Hard to say where the fuse would be. Hiding it would make more sense. I would unhook the alarm until you have time to look things over.

Yes I have unhooked the alarm to see if that is the culprit

well what I thought was unhooking really wasnt, but now I know for sure it is, I took it to car toys this morning and they took the brain out of it and all components, so let'* see if she will start in the morning......

It has been starting ok for the last 2 days but today it is starting to take a while to start again like it is being drained again by something. If I let it sit for more then 2 days it will be dead again I know it. So Know I must look at the aftermarket DVD player as being the culprit. Because the alarm and dvd player were the 2 new things put in before this started to happen to the battery. I hate to lose my dvd player. But If I must I will go back to the stock radio.

if car starts fine when used frequently it very well could be the battery. How old is the battery?
I had the same problem many years ago with my 86 GT Mustang. I had the battery tested seemed fine.
Charge would keep going down when car sat. I said screw it and changed the battery problem solved.

Well it comes down to the leak in the trunk now, I think the amp is getting wet and ground is shorting out the battery. Any one have a good link to a trunk leak repair? I found a couple but no pics..I am new to car repair so this would be new to me but doesnt seem to hard to at least find out where it is leaking. OBTW the battery and alternator check out a ok. My spare tire is under 2 inches of water and my back seat under the battery has about 1 inch of water..not good...

Find the leak. Could be the antenna, trunk seal, hole in wheel well.
