Speedometer works, odometer works and trip meter works, but I am unable to
reset trip meter to 0 miles. This is a 85 XJS. Anyone have this problem before?
Thanks

 

Yes. me for one. Nothing for it but to take the speedo out and open it up, find the problem and fix it. Which I was not brave enough to do...
This is a pretty common fault on them. For an extra 5 UKP per car, Jaguar could have had Rolls Royce quality instruments, they were offered the deal, but turned it down, this was in the 1970s.

I have an extra speedometer which I took a look at. For the life of me, I can't figure how the reset works. It looks simple enough. Just a stem the pushes on a set of gears and dis-engages them. Something has to tell the trip meter where the beginning is. That might be the trip computer? My trip computer has been removed. Otherwise, I just don't see it. I did find, on-line, a shop that repairs speedometers of older cars. www.bobsspeedometers.com
I may give him a call. I not sure if it is really worth the trouble. I can calculate the miles.

 

Assuming your car is a pre facelift, the speedo trip is purely mechanical and not influenced by the computer trip in any way. But hoe the trip gears actually work and are zeroed is beyond me too! Even when new the speedo trip reset never seems to work very convincingly.

I have never found out how to reset the trip meter.

Yesterday when reading Haynes just for fun, they mentioned a cable for this function near the inertia switch !!

My car is not near me now, so I have to ask:
Is that where to look for the trip meter reset button ? No wonder I haven't found it in the instrument cluster...

 

Don't forget Greg, Jaguar was under BL ownership then. That meant that every little penny they could save, and be it by using a worse rubber or a lower grade of plastic, was used. So £5 more/car is like for every penny scraping scrooge a full week's shopping!

 

Yes, this car has the HE engine. The trip computer was optional in some markets (Germany being one) and on some models. That console would looks as those it has been replaced (and not with the proper wood).

 

Wrong thread! Sorry.
