It shows chec because the ignition fuse blows.
Upon changing the ignition fuse, the bike runs fine.
I'm pretty sure that any competent mechanic, such as those employed by this garage, would have checked those wires without a second thought.
The mechanics have been in contact with Suzuki's tech support team throughout the duration of my bikes time in the garage. If anybody should know what is wrong with it, it's the people who built the bloody thing.
The trouble is, there is nigh on bugger all left to check. Not a single broken wire or faulty piece of hardware has been found.
I will be giving them until the second week of October to fix it. At that point, if they still have yet to find an issue, I will be returning the bike for its current market value.
Then I'll probably buy a Veek.
