vcc main short? connect to power supply, does it go nuts and draw max current

3v0 nand short, does the amperage jack up when you hit power, also can just poke a few caps around NAND

next test tristar, whats the voltage at the battery fpc with no battery but charger connected classic failure will be a steady reading below 3v like .6v flat, bad tristar it should jump around to match main voltage while it looks for the battery
