variable resistor
24v in and 12v out
Wouldn't it make more sense to just tap off one of the two 12 volt batteries for 12 volts?
Self destruct charge?
I would guess that it is something to step down voltage, for either a fan blower or a 24v-12v stepdown. I doubt it would work well for 12v supply unless there was exactly the same load drawn across it whenever it was used though.
Lighten up Francis.
Poser, was that a line from Stripes? If so, that's awesome.....great movie...seen it 75 times.
Howdy! My second guess was adjustable muffler bearing heater controls.JohnTheyve got it correct... its a variable resistor... Years ago I towed a 20 travel trailer, and thats in the electric brake system...
Oooppsss: that's exactly how I burned a good 24v setup and I had to loose one very nice deep cycle dry battery. Because somebody told me to run the radio on one of the 12 volt batteries! Never attempt such a foolish thing. Your batteries will get an uneven load overtime and ruin one or both batteries.
Another thing ,
Current flows through the outer most part of the conductor. Called the skin. The thicker the wire the more skin it has , more current.
That is confusing current with voltage. Thicker wires have more resistance ,therefore less Voltage.
Look at the wiring in your home.
14 AWG wire is not thicker than 10 AWG wire. Which one is designed to carry more current?
You are describing a VOLTAGE divider, not a current divider. A current divider is a set of resistors connected in parallel which "divides" the current through each resistor based on the applied voltage. A voltage divider is a set of resistors connected in series, the voltage at each node is based on the resistance value in relation to the current in the circuit as a whole.2 wire wound resisors connected , is what you call stepped or tapped resistor.
They fall under variable resistors.
They are usually made of 2 or more fixed resistors, incased in ceramic sometimes.
What is it doing there, no idea, but there function is to provide different paths for current to flow to the load. Each path will give different current to the load. They would be connected to some kind of circit control device , switchs, relays .
They are not rheostat type variable resistors or voltage converters.
I said a larger wire has lower RESISTANCE, which most certainly true. For DC the current density is fairly uniform through out the conductor. Skin affect is typicaly only found in Radio Frequencies.Another thing ,
Someone said thicker wires means lower current.
That is not true. Current flows through the outer most part of the conductor. Called the skin. The thicker the wire the more skin it has , more current.
That is confusing current with voltage. Thicker wires have more resistance ,therefore less Voltage.

You should probably also understand the basics of electricity and how to use Ohms Law.But iff you are working on the 40, you only need to know how to trace wires and preform simple tests. A test light and a miltimeter with an understanding of how the device you are working on is supposed to work are the best weapos to have.
At the end, if you get no where and want to ask the more knowlagable members for advice.
For good sake ,provide more details about your problem
just like was stated many times over.
The worst thing to do is jusmp straight to posting without checking things out first to see what you have.
A qiuck look at this thing would have provided a lot more usefull info and if I am wrong, don't blame me for your doings.
