Evening all,

I'm hoping for some advice on a "simple" wiring issue i've got, and oddly whilst youtube normally helps my diy exploits it appears full of American videos for this one.

So.. i've got a fan circuit controller with a dodgy connector block. Here's the circuit:



And here's the connector which as you can see in the top right it's started to overheat and burn out.


After cleaning up both the female and male pins, the connector is still unstable so I need to fit it properly.

I managed to locate a new connector which is this one: http://www.ebay.co.uk/itm/TST06PA00-Itt-Cannon-Plu...
however my knowledge of wiring and connector blocks is pretty minimal. So how should I go about replacing the connector? I assume it's a case of cutting the cables, finding new female pins and crimping these onto the bare wires, and the new connector block should accept these just push fitted in?

Any advice welcome!

That looks like a conventional type of plug where the terminals are simply pushed into the housing and have an integral latch to prevent them backing out, typically just a simple tab formed into the terminal. If you inspect the open end you may be able to see the tab. It isn't always easy to access them, but often you can insert a thin tool between the housing and the terminal to hold the latch back so that you can withdraw the terminal.

If you need to replace the terminals and housing it would follow the process that you described, but note that if the connector you show here has been damaged by heat/corrosion, the connector it mates with has probably got similar damage. In that case replacing just one side may not resolve the problem.

Assuing this is the same as the ones on my last BMW, you can remove those pins as follows:

Normal drink straw (children's party one will do)
Cut a small slit in one end (5mm or so) so you can adjust the diameter of the end
Push the straw over the pin (at the end showing in your pic) and wiggle around while pulling the wire at the other end
The pin should release fairly easily

You'll see the pins have a small locking tab, which pushing the straw over will release it.

If that's not what you're looking to do I apologise....

Thanks All!

Sounds like a little trip to McD's for a straw is in order and i'll get some new female connectors to refit smile

Just an update on this as I hate it when the OP disappears..

All sorted now.. the new connector housing still had the same issue, so I ended up slightly crimping the new female sockets before putting them in the block, and the whole thing is now good to go, and no cutting out.

Phew!
