Hello guys,
I had the brilliant idea to make a battery pck for my sony pc330.I end up fried something inside the camera.
I attached the battery pack to the camcorder and the batterie became suddenly hot, and then I smell a little burn inside the camcorder around the are of the power jack.
Then I tried to turn on my camcorder usint the power cord and/or the original battery , but no sign of life is coming from the camcorder.
the screen is black and no sound is emitted by the camcorder.

I am thinking that I fried something in the circuit that brings the power to the other components of the camcorder.

Is there any way to use a tester (I do not know if it is called like that) to test if the power is flowing through the different components ?

For the term tester , I mean a little instrument that has 2 metal points (+ and -) that I can attach to the + and - parts of the circuits into the camera and using the switch I can set the voltage or amperage and check if the power is passing through it.

Do u have any tutorial in how to use a tester ?

If I make a mistake in using the tester (not attaching the + and - in the correct points), can I frie somethig ?
Than kyou


for the people that are more courious and willing to help me more,
you can download the service manual for the pc330 here:

I think that I fried one of these two parts :

1) BT-021 BATTERY (SECONDARY) BT9901 (Lithium battery) BT-021

I do not know what is for this battery secondary . Do u guys know what is its use ?


Thank you
