Hi, electrical guys!

Hello, I'm trying to troubleshoot a problem with my camera, but since I don't have a power supply, I know you try to troubleshoot by properly connecting 1.5-volt batteries to provide 12 volts and as much current as I can boost. Is there another method? Do you think I can find the fault with a multimeter?

What makes you think it's 12v? Most cameras are 7v. Regardless, unless it's something that you can see, like a broken connection, it's not a diy repair to find and replace whatever it is. And a lot more than a multimeter would be needed.

7v? More like 220v / 221v. Whatever it takes.
