X9 Owners & Riders Club

So my beloved Xevo 400 is coming up on 50tkm - its been great - but last week I noticed that the dash is behaving a bit erratically with the speed and rev counter dials bouncing around a bit - and the low oil pressure light occassionally coming on for a couple of seconds. I checked the oil level - all fine of course but this morning the MOT invitation letter came from the local Swiss authorities. Im guessing its a little bit of water in the fuses or at the contacts for the digidash but it's been so long since I've heard from anyone here I thought I'd see what the clever forum people think.
Thanks as always ,
Rob

Hi Rob,
It does sound like a connection issue to me as well, could be water, corrosion or just loose. Give them all a good clean, including any earthing cables, and hopefully it will solve your issues.

Thanks a lot Bob - will get to it and report back. Hope all well with you and yours.

Would it affect the MOT, it probably wouldn't in the UK as long as they can read the odometer. Probably just a dry connection.

Sadly yes - they're very particular in dear old Switzerland - I read in the workshop manual that it wasn't the oil pressure light that came on for a bit but the "Engine control telltale light and injection system failure warning light" - this light normally comes on for a couple of seconds after I turn the ignition key to on but I wait for it to go out before I press the starter button. I also read on a vespa forum that it might be the voltage regulator on the way out.

Think I have it sorted - corrosion on one of the battery terminals - 70 mile ride coming on Thursday will tell. thank you all!

Good, battery connection can create problems. You were also right in that regulator failure resulting in over-voltage can also have similar effects.
In the early days of the X9 regulator failure was a common problem but seems to have been much less of an issue since on newer models.

Thanks a lot guys - no further issues reported after battery terminal issue dealt with.
