Sorry if this is a repost for some, but I didn't see this come through...
I'm still stranded with a box of alternators and no charging... :-(

It's an '88 Westy, with 1.6TD transplant, otherwise stock, using a 90A
alernator, back half from the original Westy unit, and front half from a
rebuilt A2 Jetta unit. I suspect there must be an issue in the van wiring,
but not sure where to start looking.

Thanks!

Here's a photo of a Santorini single cab from our Greece trip in April:
(20th anniversary trip! :-) Glad we're not there now... so sad to see Athens
in turmoil.

We've had far too much going on at home to spend much time on the van...
after putting her away in January, I seem to have developed alternator
troubles when we finally got her out of the garage a few weeks ago. A new
battery is dead flat, and the alternator light stays on with engine running,
tach sits at 0 until rpms over ~2000, but voltage at battery and alternator
indicates no charge, just a bit over 12V.

I have lots of spare alternators, so I swapped a new back plate on, and get
same results except no tach at all (I think this was a bad back plate). I
checked connector at instrument panel - wiggled and alt light went out, but
still no charge. I've also tried several voltage regs with no change. Can
someone point me to a good guide for testing alternators, or other things to
check?

ps: It's a 1.6TD transplant, using a Bosch 90A alternator adapted to fit
mounting bracket.

Thanks
