well.....

after trying for a couple weeks I gave up and ordered another alt WITH A NUT. at some point during storage the threads on the Bosch alt got damaged. tried little files, a thread file, dremmel, etc to try to clean them up. I had lost the nut and it appeared to be a M16 x 1.5. I used my tap and die tool to measure the thread pitch.

when the M16 would not fit and it appeared to be too small I then suspected it may be an M18. finally got one and it is too big.

so got the new alt from Roger. no idea what it is but the nut on the new alt fit the old one fine. and I could not get an M16 on. so this must be some unusual size.

with the new alt on and the hatch closed so not interior lights on it only draws 48mA.

I just saw another post on the 911 forum where someone had the same experience with a bad alt creating a large draw.

if I had not noticed the alt light I would have spent a lot of time doing whach-a-mole on the fuse panel and never would have found it that way.

so another of the odd situations that can drive us crazy.
