For capacitance tests, always best to test off the PCB if possible, though you can be lucky on the board. Use the capacitor test on your multimeter if you have one, and if you get the expected reading in nano-farads or micro-farads, then all well and good. | For capacitance tests, always best to test off the PCB if possible, though you can be lucky on the board.

- | For ceramic caps on the board, sometimes I like to test these using a continuity test. Placing the probes at either end, there will be a short beep at the cap charges, and will stop when it reaches capacity. Swap the leads around and it will beep again until it reaches capacity. | + | For ceramic caps on the board, sometimes I like to test these using a continuity test.

If you get an unexpected readings for any cap, remove from the board and try again after discharging it. | If you get an unexpected readings for any cap, remove from the board and try again after discharging it. |
