I'm trying to troubleshoot a problem on my TD electrical system. I have
consulted all the FAQ, several good emails, consulted the manuals and an old
Peterson's book on how they work (and considered sending the regulator off
to a pro). BUT I am confused about a few things.

I don't think my battery is charging and if I disconnect the battery the car
dies. When I flip on the headlamps, I get a -10 amp discharge.

The cutoff contact seems to be working and connecting to the bat at 12.5 or
so. The regulator side of the VR is what is confusing. I can adjust the
voltage at the D terminal to 15.5 (or whatever). But I not sure I getting
the proper amperage. I do have an adjustment that lets me tighten up the
contact points on the regulator side. I can watch the points arching so I
know they are opening and closing. I have set these at .020  Is this
correct? The manual pictures don't look like mine and everyone discusses the
cutoff and voltage levels. Any insight?

Thanks, Mike
