- This should be in a FAQ list. The A3000 power supply has a nice feature where
- it will not turn on if there is too low a resistance between the outputs and
- ground, i.e. if there is a short circuit. This saves you having to replace
- your power supply when you keep plugging in cables while the machine is on.
-
- Your spark caused a short to ground. You need to check where it is.
