Default fan connector burned up ( three pin )

what is the best way to repair this, if i just replace the male and female connector, it will probably just happen again!
i would rather find a more permanent fix.... thanks,

jerry

doing my TT kit install i just pulled apart the same connector and found the center female end burnt and melted as well. my fans are only set to 90% max.

im looking for something like this that can handle the amperage.

but for now im just going to turn back the fans to keep the car around 195 instead of 180 until i get a new plug.

At first I just took the middle wire out and bypassed the connector. That lasted about a year. Afte that I got rid of the connectors and put some big spade connectors on each wire and put heat shrink around each.

Carl, the connectors from Omega are not meant for any kind of high load application. Those connectors are meant to connect RTD and Thermocouple instruments to control systems. A RTD is nothing but a fancy resistor that changes resistance with temperature, no load at all. Plus its not sealed against the elements.

If you need a high load connection, I would suggest a Delphi Metri-pak series 280 connection. It is weather sealed and will handle 30amps. These connectors come in 1, 2, 3, 5 and 6 pin configurations. You can check them out here:

the fuse for the fans is rated at 60 amps, wouldn't you need a 60 amp connecter

Because at full speed the fan only draws 22 amps. Even with a DeWitts dual fan setup, they draw 27 amps at full speed.

just ordered the dual fan setup from dewitts, looks like the efficient design of the fan shroud will help cool and reduce the current drawn by the fans. that draw burnt out the connecter, next would be the harness itself

Im taking out my fan and shroud, going to do some fiberglass work to it so it seals better to the radiator, maybe add some vinyl as well. im just afraid that the fan has a side output and i dont want to block that off.

Is it possible to just cut the side that is burnt? Mine burned out on the right side. I'm thinking of just cutting it and connecting the 2 sidewith a butt connector

I did that very thing and it has been in operation over two years with no issues.

Cool! Thanks! Just wanted to see if anyone has done it. I didn't want it to cause a big short somewhere or something stupid.

My 100% stock 2007 fan plug melted. Never been tuned and still has factory demand on the fan. I just cut the connector off and used heatshrinked crimp connectors. Works just fine now.

I melted the connector to my cooled seats on my truck too, so GM doesn't seem to limit their borderline connectors to just Corvette's, for better or worse I guess

I'd say better, at least it shows their consistent in their undersized electrical connectors. Also, I'd base connectors and wire on start up load vs full speed load, but that's just me.

Yeah I'd bet they're just barely squeezing under the max amperage provided by the connector manufacturer. Throw in a few years of use, some corrosion, some heat from an engine bay, etc. for a few years and stuff starts melting

The connector burning up should have been your wake up call that your running the radator fan too much.

You go to a heaver type connector/do straight through soldering, and this moves the burn up point to either the PWM connector, or to the PWM itself.
