Description
The dual engine synchronizer is designed to indicate
engine synchronization extremely accurately when the
speeds of the two engines are compared to each
other. Engine synchronization may be difficult at idle
speeds. For proper operation, both engines must be
of the same type, have the same number of cylinders,
and have similar ignitions.
