America No Spark

Reevo · Nov 13, 2019

Hi all
Nothing wrong with my tiger it’s my brother’s 2004 America
The problem is it’s not sparking on one cylinder
Checked leads coils plugs by swapping over so the problem is before the coil but it’s fine on the other side
Cheers in advance trumpeteers

270 degree engine consistently misfiring on the same cylinder despite switching coils and HT leads?

The crank position sensor is triggering ok and so you can rule that out. The coils and leads are working when switched so it MUST be the igniter or the low tension lead to the non firing cylinder. You can do a continuity test of the lead by pushing a pin through the insulation and taping up the wound afterwards.

The cheapest source of replacement igniter is £234 https://www.triumphtwinpower.com/fire-starter-performance-igniter-unit.php

Sadly they can really only be tested by substituting a know good one.

And they are a really nice and professional company to do business with. Mine cured my 2006 Scrambler problem! Highly recommend them.
