2006 civic intermittent power cut out when compressor kicks in

Hi guys, recently purchased a 2006 civic Viti-l for my son. Nice car, recently noticed an issue when aircon is on auto and the compressor kicks in power to the car cuts out for a Split second, lights, radio the works cut out, the car is about to stall then kicks back in. It isn't too long nor has the car totally shut down, it is about to though. I assume it has something to do with compressor as it only happens when air con is on. Any one got any thoughts or could point me in the right direction. Appreciate all help

Check your battery its probably on its last legs, but yeah when the compressor does kick in it drains the power big time.

old battery or altonater,get them tested by orto elec

I vote battery

Check ground connections as well.
