87 5000CS Avant battery cable splice

[Stephen Sherman]

Think I found the problem (as opposed, hopefully, to a problem).  
Alternator rear bearing is loose, has about 1mm or more sideways play in 
it (as measured at the pulley, by putting diagnal force on the 
pulley/shaft).

So my diagnosis goes that that bearing play was causing intermittent 
drop out of the alternator. Thus the dimming lights every so often, the 
way undercharged battery a few days ago and the random belt screeches . 
In any case, I think this will need to be solved first and I can see if 
that clears up the symptoms or not.

If anyone can see a flaw in this please let me know (hopefully before I 
get the new alt).
