24 to 12 volt conversion
« on: September 13, 2016, 09:35:45 AM »
How easy or hard would it be to concert a M900 series 5 ton to use 12V instead of 24?

Howdy,
Not sure why you want to.
More information required.
There are plenty of devices that will convert (not concert as you posted, music will not assist here :-)  ) 24VDC to 12VDC for accessory use.
I like my 24 VDC systems, I own three.
My shop vans (M185A3 and M109A3) also provide for shore power hookup at 115VAC inside the box.

That is all.

Change the starter, alternator, all bulbs, all relays, horn, cigarette lighter oh and the gauges might not work right either.
Why the obsession with the 24 volt stuff is beyond me.

VERY hard.  Use a 24v-12v converter to power your 12v stuff.  I had a fan, interior lights and usb charger running off mine.

You are neglecting things like glow plugs and other power bay components.

Re: The obsession with 24VDC?  It is not an obsession.
As voltage is increased cable diameter may be reduced [saving $$].

Researching Solar (PV) collectors and the associated battery banks may
shed some light on power transmission line requirements for your edification.
Many systems are 48VDC for this reason.

As it pertains to Green Iron (Military Vehicles) it is a matter of standardization of configurations.
Fewer parts to stock, and stuff is interchangeable to a point.

Carry on.

Forgot the glow plugs.
I understand the wire size stuff. But it just seams the .mil is obsessive with it.
I have looked at a bunch of surplus generators, even with a small engine and a starter that is 2' from the battery they still use 24 volts.

Everything can jump start everything else.
Did that help?

Back to the O.P's original topic.

That is all.

All conversions boil down to 3 factors. If you possess all three no problem. If you possess any two, you can get it done. If you only have one, then you gonna have problems. The three factors are:

1) Access to Money
2) Access to Skills
3) Access to Parts and Materials

Asking the question means Skills are in short supply.
So then its down to Access to Money and Materials. If you have both then your good to go. If you only have one it better be Money.

a more applicable question may be do you need to convert it to 12V?

The reason for using 24volts is still valid. Smaller wiring (saves cost), less overheating, greater available power makes 24v a good choice for larger vehicles, solar arrays, battery banks and etc.

it may be better to install a dc-dc converter or a 12vdc power supply that runs on your 24v system or an inverter/charger that can provide 110/120vac as well as 12vdc. that option will still be cheaper and more versatile than the 24 to 12vdc conversion>
