I put a 31" LED light bar on a few weeks back. Since then the battery has drained twice. No lights were left on or anything. I have a relay inline and a push on/off switch inside. Could the relay be causing this?

I bet it's the relay. Is the drain happening overnight or as you're using it?

I pulled the plug after I put in a new battery and it drained while sitting for 8 hours.
It has not drained since then. So I am going to assume the relay is the issue at this point. ARGGGGGGGGGGGGGGG
