I had to perform at the regulator of my 58 HD after having disconnected the battery. Sorry for my stupid wording - I have actually no clue of electric theory ..
It is unlikely that you need to do anything special to the dynamo.
It may be more a question of corroded contacts or such.
The dynamo needs just a very weak remanent magnetism to start up and if it worked 6 months ago it should do so now as well.
The Instruction and Maintenance manual gives some guidance on how to test your dynamo.
If that is OK you have to look for other options in the circuit and voltage regulator.
If it an electronic unit it can hardly be anything other than a bad contact somewhere.
The electrical system is fairly simple but can be a bit puzzling if electronics is not your "thing".
thx for your message. After having read the respective paragraph in the manual I decided to try it again. I removed the cover of the regulator and started the engine. At low idle revving of the engine there was no "action" visible of the regulator. But if the engine revs higher suddenly one of the switches of the coils closed a circuit and the amperemeter indicated charging.
So I expect that the charging system will work under running conditions as it did the years before.
Unfortunately when I was taught physics at school I wasn`t aware of the relevance of this subject for my later life ;-)
No computer system on a WD16H so the basic learned at school should be sufficient!
