Charles,
If you try to remove the 4 warning lights, you will break the housings. The only thing these hide are holes in the dash faceplate.
Remove the steering wheel with the 6 countersunk screws and the horn button. The speedo is held in with 2 "L" shaped brackets
that go from the back of the speedo housing to the back of the faceplate. These brackets slide over two studs protruding from
the housing and are fastened with two little knurled thumbnuts. Simply unscrew the thumbnuts, slide the brackets off the studs,
unplug the wiring harness from the speedo and push or pull the speedo out of the faceplate, depending on if you are contorted
under the dash or sitting in the drivers seat.
If you need to send the speedo out for repair, the ONLY place I would send mine is : https://momamanufacturing.com/

But like Clyde said, most of the time it is the sender. We probably sell 20-30 per year.

That link I posted below also has the rebuild instructions for the sender, in case anyone wants to bookmark that. There are only like seven electronic components inside the version we had (2 resistors, 2 capacitors, 1 diode and 2 transistors). You could buy all of those for less than $10 at most electronic stores or on the web. If you can solder, you can save yourself $490 doing a total rebuild. Apparently getting the case crimp open to get to the board is the hardest part.
To answer Anthony?s question, we haven?t removed the speedo yet so I don?t know the board construction on that in-depth, but some photos from F-Chat made it look like a single board (no baby boards / connectors). But with older Ferraris you never know. Whatever was on-hand when the car was built was what went in.

Subject: Re: [Ferrari] 85 308 GTSi QV Speedo / Odo Problem
Perhaps my approach was too simplistic, but when I had this issue a long, long time ago (I am almost sure it was my Mondial, which would mean 1996/1997), I drove to Ferrari of Washington, jacked my car up, pulled the sender, checked resistance across the terminals, and then went inside and asked the parts guy to check resistance across a new sender. He refused to do it for me. I figured if the readings were significantly different I'd know for sure that the sender was the issue. We had a debate about this but he flat out refused and said I could either buy the sender or not, but he wouldn't help me in this way.
I finally just bought it, installed it, put the car back down, and drove away and it fixed the problem.

Just buy a new sensor
That?s the issue 99% of the time
When mine stopped working that was the problem

Hi gang! I?m helping a friend repair his 308. His speedometer and odometer have both quit. He?s dug through FChat and Facebook groups for diagnostic help. The original consensus seemed to be the sending unit would be bad. So this weekend, we removed the sending unit and tested it per this document:
http://www.dinoplex.org/instruments/vegliaspeedosensor/?fbclid=IwAR3C6CZSPeCCVjtFFamIV5ypy371p5Rkn6PZiP_qtv74nJBh5jH3KrVoZW8<https://na01.safelinks.protection.outlook.com/?url="">
His is the Type 2 sensor in the document. Per the testing procedure, the sensor is good. It reads a hair over 4V with no metal in front of it, and bringing metal in close proximity to the coil makes the voltage jump to 8V.
So now we?re on to what?s next. Some people have said the needle/shaft on the speedo itself binds up and may need lubrication. Some have said the speedo board itself is bad. So some questions for you 308 gurus:
1) Is there anything else we should look at?
2) What?s the easiest way to get the instrument cluster out of the dash? I?ve read that if you pull out the smaller warning lights that there are screws behind them that will release the cluster and you can draw it out from the front without removing the steering wheel. Any additional information from those that have been there/done that?
3) If the speedo requires repair, what?s the best course? I know Palo Alto still rebuilds them. But you can also buy boards from Ricambi and some other suppliers. Any recommendations/warnings/suggestions?
Thanks!

Also, make sure the wiring connector/plug is clean and not marinating in motor oil and dirt.
