My friend is restoring a Triumph Tiger T100 -61 and should need a correct electrical diagram. We have a Haynes reapair manual, where its a lot of different diagrams, the problem is just that we dont know which is correct for his bike. The serial number is H22455. What does the H in front mean? There is several diagrams in the manual that should include this number, but there are other letters, for ex.KD in front.
Does anybody know any good link that could solver out this make number/model/year problem, and were we could download a electric diagram, which for sure is correct to this bike?
Grateful to all tips!

Greetings Mikael & Tore Finland

This is an early unit construction 500 and should have the ignition points in a little mushroom behind the left cylinder.
The H denotes a unit bike made between 59, I think, and 68. In 69, the alphanumeric system was introduced, with the H for the 500s and DU for the 650s replaced by two letters which denoted the month and year of manufacture.

Hi Guys, yes Mecchanica the 'H' is for 'C' range twins and as you say 'DU' for 'B' range twins.
Your bike is a T100A and built April 1961 it has ENERGY TRANSFER ignition.
Using an RM 13 / 14 pegged alternator, AC ignition, horn and rectified DC for battery and lights. You guys in the States are familiar with Joe Lucas ET ignition :(

And that should have been "in a little mushroom behind the RIGHT cylinder".
ET ignition = energy transfer.....it transferred it to someplace in the universe, sometimes even to the spark plugs.

Thank you very much folks for your help!
I did not know much in the beginning about this bike, or old triumphs generally, because it isnt my bike. It seems that it been modified quite a lot trough the years. Obviuosly it should be the bathtube-fender, which it is not now. Are these sheet parts hard to find? And the engine is switched into a 350cc, according to its motor number. Are these engines totally different, or is it perhaps only different cylinders? I mean, if you change the cylinders, heads, carb etc so it would only be
the punched numbers that do not match to a 500cc T100, maybe you could live with that?

Thanks again, Mikael, Finland
