Default Voltage Regulator wire very hot

I had an issue withthe 2 year old battery on my '92 Sportster and replaced it (Yuasa sealed battery). Typical for Phoenix area, but after using the bike for a 1 hour ride the same day, I tried to start it the next day it wouldn't start. I tried it again after work and it started right up, no issues. I did a little investigating and it seems that the charging system is working OK (about 14vdc when at 3000rpm, regulator has good ground, etc.)but I noticed the wirerunning from the voltage regulator to the circuit breakeris very hot. Looks like it got hot enough to slightly melt the connector in the wire.It's obviouslynot drawing enough current to blow the 30A circuit breaker, but this still doesn't seem normal....

Anybody got any ideas?
