remove master switch

No idea how to replace it, but it costs about $500 in parts. My dealer replaced mine, threw in the labor, they felt guilty about the amount of time it took to do minor body work, so it can't be to bad if they comp'd me. I did notice the battery drain much less after it was replaced and I could actually go a bit of time without the battery tender connected.

good luck,

Is it only the earth-switch ? Very easy to DIY imo !

 

Loosen battery both clamps befor you do anything !

Find them and loosen the two screws # 12 which hold the switch in place ... you cannot clean inside of it, if failing it should be easier just to get a new switch imo.

But maybe the contacts are corroded or simply loose ...

Tell us what you found and how you solved it please ... make photo's !

You will have to remove the panel behind the front trunk and beneath the front window to best get at it. You'll see the accelleration sensor there as well.

 

Class in session: So does the #9 cable go to the battery negative terminal and the other cable grounded to the body? That's the wiring for this switch? If it is then how can such a simple switch cost so much even by F car standards? Some of the best aftermarket cutoff switches cost less than $100 (I've got one on my old Porsche).

 

That's exactly the case.

It's actually a really nicely done cutoff switch. The crappy ones you find on ebay for $10 are bigger and more crude, not quite as small. Does that justify Ferrari pricing? No. But OTOH.. does anything in the car justify the markup?

 

AldousVoice just posted a good story about problems with this battery cut off switch and shows and autopsy of a failed one that had plenty of corrosion.

Thanks Curt.

Holy crap. I've just added another item to clean/re-furbish before puting her to bed for this winter. Nothing a wire brush and some tlc can't cure.

Thanks for the picture Phil

Voicey did a very good article on replacing the switch ....
Ferrari 360 & F430 Battery Isolator Switch | Aldous Voice

And if you do a bit Googling you can find a lot of battery isolation switches. Voicey shows one with a removable key. If I were doing it, I would not want the removable key version and there are many good ones available.

Here is one I think looks good and I have purchased items from Waytek before ... good outfit. The switch here is $50 and is rated at 250A. They also have ones that looks like the removable key version for $10. Sure as hell beats the cost that Ferrari wants for a simple switch.

That is a nice switch!

 

Thanks too Steve. That is indeed a nice switch

 

One feature of that switch is that it is a twist to close the switch and then you push the center button to turn off or open. It is not only a battery isolator switch, but also an emergency off switch.

I will say better than original!

 

It is a pita job. Honestly, wipers and cowel need to be removed, which makes it a lot easier for me. I completely removed mine and relocated it inside, and I also removed all the extra ground cables in the cowel area.
