SYNC Gauge How do they work??
Ok you read the title, How do they work.:grinser010:
I would think when I have both engines running the exact (or Close) RPM the needle would be in the middle. I always try to run them at the same RPM while crusing and just notice the gauge is no where close to the middle. |
i have also wondered. good question!
|
Anyone? I am guessing off the tach?
Come on there are plenty of people smarter than me out there:grinser010: |
i believe the impulse off the neg coil lead fires a coil inside the scope[ same as a tach} but in a sync. scope there is a coil for each engine. when the potential across each field is 0 the needle should be mid scale[needle straight up] as on engine spins faster/slower the field becomes stronger/weaker and one coil overpowers the otherand drives the indicating needle accordingly.

You know you are synced when your motors make kind of an occilation sound. You could have a bad tach or a bad sync guage if they seem to be off.
