This was one of a few faults I had to look at on an SS11 a few weeks back.
It was just bad connections on the back harness socket of the speedo.
Should be first easy check to remove facia/dash front veneer wood and expose instrument fittings then pull out speedo carefully as not much spare wiring. Remove the harness socket from the back and just put back on firmly.
Speedo worked fine after that. I like simple jobs/forums/images/RollsRoyceForums_2014/smilies/tango_face_devil.png
Hi regarding speedo no access to a ramp to check the gearbox feed so had to take the car to hr owen bentley potters bar nearest place to st albans they checked it and had to send away for repair nearly 3 weeks wait anyway all done so no speeding fines not sure i have enough time for repairs on this ss2 approx what the cost for fitting a new aerial labour charge if i purchase one cheers DickHi Dickie,
Ok here are some pictures
Picture 1 shows the screw thread aerial lead attachment on earlier Shadows like mine.
Picture 2 shows this fitting removed. It has to be unsoldered from the brass inner guide tube before the whole outer assembly can be slid off. To do this remove the upper and lower bolts and then gently slide up no more than one inch just to expose the soldered point. When unsoldered the whole outer parts can be slid off. Do not pull out too much as you can break the wire where it fits into the screwed backing and very difficult to repair this.
To further strip down for shaft replacement you will have to remove the little knob from the top which is threaded on.
Picture 3 is showing rubber cover removed from motor to access commutator and brushes.
Picture 4 is showing gearbox cover which is a push on interference fit and can be removed to clean and regrease gearing.
Picture 5 is showing one of my aftermarket aerials cost around £40 made by Sceptre. Note how it is the type with the up/down switch again for those radios that did not have the auto aerial feed. This type is a much easier electrical installation on a Shadow and allows for the original dash/facia switch to be used. Unfortunately they do not have the nice flush chrome fit on the front wing and stick up about half an inch.
Picture 6/7/8 shows the RR original replacement I was sold but note the difference on the aerial lead fitting as it does not have the screw type fitting. To use this type it would require a female mating part to be attached to the car lead or the replacement of that lead to the interior which would be quite a strip out job to do.
I don't need either of these two aerials so happy to let them go. I do have a few other types but all are radio operated automatic and special slim types for my Lotus Esprit as a very narrow space for fitting these.
hope this helps but as I said previously hardest part is removing wheelarch liners to get to the aerial
all the best
Hi Steve thanks for all the info.Hi,
Problem is with aerial you just cannot get originals so will depend on what type you go for and what you actual already have fitted for compatibility.
Wheel arch liner removal is not always easy and screw heads may be rusted so difficult again if paying hourly rate to a RR specialist garage.
It may be a cheaper option to find a local radio installation specialist and get a price of them to include an aerial.
If you were local I would gladly come and do it for you. I don't charge for any work/forums/images/RollsRoyceForums_2014/smilies/tango_face_devil.png just ask you give something to charity.
Keep your old one though I will buy it off you and pay postage.....is it just not going up and down or is it totally broken/bent on the shaft.
All the best
