power problem

[nadz]

Hi wondering if anyone would be able to help me with the issue I\'m currently having. The battery voltage seems to be dropping between 13-13.5 yesterday the car cut out on me whilst driving could this be a battery fault or alternator or possibly wirring issue? I did have a problem before we\'re the car cut out and there was no lighting or anything called the aa he said suspected wirring but the car managed to turn on at that time. I also have a clifford alarm.

Do you have a multimeter dude?
Aftermarket alarm does drain the battery however it could be wiring issue. Easy way to check if the alternator is on it way out is start the car and get the multimeter connected. it should read 14.5v  if that the case ur alternator is good.
