test the resistance between the + and - on each fan. it sounds like the fans are shorting out after being used for a period of time. i dont know the exact numbers but i know it should be very high resistance. like in the thousands of ohms.
i found this when googling how to test a 3 phase motor
To use a megger, connect to the line side of one of the motor leads with the red test lead. Connect the black lead to a ground on the motor frame. Depending on which type megger you are using, crank or press the test button. Most meters will read from left to right. Any reading less than 2 megohms is nearing insulation failure and should be seen too by a service center. Hope this helps, and thanks for using Allexperts, Charles.
you should be able to test it with just using the resistance setting on a multimeter. you are basically looking for HIGH resistance.
you could call flexalite to see what they say about the resistance of their fan motors. more than likely a service tech could spout off a number immediately off the top of his head. and they might even send you a new motor / fan if yours turns out bad.
goodluck. make sure your relay isnt shorted out aswell. that could cause fuses to pop. and look for imperfectios in the wire. it also helps to run the + wire away from grounds. aka just sheild the wire more than the stock shielding on it. you can accomplish this with some heatshrink  |
what kind of shitty advice is this? i dont think anyone with (good) basic electrical knowledge would recommend the above.
his fans work, i dont have a doubt in the fans being faulty. i would imagine that if a fan doesnt operate properly, it wont even spin loosely by hand, let alone when powered. no need for resistance checks, its all a big waste of time.
whats more important is that he configures a proper dual relay circuit using good quality, heavy gauge wiring. these are not puny altima fans, each fan uses ~15 amps of current.. thats a lot of juice for one fucking fan.
i wont comment on the ms paint wiring schematic because theres just too much room for error there. do the math, put your electrical schematic on paper and go from there. if you understand basic electrical you'll be fine, its pretty hard to fuck up.
and like russ has said in the past, use some good quality relays (bosch, hella, etc) stay away from no name shit. i dont have any experience with fan control module, so youre on your own there.. but i dont see it being anything difficult to implement.
