2013 EFI Bonneville electrical issue: engine cuts out while in motion
Mag wheel Bonnie. Happened last week and has been sitting in the garage ever since. I was riding at about 25mph and the engine cut out. It came back after a half block of coasting and I made it home. I canít remember whether I pressed the starter, or not. But, while the engine was out, so was the entire instrument cluster. When the engine came back, so did the instruments.
Prior to this, there was one morning where I saw a brief flash and everything went out when I tried to start the bike. After that happened, I just cycled the key off and back on, and everything fired up when I hit the starter. No blown fuses ó not sure what could have caused the flash.
Iíve metered the battery and itís fine. 12.8v.
Last year, I installed relays, to bypass the starter terminals in the very corroded ignition switch. I followed the guidelines published in this forum (I forget who the user is who did the write-up), and everything worked great. But, I suppose that could be the source of my issue.
Where should I start looking and what tests should I be conducting?
