Alarm issues - Fuse 7 blowing

I have a low mileage 2007 DuperDuke with a factory fitted 'Gemel' alarm. Recently it has begun to blow Fuse 7 (Main Relay) while starting the bike. The start-up sequence is as follows:
1) the kill-switch is in the 'On' position
2) switch the ignition to the 'On' position
3) hit the button on the alarm remote control
Instead of the display lighting up and the rev counter doing a full rotation, the display remains blank and the 10A fuse in slot 7 blows. The bike still starts when I hit the start button and it runs as normal (with no display however - nothing at all). With the fuse blown I still need to use the alarm fob to disable the alarm for subsequent starts (there's no audible chirp confirming this action however).

Replacing the fuse and retrying has the same result and just blows the fuse (Albert Einstein described Insanity as "doing the same thing over and over again and expecting different results"). I'm tempted to remove the alarm (which seems to be directly related to the issue) but I believe I need to get a blanking plug to complete the circuit.

Has anyone else encountered this issue before? If so how did you remedy this?

I had a similar problem when I fitted the race mask and associated wiring loom, I believe the power on mine comes from the clock fuse / circuit, I'm not sure what about it was causing the extra draw but the only way I could fix it was to put a 15amp fuse in, I swap it back to a ten when I put the std headlight back on just to be on the safe side.

I know sense says that you shouldn't ever put in a higher rated fuse than what is designated and for that matter I definitely don't want you to accept my experience as gospel that it will definitely be ok for you to do the same, however, it has worked a treat for me over the last two years with no issues whatsoever, but if you do choose to try the same then it must be at your own risk.

Thanks for the info. I'll give the 15A fuse a try but I'm concerned about its long-term use as it might allow increased current to flow and damage the wiring/some other component.

I'm still curious as to the sudden cause of the issue. Your issue seemed to be directly related to the headlight mask change but I haven't changed anything.

Keep you posted as to progress.
