Is this a single wire or two wire alternator?
Do we need to dump the diode type isolator and go to a combiner?

I think Ron was concerned about loosing the remote sensing feature of the OEM style alternator. If the replacement alternator is NOT remote sensing won't the isolator drop some voltage causing the charge on the batteries to be a bit low? IE: Combining a lower than optimum charge voltage doesn't really help!

You are correct. Using a one wire alternator (No remote sensing) with an isolator will cause the charging voltage to .7 or more volts low. You could charge a battery at that voltage but it might take weeks to fully charge.
If you are going to use a one wire alternator, I strongly suggest that a combiner of a bridging relay are your only solutions in a multi-battery installation. Also when using a one wire alternator there is no provision to make up for other losses in the system like in the fusible link and other wiring.
I would stay with an alternator that has remote sensing for best battery charging and performance.

I THOUGHT I had it right.
Now back to Ron's question: Is this "CS-144 off of a mid 90s caddy" a one wire or two wire alternator?
Might be a good thing to know...

There ARE CS-144 alternators with remote sensing, but I don't know how to
learn which ones. Here's a listing of a LOT of AC alternators, but without
that information:

The best I can determine from this article, all CS regulators have the sense
lead but its use is optional:
http://oljeep.com/gw/alt/edge_Alternator_Theory.html
<http://oljeep.com/gw/alt/edge_Alternator_Theory.html>There are a number of
cautions and considerations that need to be recognized; I strongly suggest
reading that article, at least the sections applicable to the CS series.
