Here's the setup
My port tach has been all over the place, several issues found and corrected. It got better but still varying alot. I was going to swap the wiring on the tachs and see if it followed to the other side to elimimate the source or tach as the issue. That's when I found the sync "hockey puck" under the helm. I unplugged it and it got better. Tried reversing the two plugs, all it did was disable the sync guage, centered but would not move. Both tachs were steadier though. Any information, schematics, drawings etc. around? I do have the boat wiring diagram but no info on the tachs/sync. TIA
