Polarity correct with battery hookup?
Horn blow loud and strong, as well as anything else on the chassis battery?
What happens with jumping the house batteries to it, either with the aux. dash switch or with jumper cables.
Is there 12vdc or better on the starter itself and can you hear the solenoid itself clicking?
I had this on our chevy here, while traveling and when in a TX parking lot for lunch. Pulled the starter right there and replaced it with one from auto zone and just up the street a ways. Tested it on the ground and found that it the motor would run, but not engage.
One does get lucky now and then and hopefully you will as well.
