I have been working on getting this LT clip V1 to retrieve the keys off my liteon 74850. I think my cuts are good. the drive ejects fine with the clip placed on and runs games. with the clip off it won't eject at all using the CK3 lite that I have.the test button lites up red with the ck3 in normal mode(blue led) and shows green in Mode B(red led). Using my multimeter on 200 I get a flash of some numbers when testing the bottom trace cut but it quickly goes to 1. the top trace cuts have no response at all when testing.

Normally I have the bottom pins surrounded in electrical tape but I wanted to show he trace cuts.

Need help Please!

cuts are good, blue led on ck3 is mode b and red is normal (you should not be tinkering around with that) make sure the pins on the switch are making good contact with the traces. Apply a little pressure with your fingers if necessary.
