50DN alternator / Regulator

rusty · February 20, 2014, 02:21:57 PM

Does anyone out there have a 19020413 delco regulator for your 50DN ? If so how is it wired ? Ground is Ground. Field to F1 on the alternator. Battery to Battery. Ignition one of two places 1 from the battery or 2 from ignition 12 volt.Sense to plus side of shunt or not hooked up at all. Also is there a ground strap from F2 on the alternator to the case ?

Thank You
Wayne

Mine is 24 volt so not like yours.

What bus?

Wayne I'll look when I get home Tuesday, but I'm pretty sure I won't have the right one with yours being 12V an all the buses I deal with being 24V

BK thank you, I have learned that the regulator I have is a newer sealed type and not like the older black boxes. Gus I am adding it to the 15 I am building to run one of my Ac's while going down the road. The other thread that is going on has been helpful in figuring this out. I have also had some off air help.

I assume you mean an Eagle 15?

The reason I asked is mine has only three connections, but it is 12V so I didn't want to confuse things.

So is the new style regulator the digital type ?

I have the new digital regulator. Instead of a big black box, the digital is about the size of a cigarette pack. Good Luck, TomC

What is a digital regulator?

I'm guessing you mean a solid state!

rusty · February 26, 2014, 05:23:44 AM

Gus /Clifford Mine is solid state and has five connection points and is 4 X 6 X 1 inches but is not digital. It does have a small screw to adjust the voltage, but that screw is painted over. This is a delco product.

No Gus a digital regulator is different from the old solid state,the digital is a better regulator IMO

Rusty,

Gene can answer your question.

OK, so just exactly what is a digital VR? Does it show digits somewhere?

I have a digital voltmeter on my dash but it has nothing to do with digital regulation, it is just a digital meter?? I don't have any idea what digital regulation is??

Balmar makes one...

A voltage regulator is basically just a switch that turns the field coil on and off very rapidly so that the alternator output voltage tracks a set voltage. When the field coil is off, the VR senses the battery voltage, when it is on the VR senses the output voltage. A "solid state" regulator of the old style did this with some resistors in a voltage divider arrangement, a zener diode and this drove a transistor output section that sent the voltage to the field coil. A digital voltage regulator would just do this same job with some integrated circuits like computer chips instead of separate resistors and diodes, probably do it far more accurately and far faster while running cooler and using less power, and probably control a MOSFET output device instead of a transistor.
