Fan wiring issues

[Bellecobra]

Has anyone had issues with the wiring for their fan shorting out, but not blowing the fuse. Have had issues with my fan circuit. It seems to have had too much power running thru it and has melted the connector right where that section of wires goes to the main dash and wires. Took it out of the connector and put it by itself with a new waterproof connector. Has been working fine and not issues so far, just curious if anyone else has had this issue. Have it set up so the fan is on once the ignition is keyed so it runs continuously. Do find if I am driving and it is off engine has no issue staying cool it’s just at stops where if there is no fan the engine does heat up . Thanks for listening and if anyone has any place I should look for another issue, could have just been that connection.

Yes, I had this happen to me but in my case the impacted area was where the fan fuse was located within the fuse block.
The fuse did not blow but the fuse block was damaged because of the heat so I pulled the fuse and ditched that circuit.
My solution was to run a separate 10 gauge wire (Fused & Manually Switch) from my battery switch to my fan.

The melted "plug" is a sign of a bad connection and/or getting too much electrical heat. Hope you have it wired via a relay.

This is how it is wired.

I think you fixed it but...I wouldn't wire it that way. The problem as I see it is that rad fans draw a ton of amps right at startup. That is exactly when your starter is also drawing a ton of amps. So the overall voltage drops a bit and the fan draws a few more amps. Whichever connector along the line that has the worst connection may get hot. A note from my experience on another car where I installed an add-on fan. It was sold as a 30 amp fan. The suggested wiring kit was sold as a 30 amp kit. But it kept blowing the 30amp fuse. I went up a size on the wire and went to a 40amp fuse and that solved the problem.

The connection in question is in the RF harness, the pin for the fan wire(blue) inside the connector from the main harness to the front harness.
