OK, here's a weird one. Sometimes the battery is drained, sometimes it's not. I replaced the battery and 2 days later it's completely flat.

I'm gonna start running down wiring with a clamp on amp meter for lack of a better idea. Anyone got a "check this first" for this?

Thanks. I'll check that out.

 

If its not the Power Arial you could Try Pulling fuses 1 at a time and then removing one battery lead..If the battery lead flashes strongly when you contact it with the battery the drain fault is still apparent. Once you have found the faulty circuit after removing the correct fuse the battery lead will not flash on contact..Ensure you have the car outdoors when trying this as some old batteries can leak a gas which in rare circumstances can ignite.
