Reply to "MTH PS1 Bottom Board Keeps Blowing"

That is the battery circuit current limit resistor. Do you have the battery connected opposite with the wrong harness. PS-1 and PS-2 5V battery harness with molex plug are reverse wired. So using wrong harness can do that. You also can have a fault on the bottom board battery transistor or the 9V regulator going high voltage. G
