If u can connect to the flasher without problems,than instaed of battery i use 9V battery direct to the phone + and - . Simple.
I never killed any alcatel db old with this method.
If u need external power supply to the CABLE then u need stabilistaor like 78l05. Or i managed to add external power supply to original alcatel cable with only 1 zenner diode 5.1
Thats all.
