Deep Cycle Battery Charging From Alternator
Hello, May I ask for advice regarding charging deep cycle batteries from the alternator? I have read older threads, and understand opinions vary. The previous two 100Ah deep cycle AGM coach bat...

Perhaps the man is not old enough to remember Mallory Ignition DUAL POINTS.
This 1950's product delayed the opening of a coil charging primary circuit so it would saturate the inductor (coil) and raise primary voltage and multiply the ignition coil secondary response (voltage)
There is nothing disproportionate about the weight difference between a lawnmower armature and a very popular starter motor for big block GM starter motors, such as the 3510. The 3510 armature weighs 5x the amount and saturation watts therefore will be roughly 500%. Five times the energy when the field collapses.
My fingers used to withstand 27 volts and 35 volts respectively on 24 and 32 volt marine systems. Saturate a 12-volt V8 armature and then collapse the field. WHOPEE to bare fingers. I call this "The Fred Flintstone Effect" Unbelievers will not need a cup of coffee to further awaken for the morning.
Peak INVERSE voltage can affect many scope meters. Does your scopemeter automatically measure peak-to-peak or is the baseline a measure from null?
Vessels have many electronics that can have enough electrolytic capacitors (radar) (sonar) (gigantic stereo amplifiers with 2-4 FARADS of capacitance) to skew any onboard test.
And examine any device that has the capability of becoming an unwilling voltage doubler.
Just when you think you have everything well in hand, it's back to the finger and saturated inductor test :)
Frank Oropeza, owner of Transpo Electronics, was greatly surprised at the resistance of the Delco 1116405 alternator voltage regulator showing superior resistance to TV spikes. Why? It was the 1st voltage regulator to employ PWM control. Basically the first components to employ 200 PIV rated components, not 50 or 100 PIV.
And finally there is nothing like success to failure ratio in reducing premature lifespan failures. It's not merely a voltage regulator's power connection to Q1 that kicks the bucket, it's the voltage sense lead and voltage divider network that takes a beating.
This is a fun field to tinker with. On the Kelley II every 24volt power lead to main accessories had a 42 volt avalanche rectifier connected. Motorola 2535 devices. Within a month every one had failed. I had to replace with 55 volt units. The failed device in this case was the hydraulic over electrical 5-stages electric steering, navigation.
In the 36 years since the Kelley was launched higher voltage voltage devices has been made more common and less expensive. Thank God.
But without a doubt severe snubbing of both positive and negative oriented transients have improved service life of electronic devices.
Given the correct discrete components I can make make basic automotive circuits EMP proof. But not blue tooth -- their sensitivity and gain are far too sensitive.
Same for household ALEXA devices.
EMP and CME is another poorly represented to the public phenomenon.
For folks who are interested. Discover the difference in Tesla units the quantification between whole body exposure intensity to Magnetic Resonance Imaging and the Infamous 'Carrington Event". Or the ionospheric thermonuclear shot event. Starfish Prime.
The object here is to reduce failures in sensitive RV circuits or Why does this always happen in my RV accessories?
If transient voltage events are rare and of little consequence why has General Motors, Nippondenso, and other manufacturers spent hundreds of millions of dollars converting all power rectifiers in their alternators from standard silicon to TVS snubber avalanche 28-32 volts? GM did it in the late 1980's. They also redesigned the 1116411 voltage regulator, then the 425 then the 437. Each update included one more TVS. Was it a mistake? All the avalanche and TVS devices?
