Fluctiating speedo reading. Sensor postition?

[renmure]

I went to my first supercar meet in the Ultima this weekend (one really sensible guy wrote on Facebook that the 3 highlights for him were seeing the Ultima, the Ferrari F50 and the Bugatti Veryon Supersport so I was in good company)

Anyhow... I noticed on the run up and back that at times my speedo reading fluctuated wildly (not just when I was chasing the Bug), with the needle sometimes going full scale and others just seeming to randomly jump about. Other times it was fine.

I did change the nearside inner cv boot not long ago and may have accidentally moved the pick-up sensor for the speedo that is nearby.

How do I know where to move it back to or do I need to measure how far it needs to be from the ring on the shaft? Might it be anything else?

Thanks in advance,

Jim

Thanks all.

Well, the gap was fairly big so I have closed that up. I have also fiddled around with the spade connectors and hopefully the combination will help. Will test it next dry day

Yup. That's the one. I am sure I heard one of the organisers say there was 100+ cars. Breakfast was fab as well Certainly was a well organised event. I always have great intentions of going to these things more regularly but always dither about and end up doing something else.
