[s-cars] Urgent.. UrS4 vibrates when turbo should kick in...

Actually Joe, I believe Brian Powell has a rather interesting coil tester.
Perhaps he will chime in with his methodology (I think there is something of
an art to reading how far, or in the case of a not so good, unhealthy coil,
how not so far, a spark will jump.   From an email exchange with Bruce Mock
May 31 links .... 


When in doubt (if they are still in business ~ I think they've gone through
a couple of Chapter 11's) .... the old J C Whitney, .... or Army surplus :-)
or ...

although Brian's device was pretty trick in that it allowed the gap between
the contacts to be progressively lengthened so that one could build a
relative basis from coil to coil of spark/coil strength.  In fact it looks a
lot like the device in photo #2 at
