Lo and behold, the starter solenoid rapid-clicked, just like a normal drained battery. I hooked up my booster pack and it fired right away.

My questions are: Should I look anything over since it was hooked up backwards? Does this model have some kind of reverse polarity failsafe?

It was straight batt to batt, hooked up for at least 3-5mins. Booster batt had 12.6V. Once started, alt was charging at 14.2V and the van seemed to run OK.
