Traction control

["John Burk" <joyseydevil@comcast.net>]

A device called a synchronizer is available for twin screw boats that lights a
light when engines are not running close to the same rpm - If the inputs came
from the drive shaft and the hub of a nondriven wheel rather than two engines
the light would being indicating wheel slip - If the no wheel slip input from
the nonpowered hub was X% faster than the drive shaft the light would indicate
X% wheel slip - For diesel boat engines they make something to create a signal
to talk to the synchronizer so it can't be to hard for a drive shaft or a hub
to do the same - Synchronizers cost $200 to $300 - As its not closed loop
wouldn't think it would be prohibited - The original light might need a relay
to light an attention getter - Could some of you comment on the feasibility of
driving with something like this . John
