Instrument cluster disconnect and test

Hello everyone, a supplemental topic from my last post. I want to do some electronics and circuitry continuity test. Is it safe to turn the vehicles battery on and have the key opened to brining electricity in with the instrument cluster disconnected? I am not going to have the engine running. Thank you

Be very careful not to create a ‘short’ & burn out any of those copper ‘tracks’ on the back of the instrument cluster!

Thanks Andy, much appreciate it
