Electrical problems

We connected a new radio/CD player to the RV battery and the engine battery did not start after doing all this. We boosted it & it started right away.

Today, we did the same to connect an inverter to the 12V battery & the engine did not start. Had to boost again.

Both batteries are brand new.

If we just play the radio & put the lights on, the engine starts o.k. It's only when we are doing work with the RV battery (12V).
