Ok, so my FL2 2007 GS wasn't very happy. The alarm was activating randomly almost everyday recently.
I did the usual and searched the forums for ideas, and checked them all out.
But couldn't find the problem.
Until the other day, when, whilst driving home the dash suddenly started to say 'bonnet open'!
So i said in delight... 'got you, you little !'

Ordered a new bonnet latch (with switch), once it arrived, 30 mins later all changed.

No alarm randomly sounding since... very happy again

As the forums state, the replacement latches have a very different microswitch arrangement. 2002 Honda VFR800
