Question about 2005 Suzuki Boulevard C90
I have a '05 C90 Boulevard and began to have a few intermitent problems with the ignition switch not functioning. The battery was checked good by a battery specialty shop. I also hooked up a car battery in line with the battery on the bike to remove all doubt that it was a bad battery. All lights come on, horn sounds, etc, but nothing on the ignition. If I hold down the ignition and flip my kill switch from off to on, it does actually try to crank over for a second but then goes silent. Took it to my local Suzuki dealer and they claim to have tested all circuits with no issues and are now telling me that my "ECO" may be the problem which is a $1,000 part! Please help!
The ECU will not cause this symptom. They are giving you a line.
The link between the starter switch and the battery and the starter motor is pure electro-mechanical. The ECU covers how the engine works, electrically, things like timing, etc. not the starter motor.
The fact the bike starts to crank then stops says that there is at least a rudimentary path between the battery and the starter.
Just by the starter there will be a solenoid that controls the starter. It has a couple of screwed-down cables - those are the main power cables that feed the starter. You can bypass the solenoid by directly connecting those two cables - this will fore the starter to rotate, regardless of what any ECU says. I would perform that as a check but be careful - there is a lot of power going through it. Be careful not to touch the two terminals via the threaded portion of the screws that hold down the cables - only touch the bolts or you may weld a notch in the threads - it will make it difficult to remove if it is faulty.
I would normally use a single jump lead - connect one end to the nut holding down one lead, then momentarily touch the other nut - if the battery is good it WILL turn over. This is making the most basic of connections in the ignition system - connecting a battery to a motor - it can't fail if all is good and will certainly give you an indication of whether or not the battery is up to the task.
I would seriously reconsider your choices in mechanics, though. This is a basic test they should have performed.
