So, I have been having what I thought was the problem of a stuck-open AAR.
1. Start car cold 2. Car idles at 1800 RPM during warm-up 3. Car gets warmed up and now starts idling at 3,000 RPM 4. Pull input to AAR and you can feel it is still sucking air in (a ton). 5. Plug the input to AAR and idle drops to 950 RPM. Today, I replaced the AAR (thanks fellow 914world member) with another one. However, the problem/symptom persists just as above. So now I suspect I am not getting power to the AAR so that its little bimetallic strip can be heated up. Where does the power wire for the AAR trace back to in the car (74 2.0L)? How can I test that wire? |

The AAR I sent you was tested.
I am positive it is working. Testing is simple. I applied 12 Volts and the it fully closes in about 5 minutes. |

I won't get time to work on it until this weekend. Where did you apply the 12 volts? It didn't have a spade connector on it and the sheath was not trimmed back on the wire. |

The wire goes to positive 12 colt and you have use another wire to ground if from the metal shell. you can attach it to the holes for the screws. |
