I am having an issue with a leak in the battery power, it stays active if i leave it running but if i leave it overnight the battery is completely dead when i wake up. It will not even attempt to start up there are no sounds no lights nothing. I never leave any lights on or anything. Where is the best spot to start testing for the issue?

Your alternator should carry the load, engine running. Maybe a faulty battery or connections. With everything turned off, if you have excessive battery drain, pull fuses one at a time, when you pull fuse on effected circuit, the excess drain goes away. It's best to check amp draw, but, there are other ways.
