questions about modding a slim ps2

[sublime90]

that figures. i was just taking the laser and putting it in. i have a multimeter but have no idea how to use it lol i bought a 20 dollar one from radioshack and when ever i set it to ohms and put it on my laser it says -0 the OL every single time on every setting. another thing i was thinking is to mail the cd drive part of the ps2 to the place i bought the laser from have them adjust it/install it so when i receive it all i have to do it plug it to my ps2. the laser i have now i think is as good as dead i manually rotated the dvd screw on the laser very small turns but it never worked
