Hi All,

Bonneville starting problems.

Just checking if anyone knows of a way to reset the minimum voltage level below to 12.6 volts using tuneboy or similar.

I have an 09 Bonneville in London, used mostly daily and have been having constant non starting problems due to battery voltage dropping below 12.6v

I have just paid £56 to have the 'City Tune' so that the EFI systems shuts down immediately after turning the bike off. This was done 10 days ago and already I have had the same non starting problem so this has not cured it.

If there was a mod that set the low voltage threshold a volt or so lower then this would solve the problem.

I don't have off street parking, being in Central London, the bike is parked in the street so I can't easil plug the bike in to charge overnight, but have to remove the battery to do it.

This is the newest bike we have had and was supposed to be a good, new, reliable bike. My old 1984 BMW R65 was more reliable at starting.

I can't do the mod to the starter relay, parking it on the street and making it easliy nickable is not an option, even though I chain it and it is alarmed.

Any help Triumph?

I have a similar problem with a 2011 EFI. My cure has been to start using the choke, or a gentle twist of the throttle. The owners manual states always use the choke when starting, 2 clicks in cold weather and 1 click in warm weather, or with a warm engine. Doesn't fix the problem, but at least it always starts.

Exact same problem with my '12 SE. It doesn't do it every time but when it does I push the starter and it'll turn over once and stop even while I keep the starter pressed. I'll then pull out the "choke" one click and it starts right up, even when it's warm.

Is this something that reprogramming the ECU can fix ? I don't know why but I have never had this problem and I let my bike sit up for months at a time during the winter with no charger on it.
