360 MODENA Alarm siren removed

[yzr500]

After my 360 manual coupe alarm siren decided to chirp even though it was not switched on I inspected it to discover that it had been opened by the prevoius owner and had a non orginal battery soldered inside .This must have been successful as it had not given probelms over a 2 year period . My question is that on unpluging the siren box the car could be started and driven could this cause probelms with the electrial system ? Also the main agent stocks the replacement on the original part number but the well know stockist has this part under a revised part number which has been updated three times from the offical part number .

Replacing the battery is relatively common since the originals are soldered in which is a pretty dumb design. I think the siren is separate from the alarm, so apart from your alarm being useless I don't think it will cause any other ill effects.

For a replacement, give Tim @ Walkersport a call - he stocks them, and is likely to be cheaper than Ferrari. It's where I got my replacement.

Are these the same for the F1 variant too?
I only ask because you specified that you have the manual version... ;o)

I don't think F1's have sirens - nobody would bother trying to nick one.

I'd be surprised if it's a different part - the siren is different from the alarm itself I think, and just plugs in behind the membrane at the back of the "boot" - there is no obvious reason why it would differ.

Sorry Dave, I was just being daft. Of course there's no difference. It tickled me a little that the car was specified as 'manual'

was only giving the info as a manual ( ive no axe to grind on the F1 v,s manual debates ) as I was not sure they shared the same wiring circuits , the siren box inside has a printed board also the plug in loom has many pin wires which seems to be more that just a siren ? the remote fob operates the centre locking and the indo flashers would the dash check on start-up confuse the ECU,s ?
