Only the 68-9 FI systems have a microswitch built into the TVS. This one makes a click when moving in and out of the idle position. This 68-9 switch has a 2- pin connector. Does your TVS also click with the key OFF? [The 68-9 switch will click with the key either ON or OFF.] Is there also a sensor hanging from the underside of the right side intake air runners? The 70-3 switches (which is what I think you should have) have 4 or 5 pins and are just sliding contacts. There's nothing inside that can make a sound. If your TVS click goes away when you turn the key OFF then you're probably hearing a sound from somewhere else, rather than from the TVS. Is there some chance that you have the early switch? Maybe someone has cobbled together a mosaic FI system and that may be part of your problem. > > Hmmm..., I'm not sure that you should get injector clicks when jumpering > > between trigger point pins, > > I do the jumpring with ign. on. Right, I assumed that, otherwise everything's dead.

I have them for $50 in good used condition. I agree that $750 is absurd, but the fact that your late TVS "clicks" bothers me, because it means that there's something wrong with this picture. We need to figure out what it is before we start throwing parts at it. -- Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
