hi all
my speedo has never worked since ive owned the car and now that i have sorted out some other major things i am looking at what i need to do to fix it. I was trying to remove the cable off the back of the speedo and i cant figure out how it comes off. The book says to just remove the cable but doesn't explain how. I have been trying to avoid removing the dash panel so i have been reaching up under i thought it would unscrew or something but it does not seem to.

the car is a 76 without o/d and the cable is one piece from the tranny to the speedo, there is no egr counter or any thing.
I guessing its the cable because all the lights on the speedo work but the needle does not move at all and the odometer does not work either.

Dan,

There's a tab on the head of the cable that locks it onto the speedo head. There should be a lever that you can push in toward the cable to release the tab.

If you go to the TRF website and download the Electrical PDF file, you can see the lever on the cable on page 183. http://gar.zeni.net/trf/spitfire1500/pdfs/9-Spitfire1500-Electric.pdf

Your problem seems to be the cable. However, it also may be the gear in the tranny attached to the cable (small plastic gear),but not likely. In reference to removing the cable from the speedo, it may be easier to remove the dash panel as you may knock some wires off or loose from trying to remove it from behind. Better safe than sorry. It's not difficult to just take out the screws and just pull the dash panel forward enough to pop off the cable.

If that tab has broken off and they do then the cable won't seat and speedometer won't work. Sounds like you need a new cable

Dan, I hope it is the cable, and it probably is. My 80's speedo doesn't work either but its the gear in the transmission that is at fault for mine. My wife has learned to drive by the tach instead.

Yeah, most of the time and I do mean MOST the gauge is not at fault. It's usually the cable or like another person mentioned the gear in the transmission end. Oh, annd of course if you have the emissions "counter" those always seize up too.

Dan this may be the cable you need ,I looked it up on the Rimmers Cat. But why not phone them to confirm. I have spoke to them on before and they are helpful. Victor http://www.rimmerbros.co.uk/Item--i-GSD410

Hi there,

I also have a speedo bug since I installed an overdrive.
It just quit after 200 feet when I left the garage.

I bought the correct cable, installed it with that darn little plastic lever.....no place to work on the darn thing....chucked in an electric drill, reversed it and the speedo works....
I thought that I would have to open the tranny the check the nylon-plastic speedo drive.....nope....It is the angle speedo drive that is not transmitting the revolutions. The small gear inside does turn but the exit female hole is rounded off, the cable has a flatened spade that fits in it.
I received a new angle drive from England,through Ebay (I had ebay bucks so it cost me a whopping $10.00 !)and after trying it by putting a jeweler's screwdriver in the female portion and turning it by hand, it functions properly. The old one with the brass coupling, original, is a dodo.

You have to install a washer-adaptor spacer part number 3H 550 in the angle drive, without it there is an excessive end load and premature failure of the right angle pinion will result.

A US 79 should look like this is normal attire. If yours only has Km then someone has changed it based on it having the U in the Commission#.

I imagine your car, or at least the speedo came from Canada. We changed from miles to kilometres in the mid 70's.
