Cali t Yellow Tach

 

HI Matt,
My tach is also yellow and illuminates when it feels like sometimes its on from initial start up then turn the engine off then back on it will be unlit, its not a lose wire as it does not flicker or goff or on over a bump.
I asked my local Ferrari dealer to take a look and he said how deep are your pockets? He said it would probably be like looking for a needle in a haystack.
I have the solution and its a very direct cheap quick fix, i will whilst i refit my dashboard after my radio install retro fit a direct wired bulb (same type inserted into the holder) to the ignition switched wire on the hazard warning switch - probably a 30 minute job

Cheers

Andrew

 

Some of the coloured tachometers light up at night but not during the day. This is to preserve the legibility of the tach numbers in the daylight where the contrast of the black/red numbers is better against a pale background than if they were lit. Our yellow tach on the Cali and white tach on the FF behave this way.

 

I have the same issue. Did the battery tender trick solved the issue? Is this really a low battery problem?

Mine keep dark and sometimes it flicker a bit, and once after a few minute of flicker then the number light goes back on. It stay on after a week then it go blackout again. It remains flicker sometimes.

 

Did the dealer tell you what the problem was?

 

I changed the tach face plate on my 2013 Cali 30 about a month ago because I wanted a yellow one. I bought a (relatively) inexpensive instrument cluster module on eBay. It had been removed from a salvage car and had a terribly deteriorated (sticky) black surround. I disassembled it to remove the yellow face and found two illuminating rings (the pink ones) under the face plate, one for the center of the tach and a larger diameter one for the outer area. They are attached with stickem and can be carefully pried up and pressed back when finished. These rings are flexible and have two lead wires each which plug into the base unit. If either of those leads pop out of place that ring will go dark. It’s very delicate work but nothing I felt I couldn’t handle by being extremely careful. I kept a detailed list of step by step instructions as I went along. Here are the pictures...

While I had the top of the dash off I discovered that the leather was starting to detach in places around the edge so I reglued it down. The first picture shows the leather skirt under the instrument cluster that surrounds the steering column. The part I repaired is the upper dome.

Thanks for the details Bill, I just don’t have the guts to do it myself but with yours photos see if I can find some technician to fix the light ring for me. Great help

When replacing the instrument, was the milage odo meter showing the same value as before?

 

How exactly did you manage to unplug thesetwo connectors in the back of the instrument? Image Unavailable, Please Login

 

Sorry for the late reply, I just saw this post of yours. Yes, the mileage remained the same.

 

That rectangular thing on the top of each plug is a bayonet fitting, ie there is a ‘tongue’ which must be depressed while pulling on the plug housing in order to release the catch.

 

Could you press that tounge just with the finger or is a small tool needed i.e. a flat screw driver?

 

I don’t remember exactly, but it wasn’t difficult.

 

Ok, I tried a lot the other day with no success, therefor I thought it must be somkind of trick.

 

When you took the light disc connector out, could you loosen the disc pins in som way? I find them very tight fixed to the curcuit board Image Unavailable, Please Login Image Unavailable, Please Login
