ive checked double checked and tripe checked grounds.
motor is grounded by motor plate as well as ground from each head. big wire gounds not small gauge.
im leaning heavily on it being pinned wrong in the harness. just havent gotten the wiring schematic to find out for certain.
I’m not sure grounding through the motor plate is very effective. I ran cable from the battery directly to the block even though I have a motor plate as well. No issues.
