well, i've had my troyer fans for about 2 months now, and they've been great... till the other day when i noticed that the fans still ran well after the ignition had been turned off. well it stopped, i do alot of highway driving so never really noticed a temperature increase... i did notice that when stopped that the a/c would cycle on and off. and that when i turned on the a/c, my high side fan would not turn on, i checked my connections, to realize that BOTH of them are completly melted under the relay, and the relay's are thrashed?????? this sucks.....

 

Without seeing how the install was done, you need to be sure all connections especially any push-on are the best available and all type connection have zero resistance.
Reason is if there is any substantial resistance at the connection, it runs hot.
A hot running connection corrodes and make it worse yet until the connection runs so hot it's temp get to the melting point of the surrounding material.

Example this; a connection with a resistance of 1 ohm trying to pass fan currents of say 30 amps will be equivelent to 900 watts at an area that will never handle this power/temp for very long. How the example is figured is with electrical law of current squared, divided by the resistance or (30 x 30) / 1 = 900 watts of power when is should be less than about 5 or 10 at most.
This is what makes anything melt that normally does not run hot.

 

i used only the stuff troyer sent me, they gave me a whole box full of goodies...
