Yamaha starter solenoid

That was my problem too Steve, but over time the problem got more frequent until it was say one in three or four attempts and then almost every time! It was then possible to trace the fault with a meter with a bit of patience. Throughout all of this the solenoid 'clicked' when energised even when it did not complete the 'start' circuit. The last thing you want is to be miles from home when it eventually decides it's had enough!

Yes, they are Hitachi and that is what I've got on mine.

It might be worth getting a replacement anyway, if it solves the problem then job done and if not you have a useful spare sitting on the shelf for when you need it.
