Hall Sensor Location?

Hall sensor is inside the distributor, and since advance is vacuum 
operated (I think), the HS wires move with the plate, and they are the 
likely culprit. Distr. connections should be also checked. What you 
talking about is the signal amplifier, which when it dies, usually 
doesn't come back to life. It could be located behind the glove box.

I returned to the school parking lot, figuring I'd swap it for the one in the car.  Imagine my surprise when I went looking for it (as described in my Bentley) and it wasn't under the plastic shield covering the wiper motor/vent air intake!!  Where the hell did it go!!
>As a side, I towed the bugger home and pushed it into the garage.  After taking a few more voltage readings, I thought I check for spark again.  While I was turning the car over, a nice blue spark was showing and the car started!!  Evidently, whatever stranded me, righted itself.  I despise self correcting faults. I am leery about the Hall, and I am going to check it.  So, any ideas where it might be hiding?
