Battery isolator, year 2000, alpine 36

[Brianna]

I suspect that my old blue diode-based isolator should be replaced as part of my battery compartment update.
It is 20 years old, after all.
I have the wiring diagrams from the ACA but I can't read the isolator specification. It looks just like the 200A Cole Hersee unit on Amazon.....but would that be a good fit?
And by fit I mean fitting in the same bolt holes as the old one.

Some have gone with battery combiners.

...guess these units can fail--but don't recall much conversation on this issue?????? the new-style combiner sounds like a good solution....the old-style isolator creates the need for the DuVac exciter requirement on the engine alternator.....[eg, alternator can't "see" past isolator for battery voltage level.....]

Exactly, if upgrading to a newer or bigger non Duvac alternator, a necessity. I have had the diode type isolator fail on a couple of coaches.
