Okay, so after my AC got switched over to R134 at the dealer, I drove it
home...and the alternator idiot light came on. Sigh. So I take a look at the
charge at the battery. Good power coming from the Alt. Short story version
--- After going through the Bentley's diagnosis tree, I have a ground short
to the idiot light causing it to light when it shouldn't. Everything else
seems find. Rev the engine and the light DOES get brighter (otherwise it is
at half dimness).

Anybody been through this before? Got any ideas where I should look for the
short? (I pull the instrument cluster and fuse box and checked both of those
already.)
