July 1: So it begins. Don't worry, this is not in the correct legal jurisdiction!

AIR Solenoid Static Test: Notes

Measure the AIR solenoid for a resistance of 4.8-6.8 ohms across the B+ terminal 6 and the ground terminal 4 at the AIR check valve at an ambient temperature of approximately 20°C (68°F).

If the resistance is not within range, replace the AIR check valve assembly.
