identifying positive on green board

[andrewknackert]

i apologize ahead of time if this is a re-post. I have not seen any images like my acer board on the forum. like most first timers i have made a simple mistake. I forgot to pay attention to which side was positive and which negative when i removed my bad caps. I have an acer al1916. I have identified the bad caps. I have included a crude paint drawing of the markings on the board. If anyone could help me tell which side is positive it would be greatly appreciated.

Re: identifying positive on green board

The general convention is that the solid part (the one filled with ink) is NEGATIVE so you align the - lead of capacitors to go in this part filled with ink.

There are exceptions though - some Asus motherboards for example use the filled part for positive. Other boards just put a + sign where the positive lead goes.

To be really sure, apply power and use a multimeter.

you should find other electrolitic caps on board they will be marked in the same convention if not able to find check on schematic.

do not apply power until you are sure!!!
