Igniter On A America

The 270 degree motor has an ignition coil (£60) for each cylinder. So who told him the igniter has failed? Is it the same cylinder or variable? Furthermore, it could be the pick up coil ((£40 crank position sensor) on its way out.
Before shelling out £220 I would want a better diagnosis. The coils are notorious for going intermittent before total failure and can usually be checked for resistance values with a £10 multimeter......

Is it carbs or efi? https://www.triumphtwinpower.com/triumph-america-speedmaster-carb-ignition.php

 

Ok. Do both coils ignition on have battery voltage at the low tension +ve terminal ?

If the non firing coil doesn’t it would point to the igniter. Carb or efi?

 

I had a duff coil on my speedmaster (same engine and electrics) but if you swapped them and same result could ponit to igniter, but as said by Callumity you need to check all the other componentsfirst i.e. plug connectors etc.

I had a remapped TTP igniter on my speedmaster and it was a big improvement on the OE map.

 

Thanks for sharing this info Callumity, I take it the TTP products are a vast improvement over stock

 

It is the same Gill product but with an ignition curve designed for riders not regulators.....

 

That feed is from the igniter that chops it when it should fire..... live to other coil points to internal igniter fault.

 

Try some contact cleaner on the Igniter connector first and if still not there, try a resistance check from coil feed back to connector, pins 8 and 15 feed coils colours are yellow/black and yellow purple.

 

Sorry pins 8 & 14
