After two quotes of around $500 for a replacement igniter, I happened to recall the phrase "goodwill claim" that I'd heard when pursuing my warped front discs issue. A dealer put my dead igniter through as a goodwill claim, and I got it for free.
While I can agree in the survival of the company aspect that Triumph corporate wouldn't be inclined to take a full page ad in the NY Times admitting to defective electricals, I shouldn't have had to ask for the magic / secret "goodwill claim", but there it is if anyone may need it.
If I had to choose one bike for a desert isle, it would indeed be a Speedmaster or America, but at the same time, I have to agree that some of the electrical design and install is less than stellar. The placement of the igniter over the hot engine, and some skinny little wires hanging out in the wind without loom or any protection from chafe, and too small of wiring that will not allow for the full potential of the charging system come to mind first. If I can wrangle my bike into a dry warm spot for the Winter, I'd like to do over a great deal of the wiring.
