[V8] Battery discharge issue...

[William Gutierrez]

Thanks Mike and Ingo,

So, I have some more information to add to the story.

I hooked up the meter to the neg. of the battery to look for drain, then 
layed down on the passenger seat to access the fuse box.  When I did, the 
meter spiked up over 10 amps.  I'm guessing its something to do with the 
seat heater in the front passenger seat, but it seems strange that there 
would be any power to it with the keys not in the ignition.

In any event, using the one fuse at a time trick, I came to the #7 fuse, 
which when removed, caused the meter to drop from 1.5 amps to about .3.  
Seems like this is the culprit.  The fuse chart shows this to be for left 
tail, parking and sidemarker lights.  Any guesses as to why these would be 
drawing so heavily?  Is there perhaps a relay or something that is bad?  One 
additional thing to note--the fuse has a 15 amp installed, whereas the 
manual calls for only a 5 amp fuse.  I'm thinking that perhaps an 
aftermarket item was wired to this fuse, and someone upped the fuse to 
handle the load, but perhaps it was just someone inserting whatever they had 
on hand.  Perhaps the additional amperage on the fuse caused something 
downstream to burn out?

Anyways, any advice is greatly appreciated.
