laptop came in with 5v not upvolting. checked the cd3215c's and r3169 has a bit of corrsion. cleaned it off and now its upvolting to 20v drawing 1amp. put the logicboard back in housing and i get a chime, but as soon as it boots to ssd it resets. i can hold option boot and it stays on, but if i select ssd i get apple logo for 1-2 seconds and then it restarts.

im getting the following on the big coils
1.8v
.9v
2.5v on the 2.7v line. is this within tollarnce or is there an issue here? what else should i check?
