Bench testing a GM starter

Here's a good question for those electrical gods on this board... If you have a fully charged battery (12.76 volts), a questionable GM starter, a set of jumper cables, and a remote starter, can you tell if the starter is bad? I only ask because I'm trying to get my plowtruck to start, and it makes no effort to turn over. I tried the afformentioned action, jumped the solenoid, and the starters (4)would engage like a good one will. However, when I install it, none of the 4 that I tested would do anything but kick the gear out to the flywheel (using the remote starter--without it, nothing happens at all). Won't spin the engine over for anything. I can grab the bottom crank pulley and spin it over by hand, so it's not locked up. The headlights, also, will not dim when the key is turned, if that helps. I'm stumped here, and just need a nudge in the right direction.

Thanks in advance, Chet
