Inasmuch as my old PD 7655 no longer charges my batteries, one of my
options is to ADD a PD 9200 charger/maintainer with a charge wizard.

If any of you have done this, correct me if I'm wrong on the install.
As I understand it, install goes like this:

Connect 9200 wires to the pos/neg to the current distribution panel
OUTPUT side, leaving everything currently there intact, plus the
proper chassis grounding, of course.

Two questions: If I do that, will the 9200 supply voltage only to the
battery for charging, and the current converter still runs the house
lights, etc.?
And
My old 7655 put out a max 15 amp charge rate, the 2300 can do 45, 60,
etc. So am I going to have to rewire all the way to the battery with
heavier wire?

Any input appreciated.

You might want to take a look at this before you start:

As for the size of charging wire, you don't say what you have
now. You are going to need at least AWG 8, and larger if it's a
long distance.

There's a chart of amperage draw on this page, towards the end,
that might be useful:

Thanks. One of the issues that I need to deal with is that the old
7655 does not have a separate charging section. It's kind of
integrated with the converter. If I need to disable the entire
converter portion, that's going to require quite a bit more.

The simplest way - if you have a suitable place for it - is to mount the 9200 near the batteries, run appropriately sized wire from it to the batteries, and leave the wiring from the 7655 to the batteries in place. Then disconnect the ac wiring in the 7655 that feeds the dc section - which will take that converte out of action, and leave the dc loads connected to the battery just as if you had no ac power. (In reality, the loads will be powered by the battery if you don't have ac, by the 9200/battery combination if you do - and since the wiring from battery to 7655 is big enough to handle the existing loads on battery, no need to change it).

Went to the Progressive Dynamics website and looked around - found the owner's manual, service manual, and a 'basic operation' document for your converter (www.progressivedyn.com then service department then discontinued products), although it's a little fun figuring out -exactly- what applies to your unit. Looking at the 'basic operation' document, other than the transformer and diode rectifiers which provide power both to the coach loads and to the charging section (so must be working), the parts involved in charging are the charge control board (which you replaced), the current limiting resistor, the scr, and the auto-reset circuit breaker. You can measure the current limiting resistor - if it's open, replace. Jumper across the circuit breaker -if that starts it charging, replace. If the resistor and circuit breaker are ok, that only leaves the SCR (or a bad connection in this circuit). The circuit breaker appears to be on the back side of the fuse panel next to the charge control board, so probably not too hard to get to - the scr and resistor(s) appear to be in the dc module which appears to mount on the back of the power center and probably won't be fun to get to.

Hope some of this helps.

I don't have even a fraction of your experience but what would be wrong with going
the inverter/charger route I previously mentioned? The Trace model 812 I have seems to be a "smart" charger, makes no noise, is useful as an inverter and only needs cables to the battery and to be plugged into a wall socket. You can set the voltage so the charger in the converter never even runs. A tenth of a volt isn't going to burn out anything.
