Auxiliary Air Valve

  1. Remove auxiliary air valve connector and connect an ohmmeter to both terminals. Resistance should read approximately 33 ohms. If not, continue testing as follows:
  2. Remove auxiliary air valve from inlet manifold and immerse mounting plate in cold water, avoiding contact of terminals and by-pass channel with water.
  3. The movable plate should fully expose by-pass channel. Gradually heat water. As temperature increases, channel should become blocked. If valve does not respond as outlined, replace auxiliary air valve.
