This is a job that every 360 owner should perform. It is an easy DIY task but if you are unsure of anything then please consult a professional!
Most Ferrari’s are very sensitive to changes in operating voltage – jump starting is known cause voltage spikes and can damage the ECU’s and the lights behind the instruments. Low battery voltage can cause CEL errors on start up and a weak battery causes the alternator to over run which at best will shorten its life and at worst could even start a fire!
In the words of master Ferrari technician Ed Blasi…
Driving a car that has been jump started has serious implications. Surface-charging your battery using your alternator shortens its life. The alternator going ten to the dozen trying to keep a power-hungry car running whilst charging a flat battery wrecks rectifiers and 360’s end up with damaged alternator feed wiring. Risk of damage is both real and common.
All of these problems can be almost be totally eliminated by fitting a battery tender. Note that a tender is not a charger, rather it maintains a healthy battery as opposed to charging a dead one. I use an Optimate but there are other brands out there, namely Accumate and CTek. I can recommend buying an Optimate or Accumate from this Ferrari specialist: Walkersport.
Fitting the tender can be as simple as clipping it directly to the battery using the crocodile clips provided. I advise hard wiring the tender in and also recommend that you do not go anywhere near the battery (behind the passenger footrest). Whilst you are fitting the tender there is a quick and easy mod to improve the range of the remote control fob. For some reason Ferrari placed the antenna behind a metal shield which means the fob needs to be close to the car to work!
Before starting work, please isolate the battery but turning the master switch off (inside the front boot). Remove the carpeted panel from behind the passenger seat (UK RHD cars). This is what you should see:
The antenna is conveniently placed behind the metal alarm module panel which acts as a shield. Here is a diagram showing the position of the aerial:
To get it out, undo the 4 bolts shown above to loosen the alarm module panel – don’t remove it. Then carefully tug out the antenna (it is glued in two places but will pull out):
And here it is fully extracted:
Now place the antenna pointing in the other direction under the carpet and do up the alarm panel:
Now you can wire up your optimate fly lead. Connect the terminals as shown below:
Finally, replace the carpeted cover leaving the fly lead neatly in the corner:
