Mystery fuse

The Triking started to show an ignition light and the battery was running low which it hasn't before. I have an alternator tester and this was not showing any charge coming through so I thought I had found the issue BUT.....

Whilst revving the engine to do the test I noticed sparks coming from an inline 30amp fuse connecting the positive battery terminal to the regulator.

The fuse holder is all melted and will need replacing but I can't see that a fuse between is specified on the wiring diagram.

Am I ok just to replace the fuse and holder or does this point to a bigger problem with the regulator or the Alternator?

Thanks in anticipation

Andy

Hi Andy,
That fuse has blown for a reason. I had the same on my bike and the failed reg/reg took out the ECU! As they're so easy to check, I'd disconnect everything from the reg/reg and check the diodes and output voltage to make sure you don't fry any of the electrics.
Andy.

Hi Andy,
This has been added to the build on Factory builds for the reason you have discovered. Please do replace the holder and fuse. I have retro fitted this fuse to my machine.
