Battery, Alarm related fault?

[Ash']

Hey,

Just brought my Black PH1 172 today. However the alarm seems to have a mind of its own, there also seems be a loud single tone noise sometimes maybe from the immobilizer? also my battery isn't charging. Could this all be related to a dodgey wire? or maybe a wire might be touching something it shouldn't? Im not one for car electrics so im not 100% sure

cheers!

How do you think it isn't charging?

Water in the alarm siren is very common and causes all sorts of weird faults, try unplugging the alarm module under the passenger airbag see if any of it stops.
