hola,

been searching around a bit, and asking questions in other threads but after not finding my answer I thought it best to start a dedicated thread.

the other day after several weeks of trouble free driving my battery stopped charging. I figured it was likely the voltage regulator - so I got a new one aong with a new ground wire for the batt as the old one was trashed. when I pulled the voltage regulator on the car I noticed it was in really good shape - long brushes and pretty clean.

while I was under it I noticed what is pictured below. take note of the black plastic "box" attached to the back of the alt. and the crack....

two questions -

a) could this be the cause of my no charging blues?
b) and more importantly what the heck is it called?

I am hoping this is it. the battery looks new (only had the car a month) as does the alt.

appreciate the help!

Scott
