See these photos, and you will see two sets of two wires - two red, two black. The middle pin of the San Diego battery connector MUST NOT BE TOUCHED. The two reds near one end, and the two blacks near the other end, are shorted together internally in the phone, but again, DO NOT TOUCH THE MIDDLE PIN!

~~~ NOT FOR THOSE OF YOU WHO ARE UNSURE ABOUT ELECTRONICS, AS THIS COULD BE THE END OF YOUR SAN DIEGO, AND KILL IT MORE! ~~~
My friend said the San Diego had TOTALLY died and would not charge, so here's what I did, and it worked to revive the handset!
1/ Remove the back cover from the handset.
2/ Look at the above photos, and unplug the battery connector from the PCB - it lifts straight UPwards, very easily.
3/ Prise the battery out of the battery recess - it can be done with an old credit card - it's only held down with double-sided tape.
4/ Get an old Nokia/Ericsson/whatever brand phone charger which outputs 3.7 volts DC, and strip the wires to the bare copper strands, and then wrap each wire around a cork board pushpin or a dressmaking pin. Next, using a multimeter, check which of the wires is negative, using the DC voltage range.
Ensuring the battery is unplugged and TOTALLY clear from the handset, hold the pin or pushpin which is connected to the NEGATIVE wire of your modified phone charger, and press the point into either one of the two OUTER CONTACTS which are marked as "-" on the photos, and then grab the pushpin or pin which is connected to the POSITIVE pin of your modified charger, and make contact with EITHER of the red wires shown in the photo (marked as "+") for ONE SECOND, and repeat this at 30 second intervals, a further ten times or so.
Finally, plug the battery back into the PCB but DO NOT put the back on the phone just yet. Next, plug the San Diego into a charger AND LEAVE IT FOR HALF AN HOUR. You can push the power button at any point during the charging cycle, but DO NOT disconnect for at least half an hour.
After doing the above, my San Diego SPRANG into life, and now works, so I can now use it as an HD camera and YouTube watching device!
