The term "contactor" usually refers to the relay that carries the main
current supply to the starter. This is already built in to the starter
(solonoid). True, the contactor or solenoid takes a good bit of current to
actuate but a separate relay to handle this seems like unnecessary
complication when a *PROPER* switch will do the job. Just haven't heard a
compelling reason why this relay is necessary.

Tracy,
I believe Bob's reasoning is to isolate the battery from the starter
in the rare case of a stuck solenoid on the starter that would prevent the
starter from disengageing from the flywheel. As you know the battery is wired
directly to the starter with no means to remove battery power if wired as
in the automobile. Probably a remote chance of failure but possible.
