If the voltage, easily tested at the battery, is within the normal range of 13.8 to 14.8 volts at any tested RPMs, then diode failure in the regulator/rectifier can be ruled out. Rather than a short circuit, it is more likely that there is a poor connection that sometimes becomes an open circuit. You may want to check every related connector by disconnecting and reconnecting.
In your first post, you mentioned a garage fire and some wiring damage. Has the wiring to the speedo been checked?
