To help Bliss with his tail light/trailer relay problems, I went out and measured the voltage drop across my trailer relay (with the circuit operating, of course). My stock trailer relay was eating up 1.7volts with the battery source putting out 12.5volts. There are better relays than our "stock" ones. They are touted as "heavy duty" trailer relays. He's had problems before with his relay, too. Some of the guys in other forums report voltage drops of well over 2 volts for some of the relays.
