Bit puzzled, bike hasn't been started in a few weeks as had to fit a new oil cooler (not standard, so had make a bracket eat, so has taken a while).
I wanted to start the bike to make sure I didn't have any oil leaks, put key in and turned ignition on, but there is absolutely no electrics! No dash, no headlight, no starter, no indicators...nothing

Figured battery was flat, and hooked it up to my optimate which charged it up and according to the optimate the battery is good. But still no electrics!
I have gone over all cables I have come into contact with and none appear to be loose and I have checked fuses which are all fine.
Is there any other part which could have failed which would kill all of the electrics??
Many thanks in advance!
