Hi guys,
But I've been watching the online Electronic Repair School on YouTube. When dealing with a motherboard that has a short, he injects 1-3 amps of current in to the board, to heat up the failing component (which carries most of the current) and then he touches the board so as to find out which component is failing. I've read about this technique many times before.

I want to use this trick on a few boards that I have here to try to identify the failing component, but I don't have a desk power supply. Has anybody done something like this with a battery? I could just set up a battery with a high wattage, low resistance resistor to do the same surely?
