Did you use a Typanium Recitifier? There should be no problems unless it is a used one. All the new ones I havew used just "bolt on" .. there are 5 wires. Check to see if you don't have a grounded wire some where.. try it with the head light off.. I usually wire my bikes to start with no head light with a 3 way switch.. once running I can then turn the light on. Go through an check all your wires again, you might just have a bad connection somewhere.. here is an excellent site .. Jim http://www.raskcycle.com/techtip/webdoc16.html

Hello, your Triumph needs to have good spark and clean spark plugs, the battery fully charged.
The carbs need to be adjusted properly. This will make kick starting much easier & the bike will also run better. Choke it when it is cold, after that the choke should not be needed. Here is video showing how easy they will start --- on the first kick. I hope this helps.

You need to check which of the 2 things that can cause that: missing fuel or missing spark is the one in your bike.
For that try to start the bike several times then remove the spark plugs. Now look at them - if they are black or dirty then replace them. Try again and if now they are really moist then you have a missing spark and you will need to diagnose the ignition system: start with the battery (make sure is full) then the key contact (see is it powers the coil when the key is turned) then the high tension leads and finally check the points.
If the sparkplugs are dry or barely damp then check the fuel filter and clean the carburetors thoroughly.
