Before I strip the engine I wanted to get it running but I have no spark.

I have searched a couple of threads and found how to set the points but I have noticed that my magdyno doesn't have two wires coming out of the front of it.

Are these wires fundamental in producing the spark or do they just provide electricity for the rest of the bike?

I have a workshop manual coming so hopefully these type questions will reduce once I understand how these old bikes work.

The two absent wires will be from the dynamo part of the magdyno and will not affect the spark, or lack of.

My model G had this problem too, after studying the information i had (workshop manual etc etc) i realised that the magneto was toast in my eyes and beyond my capabilities. Rather than have it reconditioned i decided to fit a Thorspark conversion which has turned out to be a brilliant bit of kit. I'm sure there are people here with magneto knowledge, afraid i'm not one

I'll look up Thorspark, my plans at a later date is to make it as user friendly as possible, on my 61 Triumph Speed Twin I upgraded to 12v, larger stator, electronic ignition and Twin Leading Shoe.

Tonight was emotional did some points cleaning and fettling on my Model G it produced a spark and putting a drop of oil down the bore has brought the compression right up.

As I ran into the house arms aloft and announced this amazing achievement to the family I was congratulated most heartily (well the missus murmured "well thats good innit").

Onward and upward

Well done that man, on a dynamo bike I would always stick with the magneto, no matter what happens with the charging system you will get home and that counts for a lot.

Thorspark ----Nordic God of Plugs maybe ??

Thorspark is good?, But with a dynamo powered bike I am far happier with a good magneto, it's self powered and normally trouble free, a dynamo has great difficulty supplying enough power to run electronic ignition especially if used in traffic at low speed, with lights on it has no hope.

Just a thought but isn't there a company who can fit an alternator system as a replacement to the Dynamo innards ??.....that way you keep the looks but enjoy modern reliability ..
