My engine synchronizer gauge pointer is pegged to one side of gauge?
First, check all the connections to make sure they are clean and tight. Of the two main components of the synchronizer, the module (black 5″ disc) usually fails before the dash mounted gauge. It has all the electronics and is more susceptible to electronic abnormalities. If the dash gauge pegs to one side the fault is almost always the module. The module part number is located on the under side of the module.
