voltage regulator circuit in 92 explorer

i've been having alternator charging problems in a 92 explorer sport.
now, with a new alternator, (and new battery), the only way i can get
a voltage meter to register any output voltage from the alternator is to disconnect the connector where the harness from the alternator goes into the main wiring harness near the battery and ecu.
i've taken the wiring harness out (the small one from the alternator to the main) and it checks out fine. i've also checked all the fuses near the ecu.
i've read in old posts that the voltage regulator circuit includes the battery light and ignition switch. i *do* know that my battery light doesn't work, so this would seem to fit into the equation.
my question is: what now? can i get under the dash and wire directly across the battery light? is it hard to get to the battery light to check the socket?
thanks.

Does the battery go dead while sitting? Is there something (like an aftermarket alarm) that's draining the battery, and sucking up all the alternator's output?

no, it doesn't die while sitting. there's no alarm system, or anything else like that.
the alternator puts out voltage fine, but the output is abruptly cut-off when i re-connect the connector mentioned above.
