Key Off Battery Drain

[LS3M6]

Hi, I'm having the same issue at the moment, did you find the problem in the end?

I just disconnect the negative terminal n re connect when I want to drive. Have no time or $ to fix it correctly!

Their are some good Utube videos about doing troubleshooting for where , or what is causing a " parasitic drain " on a battery. Try watching a few the idea of how to test for it will make sense.
It also has been discussed in many threads here already try a search.
The most basic method would be pulling a fuse one by one a see when your test light goes, or meter indicates no voltage. Then reference what that fuse feeds powers. That is your focus.
