The trim and rpm guages were working great and then they just seemed to lock up. The trim guage stayed in the middle even while the motor was trimmed up and down and the rpm guage stayed at 1 even as I increased and decreased speed. I have a 90 hp Evinrude and a Sunbird Corsair. My question is it electrical and if so is it related to the ground? Your thoughts and advice would be greatly appreciated. Thanks.
