458 Italia Electrical Faults

Low voltage in start up ..most likely due to the tender not being on ..and/or a battery that is on its way out

Have the battery checked /replaced and always keep a tender on

 

Order a Battery Load Tester from Amazon. They are $40ish and will tell you right away the status of your battery. It will work for all your cars and anything with a 12v battery.

I just used mine yesterday for my two boat battery’s.

 

Replace the battery. Happens all the time. Weak start and all the ECUs loose voltage as the car starts and it causes many errors.

 

battery. i get this a lot. most times you restart and they're gone

 

As an FYI.... we at Antigravity Batteries have a Lithium Battery that has built in Jump Starting and it WIRELESS, so if you do over-discharge your battery you can simply press the keyfob we provide with the battery and get the car starting and going again without having to mess with the battery or see it. Just press the keyfob and start the car and drive away to recharge the battery or put it on a charger to recharge it. I know this is a thread about chargers but just saying you won't need to recharge this battery to get the Car started if you in a dead battery emergency...

Its a lithium battery, saves about 35 lbs over the lead/acid battery, has about 2x to 3x the lifespan, and in the event your battery get over-discharged, for example to long of storage, leaving some electronics on, or a charger getting turned off.... it retains enough energy to get the car started and going again so you will never be stranded with a fully dead battery and unable to start your car.

Yes, they are more expensive than a Lead/Acid Battery, but they do offer a better value over the life of the product, but additionally they provide the ability to charge much faster than lead, offer much more power for easy starts and less voltage drop on starting so that the Car fires up quicker.

If you interested here in something like that you can check out this link and we have a video that does a bit of a deep dive into them. https://antigravitybatteries.com/products/starter-batteries/automotive/ag-h6-rs/

As an FYI, if you not aware of us, we've been around since 2010 doing Lithium Batteries, and we are also used in the Pagani Eutopias, and in the new Ford GTD Mustangs, as well as tons or Car/Trucks etc. and big in the Racing segment in all motorsport. So we are not new, but we are a newer sponsor on F-Chat.

Lastly we do have a Charger that is significantly more advanced and offer more features and faster charging that the CTEK Charger for the same cost and less in most cases. It has a digital screen, 10Amps of Charging, Chargers Lithium and Lead/Acid formats, has a built-in Voltage tester, Digital Screen to tell you exactly what is going on compared to the old-school LEDs.... so it might be of interest to some of you. We have the Mag Code Adapter for Ferraris as an accessory and are getting the 4-Pin type of Connector ready also.

I've been running anti-gravity batteries for 5 years. So far so good.

 

DO you make 16Volt stuff? We will be looking for something for our NHRA car soon.

 

Thanks for using our stuff! A few months back we joined on as a sponsor because we saw more and more F-Car people were getting in touch.... at the same time I also got a 296 so wanted to be part of the community.

 

We do make 16v Batteries, and as you noted they are for Racing only.... we have two models, one is in an H6 Automotive battery size, and another is a compact Motorcycle Battery size.... so it depends on the application, but these cover most drag cars. You can reach out to me at scott@ antigravitybatteries.com for more specific questions.

 

Hi all,

my 2014 italia is also sporadically coming up with these failures. In my case, its getting tripped when the car is stationary and slightly rolls back a little I think. The electrical bus which has brake sensors plugged in it is getting a glitch and this sends the whole bus array into this failure mode and stuck in wet mode until you re start engine. Ferrari like to use brand new expensive batteries which mainly avoids these issues, but its often a sensor. It can be steering, suspension ir more likely brakes...any thoughts from others who have resolved this ? My next step maybe new brake pads / wear sensors....as my battery is 6 month old Bosch battery. By the way these Bosch batteries are not as good as the brand name, I see the normal pre start voltage is only just about 12v, not great !

 

As an FYI, most all the batteries are made by about 6 companies...and the batteries are just rebranded for Bosche, Die Hard, or Walmart Platinum Plus. so if the CASE looks exactly the same that is one give away it just a rebranded model...

If you are saying your battery is at a resting voltage of 12v yes that is way to low. It should be resting at about 12.6-12.8 as a fully charged lead acid battery. But Ferraris do tend to have high parastic drain on them, and perhaps you have some other issue creating a slight load on the battery.... but it should be staying at 12.6. Are you by chance not keeping it on a charger so often? Is that the voltage after a drive? For example after a drive it should be in the 13.xx range for a little time... then settle back down to 12.6v roughly... but not 12v. Also are you reading the 12v fron the Instrument cluster or bedause you actually checked it. In any event that is way too low of voltage... if its actually just 12.0v. I bring this up beause we are in alot of modern cars, Porsche, Ferrari, and Lambos all tend to start throwing flags and having gremlins if the batteries charge is dropping even a little bit. They are all really sensative.

 

Thats a v good point. The first replacement Bosch battery i got in UK was used one (supposed to be new) sent back and got the current "new" one. I agree 12.5 v should be a minimum but yes in the mornings it is reading 12.0v on the cluster which shows it not fully charged. I have a "tracker" but don't think its draining that much current. Even coming off the charger it is rarely above 12v with engine off and a healthy 13.8 v with engine on. Sounds like the "new" battery may not have been v good. But then the issue happens with engine running too. Previously 2 years ago when i bought it the issue was there so they put new battery in was great for about a year.

 

You bring up a major point that is sometimes the battery you get off the shelf just isn't a good one, they have the dates of manufacture on them as a 4 digit code, but sometimes you just don't get a good one. What to you mean by Tracker? A battery monitor (tracker) or gps tracker? the GPS type can pull a bit but down to 12v overnight is quite a bit.

With the engine on and getting 13.8 is a fine indication your getting charged by the Alternator, but will not give you any real indication of the Battery itselfs charging and holding a charge well since its the altrernator is doing its thing.... then also even entering the car in the morning your going to have a load when you open the doors and the computer starts and the interior lighting goes on and such... so that might drop it a few tenths, but to 12 is dramatic. Also if you are not aware, if you have had any deep over-discharges on a Lead/Acid/AGM batteries they get damaged which effects the ability to hold a charge, and lowers the performance in overall capacity and current output. So not getting a big over-discharge is something you really want to try to prevent, and the Ferraris can have some big parasitic drains.... This is basic stuff you probably already know, but just sayin'.... Basically it stuff we are interacting with customers everyday about. You can also chase your parasitc draw with an ammeter inline on the negative cable to Negative battery post (and not starting the care).... there are video on Youtube how to do that... but with that being said sometime is simply a bad battery.

 

Dash shows 12.0 v in the morning pre start up after good drive the evening before. Too low for 6 month old Bosch ?

 

Appears to be, but keep in mind you might be reading that voltage under a load from the Cars system.... meaning interior light on because you opened the doors, computer engaged because your in the car.... so it might be resting a bit higher actually and that 12v is while under a load, not the batteries actual resting voltage.

So I don't want to make a comment with out true data.... but generally you should be seeing about 12.6v for a charged lead/acid battery especially if you drove it long enough to get a good charge into it... draining .6 tenths overnight is significant.... but again need good data. Also note sometimes people aren't driving thier Ferraris very long and if the battery is already over-discharge you not going to be getting a good charge into it in just 1 hour of driving. So a couple factors at play... and are you keeping it on a charger at all? You might want to because we seen so many Ferraris with very high parasitic drains on them.

 

By the way we make a pretty cool product that will tell you all the data from your batttery... meaning you can see how fast it drains after it is charged, see how you charging system is charging the when driving or when on the Charger, and see the voltage drop on your starts as well as do other stuff. Then it sends that data to your phone to review with an App via Bluetooth. So my point being is they type of device can tell you your cars actual voltage because it will track it when the cars system isn't loading it so you can see the voltage before you get in the car and know what it is actually at without a load....

You can see a video of what it does here... and I put some screen shot below so you can understand... Your voltage shows up as a graphic and show the date and time and you can see exactly what is happening when you drive, when the car sits and so on....there alot more to it than the image below but its a useful tool. IF you need that type of thing.

Please note that you will see in that image exactly what I'm talking about... the car is sitting at about 12.6v... but then I open the car door and the voltage drops... you can see that as the first voltage drop on that graph.... so that is what I mean on the Cars system showing a drop in voltage but it not the actual state of the battery, its because there is a load on the battery.
