I was riding on some nice two lane when Trusty Rusty just shut down. I pulled in the clutch and managed to coast the bike off of the road and into the shade of some trees. A bit of head scratching ensued. Pressing the e-start resulted in nothing but quiet, so something electrical was amiss. Kicking the bike showed good compression, but no start. I opened the fuel tank and it was half full as it should have been. I pulled all of the fuses and none looked blown. So I resigned myself that I would have to do some deeper electrical troubleshooting on the side of the road.
I do have a small test light in my tool roll as well as a copy of Trusty Rusty's electrical diagram, so armed with those, I started at the beginning. Testing across the battery looked good, so I moved on to the fuse box and checked for power on both sides of each fuse. Lo and behold, the ignition fuse only had power on one side - I was not expecting that! The fuse looked fine, but it must have some internal contact issue that isn't visible. I had a full set of spare fuses with me, so Trusty Rusty was back in action once I replaced the ignition fuse.
Here is a picture of the problem fuse on the bench after I got home - looks like a good fuse, but it is an open circuit when checked with an ohm meter. This was not some no-name fuse either, it was made in Japan by Pacific Engineering Corporation. Live and learn.
