Keith, 

I would recommend connecting a 1N4004 diode across the positive an the ground 
terminals of the relay coil. Connect the cathode end of the diode to the 
positive terminal and the anode end (the end of the diode with the line om it) 
to the negative terminal. this will have no effect when the relay is energized. 
When a relay is denergized it generates a spark which can burn the points. The 
diode will allow this spark to travel through the diode and dissipate. 
Connect to relay negative connection. Connect to the relay positive terminal. 

Diodes should be across the terminals of all relays and solenoids.

I have a 62 TR4 with Trim Line electric fan, Derale fan controller, 30 amp 
fuse, and 30 amp NAPA relay. In the past 5 or 6 years, I have likely replaced 
the relay six or seven times. The wiring seems pretty straight forward and all 
seems in order. I really have no idea where to look next. Any suggestions?
