         An interesting thought, lets run thru it.

>those contacts are good for a couple of hundred amps DC

         Generally a lot less.
         The relay does not control the starter.
         It switches 10A or so to control a _solenoid_
         (solenoid switch, actually) and THAT switches the 100s
         of A.


>(should do ok on AC as well).

         However there is an added question:
         What _voltage_ will the contacts see?
         I Assume 120vac or thereabouts.
         The automotive units are designed for 12vdc on
         the contacts (1k: more like 15vdc...)  This is
         About 8x UNDER spec for 120VAC control.

         What _voltage_ on the contacts?
