Hey, I've just completed the crack and it is working, and decided to work on the speedball. I've completed the speedball and it is working up till the large board part. After mounting the large board, it fails on the resistance check on terminals OA, and OB. I've resoldered each and every joint and it still doesnt not give a proper resistance reading and I've triple checked everything to make sure everything is connected to the right place

What gives? Also, have not measured voltage readings because the manual explicitly states to not power the amp if resistance checks fail.

NOTE: the readings it gives out is always 1.

Read the manual for your meter.

Is this an autoranging meter or one with a range selector switch?

The Speedball manual does not have resistance measurements for the small board, but it does have voltage measurements. 

You should follow the steps in the "Small Board Voltage Check" on the bottom of page 18 and let us know what voltages you end up measuring.
