Identified my Blown Fuse Problem

[steamship]

One of the minor issues I've had since getting the A8 is that it was continuously blowing the fuse for all the interior lights. I also noticed that when this happened, I didn't get the indicator flash when locking or unlocking the car. The alarm horn didn't work either.

After scouring the forum, there was a comment about the batteries in the alarm horn causing corrosion, so with Saturday being a good day and me being reasonably okay, I set about trying to locate the alarm horn, and this is what I found:

Two of the pins heavily corroded and part of the plastic missing:

With this removed, I replaced the 10A fuse, and so far, everything is fine. If I'm up to it, a trip to the scrapyard tomorrow and hopefully I can pick up the alarm and maybe part of the loom.
