Hi guys,

Over the weekend, my el cheapo Chinese DSLR coupler for my Canon DSLR failed. Basically it would work and then stop working. Thinking that the connector to the battery casing was loose, and in an amateur effort to make it work out in the field, I stuck a small piece of aluminium foil in the plug hole which then made it fail completely!

Rather than get a new unit, would like to have a go at fixing this.

Was thinking that using a hot knife I could take the battery casing apart and simply cut the end of the plug off and solder the two wire ends to the inside of the battery casing. Would then cover the soldered ends with either silicone or some araldite, and glue the casing back together.

Have access to a soldering iron but have never soldered before.

The battery casing has clearly +ve and -ve marked ends that sit into the battery compartment.

Any advice on how to best do this? and how do I identify the +ve and -ve wire ends from the Power Adaptor to match what is inside the battery casing?

Need to make sure 100% that I don't fry my DSLR!

Thanks in advance.
