Having said that, Tuesday the car set out in the sun for quite a while at the mechanic's shop, so the A/C ran at full-tilt for at least 20 minutes cooling the car down (inside temp at asipirator was 118 when I started the car). I didn't notice the smell this time. It may be that the resin is "gassing off" a bit, and assuming I don't ruin the regulator before the new motor comes in from FastLane, I'm just going to keep using it.
That's the best way to measure the current . . I have a Fluke and it works well but the accuracy of it (and yours) I suspect is +/- 5% or worse. When I measured my it was more like 26 amps or so.

If the blower was on HIGH, there's very little power dissipation in the regulator. So maybe that's why you didn't smell anything.
