[Vwdiesel] 89 Jetta D phantom voltage RESPONSES

[Doyt W. Echelberger]

That was a HUGE amount of help, guys. I appreciate the detail and the 
suggested tests. It will take me a few days to try the suggested tests. But 
as you say, the fingers all point to the alternator. I have a few spare 
ones from earlier Jettas that have gone to the bone yard, and if necessary, 
I can buy a rebuild.

James, thanks for the details on the blue wire and the diode tests and how 
the alternator should hit 13.8 right away. That is 99 percent convincing 
that the solution is to R&R the alternator, and I can get busy making that 
happen.

I'm leaving the Jetta at home until it is healthy again, and driving the 
Benz out of town for Memorial Weekend activities. Thanks again for being 
there with the virtual roadside help.
