Explains in a bit more depth than my earlier post.


Bottom line is that it's there for a good reason - to extend battery life by not overcharging.



In a practical sense, batteries in my NW seem to last around 1.5 times as long as my previous vehicle, a Triton, and almost every vehicle prior to that. Which I think is pretty good because the NW, as a diesel, puts a lot more strain on the battery when starting and it tends to do very short trips which would otherwise be battery killers.

Yes my concern would be fried battery.

Im trying to learn here but wouldnt a regulator do its job?

Dumb alternators how do they prevent frying of battery?
Doesnt a smart alternator have this too?

Smart alternators also have regulators. Regulators can and do fail. But not having the alternator running full blast all the time reduces the chance of regulator failure.

So does that mean Smart alternators and their regulators tend to last longer than dumb alternators?
Alsobecause of this. The batteries will last longer too?

From what i read smart alternators were for emissions reduction?

[QUOTE=reciprovac;532111]Mike , Do you mean that the negative from the Aux battery has to be connected below the currrent sensor ?

NO! The Aux Battery is connected in the Alternator/SEnsor circuit EXACTLY the same way as the starter battery.

Connect the Positive of the Aux Battery to the Positive post of the Starter Battery.
Connect the Negative of the Aux Battery to the Negative post of the Starter Battery.

If any of the loads connected to the Aux Battery are also grounded to the Body (e.g. Lights which only have a single positive wire and get the negative return via the light body), you will be BYPASSING the current sensor.

I dunno mate but the way my chargers work 240 volt or DCtoDC is they supply amps which push up the battery voltage, by reducing amps they stop batteries overcharging & drop the amperage right of to the float voltage value of the storage battery being charged.

A 120 amp alternator certainly isn't producing 120 amps when your battery is full & 14.2 volts to my knowledge.
I'm probably wrong but if the alternator was runnig "full blast" i'm sure your battery would be A molten mess, if your alternator wasnt fried first?

Dumb alternators draw engine power & fuel but, smart alternators when not charging use less juice also I think?
