I ran the 12v 5 minutes test on my aar. After the 5 minutes, it closes but still allow very small amount of air to go by. Is that normal ?

PB blaster plus compressed air, add 12 volts for about 10-minues, AAR should close off while the voltage is applied. The AAR will also get to about 130 degrees (used the HarborFreight infra-red thermometer) let it cool down either in the freezer or workbench, then reapply PB blaster and compressed air, repeat the cycle until the AAR consistently closes using a stopwatch. Yes, I did directly blow into the AAR using clear vinyl tubing. My AAR has always closed off to the point no air passes.
