So I'm cleaning up the wiring and giving everything a good look over and after having to work a bit to get the connector to the main fuse / starter relay off it was clear why: the plastic on the fuse was melted into a little ball and the connector didn't look much better on the inside.

I assume this was from poor contact in the connector or the fuse holder. Luckily it seems the fuse holder assembly is available and not too bad at $20. However, the connector on the main loom seems like a harder case. I just got a bunch of those Sumitomo connectors from cycleterminal.com, but since this includes the fuse cover it must be a super special part. Anyone have a source for them?
Thanks,
