It charges through an electronic regulator and rectifier and has been giving trouble. Despite working on it off and on all week, I can't make it work properly despite changing every component.
I also have another 2 brush, 12 volt Lucas dynamo on another car that charges through a Lucas RB106 regulator/cut out (Morris Minor type). This has worked without any issues for over 10 years with no attention of any kind.
I have a new, old stock, Lucas RB106 cut out/regulator and I'm now minded to use this on the car where the electronic kit is giving trouble. I am aware that when these 2 brush, 12 volt conversions are done, the dynamo is wired differently, internally, depending whether it is to be used with an electronic regulator or a mechanical regulator. Electronic uses a 'Continental' wiring layout, mechanical an 'English, Lucas' layout.
My problem is that I am a complete electrical/electronic ignoramus and I need specific, easy to follow instructions as to how to change the 'Continental' wiring in the dynamo to the 'English, Lucas' layout. Any advice gratefully received particularly if it doesn't use big words that I won't understand!
Thanks in advance,
Steve
I am not familiar with using the RB106 with an Austin Seven dynamo, but I do have wiring details for the Dave Lindsley electronic regulator and for the AO electronic regulator. I do not recommend the AO system for an Austin Seven because it is arranged so that it does not start charging until the dynamo is up to twice the normal cut-in speed.
