I have purchase a used flats boat with trim tabs and only the left side is working. I have eliminated these variables:
1-Both control pad buttons will control the left side motor.
2-Unplugged the leads and switched them. Still no right side movement.
3-I took the top off of both cylinders then took the right side cylinder off and plugged it into the right and the motor would respond both up and down.
Could it be the computer board? Is there any way to test it?
Thanks for any input.
