YBR125 Takes time lights to come on after turning key

[christs]

I've got a Yamaha YBR125 2010 model.

Everything was working perfectly until one day I turn the key to ON, and no lights come on (as in engine warning light, neutral indicator light etc). After around 10 seconds they came on, and you can use the ignition/start switch to turn on the engine like normal. I turned it off as this never happened and turned the switch, and the lights came on instantly. This now happens on and off, and the time varies - surely if there was a loose connection it would not turn on at all - or could this be linked to me dropping the bike (rarely done).
Has this happened to anyone else? It's not a massive issue as long as it eventually comes up but I fear one day it won't which is a big problem depending where I am. On the handbook it says 'if the warning light does not come on initially have a Yamaha dealer check the electrical circuit.'

TLDR: Turn key; nothing/nolights come up until after couple/ten second; why is this/solutions/happened to anyone else?

Many thanks - any ideas or solutions welcome!

Check your earths / relays / battery connections and if all else fails ... get the battery checked for condition.

Wrong section. Post in The Workshop, you'll get a better response. This is for news and issues that affect motorcycling not issues with broken motorcycles.

Probably a loose connection, but check your battery as well.

If it's non-sealed wet cell, check and top up the fluid with distilled water.

Get a cheap multimeter (£5 from eBay is fine) and check the voltage across the terminals some time after riding it.

If it's under 12.6V, charge it then leave it for a while and test again.

If it's still under 12.6V, replace it and fully charge it before use.
