2007 ls 460
i changed the battery terminals then a week later the dash started blinking while driving (nav screen goes off and comes back on also).
When i park the battery is dead and i have to jump it off or charge battery. It may go for days but the same thing reoccurs.
There's a heavy current draw because the positive terminal gets too hot to touch.
Help...

 

If the last thing you did was to change the battery terminals and there is a short now, this is exactly where i would take a look at.

 

It may not be a short. If there is corrosion or oxidation, there could be a lot of resistance between the battery terminal and the terminal connector. I would try cleaning the battery terminal and connector and try reconnecting to start. A lot of resistance at the terminals can cause issues with the electronics of a car.

 

Dirty connector many times act like a diode.
