cooling fan wiring

[lindbergh]

Attached is some pics of the fan wiring done by the PO. Does anyone know what was being done or attempted. I don't know what the green device is, possibly a high amp fuse? With the OEM fans the wiring and green thing got so hot causing resistance to increase to the point of spinning the fans varying between 0-100 rpm, too slow to cool anything. With Toby's fans the fans stay on now and while the wiring still gets quite hot it does not get anywhere near as hot with the old fans. Note the melting on one of the connectors, this I believe occurred when the wiring was connected to the circuit breaker and this was the PO's fix. Thanks.

The wire jumper is the factory recall for the blue fan fail module. The green thing seem to be a circuit breaker.

The GREEN breaker appears to be undersized if color indicates anything it would represent a 30 amp breaker. This is your COOLING FAN breaker It should be upgraded to a 40 amp, preferably the stud type that would be installed next to the Fan breaker. It also looks as though your gold colored relays are OE. You might want to replace them. It also appears one terminal connected to the green breaker has been HOT based on the melted plastic terminal cover.

Don't use the cover for the fuse block. It makes the fuses get to hot.
