Just a wee update, to share my good news, and for info.
Got my dash back from electronics company, with a years warranty too.
Turns out it’s a very common problem with Fazers, as well as other makes and models. It was a small component inside which controls the power going into the dash, sorry I can’t remember the specific name.
He has fixed over 200 units for Fazers alone, disregard other makes.
So it’s now all back together and working like new again, and mileage etc all as it was when I sent it away.
It took just under two weeks from when I posted it, to when I got it back. They are very busy, which is a good sign.
Definitely worthwhile doing this if anyone has the same issue, even just to send it for testing, which is £25.
I am delighted that it’s all fixed, just wish I hadn’t spent so much time checking and cleaning connections etc, but hey ho, sh1t happens
£145 well spent I reckon.
