Aux. air regulator woes., Engine unit dead, replacement too! Options

[Air_Cooled_Nut]

The AAR is stuck open on my 2.0L. In fact, when I connect it to the power source it pops the fuel pump fuse (25A) (IMG:http://www.914world.com/bbs2/html/emoticons/mad.gif) I put a clamp on the hose so now I have to feather the throttle at stops until the engine is warmed up. Obviously, if I take the clamp off then the engine will idle really fast once op temp is reached.

I found a "spare" unit but it, too, is stuck open. Why can't they stick closed? (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) So, what is there to replace it? I tried the 914 on-line part stores no no avail. AA was a PITA to "flip" thru their on-line catalog (yeah...whatever) and I get bored and gave up looking thru it. The device looks exactly like the unit I had on my previous Type 3 automatic -- which served the same function and was powered by the coil. So I got to thinking, the other units out there, for cars like water-cooled VW engines, use a similar device, just a little more aerodynamic looking (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) Would one of those (less expensive) units work? Can someone point me to a place that does sell AAR's for our cars (not a "I think such-n-such sells them")? What have others done to fix or replace their failing units?

Thanks (IMG:http://www.914world.com/bbs2/html/emoticons/beer.gif)

Cool pics ! It would be great ot see a gallery of parts like this one, either dismembered or intact (for "What does the AAR look like?" type posts).


BTW, did you do a test of the AAR resistance ? My AAR was killing my engine b/c the wire to it was dry and cracked, and shorted to the engine. Kept blowing the fuse to the ECU. Finally tracked it down when the fuse didn't blow, and I saw an awesome display of sparks shooting out from down there. Currently, I don't have an AAR. We'll see if I bother with it when cooler temps set in...
