[QUOTE="acharris05, post: 716810, member: 65321"] Hi all, I got the PRAM battery and replaced and then I did the resetting of the PMU chip and the Imac is still the same. The only crackle sound I get seems to come from the coils on the mobo when I turn on at the mains. I got 3.63v on the battery I get -0.81v on the DCO board but I only get 1.31v on the 5v trickle voltage Am I right in assuming that the 5v trickle voltage should read around the 5v. Should I check the fuse to see if that it OK. Thanks. Anthony [/QUOTE]
