16v suddenly cranks slow, won't start

[roccit_53 at hotmail.com (C Boyko)]

I did the "Free the Electrons World Tour #2" on my 16V in the fall , 
thinking it would solve all that is wrong in the world (since another lister 
noted a crappy ground connection), heck, I even got a new bolt for the "PITA 
under the airbox" ground. Turn the key, and still nada. It turned out to be 
a wire strap on the starter, (field winding strap?) and a starter rebuild 
fixed it.
The guy who rebuilt it descibed it as "crispy" IIRC. Perhaps yours is 
getting frayed, and you can catch it before the toasty condition occurs. Oh, 
if you go there, the illustration in the Bentley may not match your starter 
terminal locations.
Cathy, feeling like the queen of the "no-start"
