Ok, I got a '67 bug and my generator light came on. Both the generator
and regulator were new (the whole car was restored from the ground
up...just got it out the shop 3-months ago...and although both gen &
reg were built new (not rebuilt) by BOSCH, they were built in Mexico,
so...

Anyway, I checked the generator max voltage (ground the DF, disconnect
the D+ and measure the voltage from that to ground) and got .4V to .
8V, so it looks like the generator is gone. Funny thing is, ever since
I got the car out the shop, the reading on my voltmeter (VDO) has been
up and down -- pegging out at 16V on the highway, but dropping to 11V
at idle...down in the red. Just before it died it was down to 10V at
idle (minumum for this gauge is 8V). So I think the regulator burned
out the generator. I guess I should have paid more attention to it,
but I'm still getting use to the quarks of this bug (I had a '68 for
23-years, but that's another story).

So I ordered a new gen & reg, but I'm wondering if there is anything
that could have caused the regulator to malfunction? I'm thinking this
thing is like a fuse: it shouldn't just blow for no reason, right? But
then again, it is made in Mexico, and it uses solid state parts and
you can't crack this thing open and look for burns like the old ones.

Assuming the new stuff I get is good, should I worry about anything?
Something outside the generator-regulator system that could damage
either?
