need new ECM.....ECM ground failure
 Sometimes charges, sometimes not.  Possible cause ?

Worn brushes.
Bad regulator.
Loose connections.
Bad ignition switch.

 First, turn off the MIME - Usenet News is a plain-text medium.

 The first thing you check on an alternator that is starting to go
intermittent is worn slip-ring brushes.  If you can't get the field
current to the rotor, you won't get any output power.

 If you are handy, you can replace them yourself.  A set of brushes
will cost you under $10 at any good parts counter, a bit more if you
get the whole holder with the brushes pre-assembled.  

 Or spend about $75 and take the unit in to a good local auto
electric rebuilding shop.  They will change the brushes on your old
alternator, clean it out, lube or change the bearings as needed, and
check for other problems like bad diodes or windings.
