Fan Resistor Connection Is Oxidised

Recommended Posts

Hey folks,

 

I've been having trouble with the fan blow in my TC so I bought a new resistor. While changing the resistor I found the connection appears to be oxidised and partly melted. Is there a way to replace a single connection without changing the entire wire loom? Any other advice or tips would be much appreciated. I've attached photos of the connector.

 

Thanks

That is one of the problems of an over engineered car.  Spade connectors fatigue and the connection gets hot.   What does the other side of the plug look like? Is there a  wire or does it plug directly into the resistor? 

If there is a wire it is easy, Separate the wire that hooks up to the  blue wire and connect directly with a larger spade connector.  If it plugs directly into the resistor then the plug is self will have to be modified to allow the replacement of the fatigued connector in the plug.

The plug actually still fits into the resistor without any trouble but I am still not getting any fan. How do I replace the connector?

I have had to do this on an old hot rod I built.  First you have to find a good connector the same as what is damaged.  That is probably the hard part. Junkyards can be a source. Then with an ice pick or paper clip pull out each of the individual terminals in the connector.  Then its a case of cleaning up the oxidation of the terminals/or replacing them and reinserting the terminals in the connector.  It is a big pain.  If the connector wasn't visible, I would have just spliced the wires from the salvaged connector.

There is a tool that slides into the back of the plug to unlock the connectors so you can slide them out . Then you can replace the fatigued spade connector and get a new plastic plug housing

once you have the connectors out of the plug go on line and you will find the same connector for sale.  Check the fuses , a lot of times when there is that much heat the fuse is running  hot and blows,

Thanks for all the information guys! I will have a go at this :)

This exact thing happened to my connector as well. I did buy a new resistor pack just to discover a molten connector. The resistors were good.

 

I refurbished the connector with some spare contacts and it remained working till I sold it.

I crushed part of a connector only CBR600RR motorcycle, bought a wiring harness and used the housing and one connector from it.  There are some suppliers who carry the connector blocks and terminal pieces but they are hard to identify and source.  It's not hard to back a terminal out, what is had is figuring out how to do it!  Patience is the key.

Thanks for all the support  guys! I was able to salvage a connector from a junk yard and then splice the wires together. It's not the prettiest fix but it's out of sight and everything is working again!
