. 1.IC PA (POWER AMPLIFIER) IC PA (POWER AMPLIFIER)
To check the positive foot in PA we use multitester on X1 calibration, how:
Put the AVO red (+) cable in the positive battery connector (+) on the pcb board and the black (-) AVO cable on the negative battery (-) connector, the needle will move. Move the red cable to the negative battery connector, and the black wire on the battery positive connector, the needle will be silent (immobile). This indicates that the positive path of the battery to the IC PA is in good
condition, but if the analysis is not as above then the positive battery path to IC PA short (short) or broken.
2.IC POWER SUPPLY
Set calibration on X1, place the AVO black (-) cable on the positive connector of the PCB battery and the red cable (+) on the positive ELCO foot that is directly related to the inrush current to IC P S, the needle will move from the positive point of the battery to the IC PS either.
3.IC CHARGER
Set the calibration on DC10V, then connect the charger which is flowed by the power of the chager connector in the phone. Then turn the AVO red (+) cable on the battery and black (-) positive connectors on the battery negative connector, the needle will show the value corresponding to the existing tag on the battery, means IC CHARGER in good condition.
4.IC INTERFACE
Set calibration on X1, black wire (-) AVO latch on the battery positive connector, and red (+) cable on one of the lamps, the light will be lit means IC INTERFACE is in good condition.
5.VIBRATOR
Set calibration on X1 place the black wire (-) on the positive connector of the battery and the positive (+) cable on one of the vibrator feet, if jaru moves means the vibrator positive lane is in good condition.
6.BUZZER
Set calibration on X1, place the black wire (-) on the positive battery and positive (+) connectors on one leg of the buzzer, the needle will move and the buzzer will sound, meaning good buzzer path.
7. LED LAMPS
Set calibration on X1 place the black wire (-) on the positive battery connector, and the red (+) cable on one of the lamp legs, the illuminated lamp means the light path is in good condition.
8.ELCO
Set calibration on x1, place the black wire on (-) on the battery positive connector, and the red (+) cable on the positive ELCO foot that is directly connected to the battery positive, the moving needle means the path to the ELCO well.
9. HOW TO MEASURE BY USING MULTITESTER
A. When measurement of path / component we use calibration on OHM METER (x1, x10, x100, x1K) in currentless condition.
B. If DC Flow (battery) we must use calibration at DC Volt (10V, 50V, 100V, 250V) in current-fed condition.
10. MEASURING FUSE (SEKRING) MAY BE BROKEN
Set calibration on x1, place the red (+) wire on one of the legs R fuse, and black kabe on the other leg, the needle will move means the fuse is in good condition.

This indicates that the positive path of the battery to the IC PA is in good condition, but if the analysis is not as above then the positive battery path to IC PA short (short) or broken.

4.IC INTERFACE
Set calibration on X1, place the black cable (-) AVO on the battery positive connector, and the red (+) cable on one of the lamps, the light will turn on the IC INTERFACE in good condition.

Qo can be like the above yes Boss ???
for No-1
As far as Sy is concerned, in mobile phones there are generally nonpolar or polar capasitors connected to legs (+) & (-) connector batteries so that
