Battery drain problem

[XAlliedYouthX]

So I picked up a 240 from a guy on here and it looks like it has a parasitic draw on the battery. I drove the car home and it was fine for a few days until the first battery died. I figured it was just an old battery so I replaced it with a red top and then a few days later that battery was dead aswell.

Today I went out to the 240 with my red top nice and charged to start yanking fuses to find out what was leeching off the battery, no luck though. I pulled every single fuse and relay in all 3 fuse panels but the test light still stayed on. I did noticed that 80% of the fuses were of higher value then they were supposed to be but that's another problem.

I read that pulling the fuses should do the trick so I can track down the problem but that lead me nowhere. Is there anything else that I check to find out what the problem is?
