I searched the archives on this, but didn't see anything conclusive:

I now have this wonderful isolator that says if you have a Motorola
alternator with "auxiliary terminal" that you basically take the
output from that (without unhooking anything else), run it through
the isolator and into the aux. battery.

So, the question is: does the '87 alternator have an auxiliary
terminal?  I presume it's a Motorola.  If it does, which one is it?
The little screw on the left front that has nothing hooked up to it?
Bentley is not real clear on this either; they just tell you how to
take it apart.

Plan B is to bag all that stuff and use the alternator output like
everyone else seems to have done.

Thanks,
