[Vwdiesel] TDI altenator

[James Hansen]

I'm assuming you checked stuff, like the output voltage with your VOM 
(vom'ing in the rain...) and verified that the light is telling the 
truth..., that there is excitation voltage at the light wire and stuff.

I second the cd manual blows chunks compared to the paper manual.
Have you upgraded to the new bentley software Val?  It is much better 
than the old explorer window based system, which sucked at the very best 
of times. New one is a free upgrade, it isn't half as bad as the old 
stuff, but an old school analog paper book is still the far far better 
manual. (I have the cd for the Passat)

If you're sure it's the reg, not wires, just change the reg in situ.  It 
isn't a big deal to pull the alt really, just wires off, belt off, bolts 
out, alt out, assembly is reverse of disassembly.  The serpentine belt 
is kind of nice when you've had the opportunity to fight with the 
tensioner on a A2 with A/C.
