96 XJ w/ lots of mods. 4.0 auto trans.
Something is draining my battery.
A week a go, using a multimeter my battery read 12.9 volts. About 12 hours later it read 12.6 volts. Fast forward about a week, the battery is now reading 3.9 volts. Second battery this has happened to.
What's the best way to figure out wtf is causing this or at least narrow it down?
