Won't start only clicking?

[Decentlemon]

Been trying to start my 1994 Yamaha seca 2... Had it hooked up to trickle charger all winter. Got a warm day took it out was fine for over an hour then on highway I started losing power. Pull over check gas which is fine but bike won't start. Got it home now it sounds like this. I tried jumping it to no avail. I believe it's the selinoid?? There is a clicking sound coming from the area next to the battery. Any thoughts??
