    I've just fitted a new Exide Premium battery to the 1987 Testarossa as shown. In the process discovered an unattached wire. Shockingly it's permanently live, showing 12.5V to the battery's 12.7V. Any ideas what it is for?

    Alarm? Radio amplifier? Espresso Machine? My '87 doesn't have any TR-related extra wires on the battery.

    Agree, can only be for something aftermarket. Looks like you actually have 3 extra wires (red, orange and black)? All you can do is trace it to see where it terminates. With that large a terminal in that location I'm not sure what it would hook to--most aftermarket components like stereo, cell phone (80's), radar detector(s), alarm, etc. would not typically be in the battery bay...let us know what you find.

    "Shockingly" 😜

    By "permanently live" do you mean that it is connected to another battery? If so, it sounds like an alarm.

    Cheers,

    Or some type of lojack. Part of getting a TR back to proper running is gutting 30 years of aftermarket add ons.

    Isolate the wire(s) until you find time to trace it ...

    Dank je veel, Mel. Indeed, that's what I've done. I wonder how long it's been bobbing about like that. It does seem that bodge jobs are just as common on pricey Ferraris as on lesser marks.

    Thanks to all the advice. I'll do some investigating when I can and report back. Curious myself...

    I've wound up with extra bags-o-wire as well. Yes - "interesting" wiring is common.
