if the alarm was installed " properly" and i use that term loosely, it should in no way affect your turn signals, i have my alarm unplugged at the moment and all lights work and function fine, is gotta be a wire grounding out somewhere or your flasher most likely, another thing you can try is take out each signal bulb one at a time and test, example: take out the front drivers side bulb, turn on the signals, see if they work, do this for all your signal bulbs one by one and if you pull one and they work, then you know its a problem with that bulb or wire
