There is problem with doing this sort of thing though - its called safety
The PDA will contain regulation circuitry to prevent the battery from going over temp and taken too far they can in fact catch fire with quite explosive results - I would try and get the 168 repaired or replaced than risk a battery fire through incorrect charging - the extra wires are often temperate sensors to prevent the battery from going up.
Try looking at YouTube and do a search for LiPol and it will show you what I mean, This is one such example - after one and half minutes imagine that in the house!!!! - Mike |

There's a post here somewhere where it tells you where you can get the part, quite cheap, and how to fit it, evidently no soldering required. I can't find the post at the moment but will have another look.

I've found it, I thought it was on this site but it was elsewhere.
| Quote: | For those of you who suffer the dreaded charge socket failure there is some news for you!
When mine broke I thought I was going to have to pay around £45 to get it repaired - not the case at all. Despite the online adverts stating it's a 22 pin connector (which is true) NONE of those pins are actually soldered at all!
Just 4 crosshead screws and split the case apart and you wil see the socket at the bottom of the motherboard. You will probably have to disconnect the gps aerial but thats just a small connector - don't forget to re-connect before you put it all back together!
The socket is connected to the motherboard by 2 small lugs which are actually part of the casing of the socket. Using a small soldering iron and a small bit of pressure, the socket will come away from the motherboard quite easily. I got my replacement socket on Ebay - around £4.50 inc postage!
Suggest you clean up the 2 places where the case goes on the motherboard to get the old solder out then just put the new socket in - you'll see that the 22 pins actually only 'pressure' connect. Make sure you press the new socket down as you solder the 2 lugs and hey presto a fixed 168 ! |
