Hi folks thanks for the replies.
The problem is that the blue High beam indicator light on the dash is working intermittently. No problem with the Lights themselves. Have only had the bike 5 weeks and took it back under the 3 Month warranty. Workshop checked all the switch gear up on the handlebars and said they couldn't find a problem so would order a new relay to be sure. Problem is they didn't actually look at it and apparently Yamaha say it could be one of two depending on what is fitted. They asked me to verify the Number on it, I just don't know where to look for it. Have been under the seat near the Battery/fuses, but before I start randomly taking panels off, I was hoping someone might be able to point me to where on the bike it sits. This is where I got the choice of numbers (5VK30 or a 5EA02).
Cheers
Mike
The blue indicator lamp is wired in parallel with the high beam bulb through the dashboard, there is no relay in that circuit
If the high beam stays on and the blue indicator lamp is intermittent then the circuit to focus on is the one going to the dash and it is most likely due to a bad connection, due to age. Simply opening and closing the plugs feeding the dash will possibly make the difference. Unless the lamp holder for the bulb in the dash is corroded too.
This is the high beam indicator circuit, highlighted with a red line, the bulb is circled in red (at the dash cluster)

The connectors up at the front can get the worst of the weather and easily corrode. I open and reseat all connectors on all my bikes annually, as a precaution. A spray with a contact cleaner and lubricant keeps them clean. If you use something like Caig Deoxit red formula then it usually stops any further corrosion
You don't need to know anything about electrics to do this, just carefully unplug and reseat any connector you come across when you're working on an area of the bike. The 900 has a lot of plugs/sockets underneath the tank, tucked behind the headstock (presumably for protection) on both my 850's and on my 900 I have had intermittent faults which stopped when I reseated that bundle of plugs
