Is the Bonneville 790 ignition control unit defective?
2006 Bonneville 790, No Spark, Ignition Control Unit Defective? This site uses cookies. By continuing to use this site, you are agreeing to our use of cookies. Learn More. Good afternoon everyone! I would need some help… My girlfriend bought a lovely bonneville 790 from 2006 (carb model) 8 month ago. The bike had around 3000 miles on the clock.
How does the spark igniter work on a Bonneville?
The spark induced fires in both cylinders – one approaching top dead centre on compression, the other on exhaust (so called lost spark). The igniter reads engine speed from the signal and applies the appropriate advance from the throttle position sensor.
Where is the pick up coil on a Bonneville?
However, the more likely culprit is the pick up coil which is also much cheaper. You should get about 570 ohms resistance measured at the connector tucked up to the RH side of the battery under the side cover. Have you also checked to see if you are getting battery voltage to the +ve side of the coil?
What does no start no crank no click mean?
If you have a late model GM vehicle and turn the key only to hear nothing, you’ll most likely think you have a dead battery—and you may. But a no start, no crank, no click condition can be far more involved than that. In the old days, power flowed through the ignition switch and down to the starter solenoid. Not anymore.

Where is the igniter on a 2006 Bonneville?
Well you are right, outside of an electronic lab the igniter can really only be tested by substitution. However, the more likely culprit is the pick up coil which is also much cheaper. You should get about 570 ohms resistance measured at the connector tucked up to the RH side of the battery under the side cover.
Are there any problems with my Triumph Bonneville?
The bike had around 3000 miles on the clock. Everything was fantastic until the bike start to manifest some intermittent problems: rough idle and poor acceleration (hole in acceleration at low rpm, staling…). She went to a Triumph dealer, they check the bike and did not find anything (intermittent problem). They done carburetors synchronization.
