Damsel in distress-53 Hatteras 32v system ?s

Now we need a new Post.
Can one of the Admins help here?

There are extras after the FR plate that really makes a difference. The Charles charger does not have and others do.

The definition is more confusing than what I thought; This one (I hope) does not apply here.

Ferroresonance or nonlinear resonance is a type of resonance in electric circuits which occurs when a circuit containing a nonlinear inductance is fed from a source that has series capacitance, and the circuit is subjected to a disturbance such as opening of a switch.[1] It can cause overvoltages and overcurrents in an electrical power system and can pose a risk to transmission and distribution equipment and to operational personnel.[2]

I really have no idea what that means from the web.

What I do think I understand is a anode(plate)/cathode (gated diode or transistor) drives another output diode or SCR. It is a CRUDE design that mostly works but always leaks some current.

Briefly stated now would be; It cooks batteries..

A smarter (but more expensive) system would include a real voltage regulator driven by a feedback lead driving a real charge profile and turnings completely off when the profile is complete (or other demands are met).

A plane FR like the Charles in topic, as I understand, is not a smarter, nor really regulated (charge profile) FR charger.

Again, I'm not an expert. What I see in the field is real. My theories could be off (way off?).

However, what I have resolved in my working history has proved positive.

Anybody is invited to call BS here. Just give me a real education and not a blasting.

Got a beautiful letter back from Lamarche last week comparing 32Vdc chargers and what they had and how it worked.
I will look for their tutorial.
I have expressed positive comments above of that equipment, but 4 weeks to build a mod 41 / 32Vdc charger.

Used one on e-bay now..
