Alt. guage discharging all the time???

Sounds like you own a multimeter, so why not try the simple things that 67Dart273 suggested (our patient electrical expert)? Measure across the 2 field terminals on the alternator, with the engine running. 0 V is a command from the Vreg "give no output current" and 12 V is "give full output current". The Vreg responds to the voltage it senses, which is from its blue lead to its case (gnd), so measure what it sees. It may have a bad ground or not getting ignition power, or its output signal (green) is not getting over to the alternator.
