Mag-Dyno

 
We have developed this as a new, direct replacement for the Lucas MO1 mag-dyno.

A traditional Mag-Dyno for people who want to retain their original appearance and combined dynamo and don't want to rely on a battery charging system.

The Mag-Dyno was fitted on thousands of bikes ranging from the everyday work horse to the sporting BSA Gold Star's.

Brief Specification:

• A direct replacement for whatever system you are using now. 

• Self generating unit requires no battery.

•  Uses the latest advances in electronic ignition technology.

• Simplicity itself to time and no contact breaker points to maintain.

• Shaft and fixings manufactured in stainless steel.

• Sealed bearings for a long maintenance free life.

• Rotation: Clockwise or counter clockwise. 

• Available with either fixed or electronically advanced timing.

• Twin plug option available.

Key Benefits

• Strong reliable sparks for easy starting, reliable tick over and full power performance.

This is a replacement for the "tired" mag-dyno's that were fitted to hundreds of thousands of British bikes.  The BT-H, MD1R mag-dyno is for people who want  to  enjoy the benefits of modern ignition technology and be able to refit an original dynamo without having to upgrade their machines charging system.  This is an all new manufacture NOT a conversion to battery or renovation with a rewind.

This gives you all the usual benefits of a new BT-H magneto.  You get a new mag-dyno with electronic advance/retard, proper journal bearings mounted in sturdy steel housings and no contact points requiring adjustment or replacement.  It is supremely easy to time and because it is a magneto you won't be stranded if your battery or charging system fails.  A very small, external, high tension coil is supplied with this instrument.  This can easily be fitted in any suitable out of the way place on the bike.
Your existing dynamo fits as standard to provide your lighting power.
The mag-dyno will be supplied with a dynamo clamping strap and a blanking plug in the advance/retard cable hole.  You may remove the blanking plug and fit your existing adv/retard cable etc to retain the original appearance.
N.B.  This unit at the moment will not work with some early Alton generators. Paul at Alton has produced a solution so if ordering an Alton from Paul Hamon specify that it is to be used with a BT-H Mag-Dyno.

I thought I would drop you a line to say that I received the Mag and have  
fitted it. I took my time so I could go about it in the best way to suit  
me, hence the delay. 
I set the timing to specs I could glean from other GS owners and from  
original tech info, then followed your instructions. I can't tell you how  
happy I am with the result. I am no longer terrified of starting the  
beast. No more savage kick backs, worries about getting advance and retart  
just right. No more worries about not being able to start it. Six kicks  
and you start to lose it, frustration, embarrassment and all your mates  
waiting around. It would put me off riding it a little I think, wondering  
how many times on a ride I would have to stop. 
From the first moment it started first kick. It is like a pussy cat to  
start now, but still has the cracking pace and sound. It looks original  
and all round it is an excellent result, so thank you very much for a  
brilliant unit. Thank you for the prompt back up support as well. 
I thought my experience and how I went about the process would make an  
interesting story for the GSOC magazine. Any thoughts on this?

Regards 
Raymond Pobjoy.
