12 or 24 volt, whats the difference

Bill from Scotland · Jan 29, 2014

I just bought a couple of old starter motors, they will do a Perkins p6 or V8 I think. One is 12v while the other is 24v. Why are they different and what are the benefits? Is one more powerful or faster than the other? Just curious.

with the 24 volts you get twice the power with the same amps. wiring could be half as large. starter size could be lots smaller with 24 volts.

Very common on construction equipment and Military stuff to use 24 volts. Starters spin a bit fast and you can get by with smaller wires

So would that mean the 24v would be good on an older diesel that was hard to start in cold days?

Well given your area yes since it is rare that you over in Scotland have many truly hot days. Yep been in Scotland a few times the Holy Lock area. I forget the town there

Yes but..you would need one 24v battery or 2 12v batteries wired in series. The big problem is the method of recharging the batteries. A lot of John Deere tractors were 24v but most have been converted to 12v.

24V on a 12V starter will really wail the engine over.

(quoted from post at 19:24:09 01/29/14) 24V on a 12V starter will really wail the engine over.

I'll bet a 12 V starter powered by 24 V won't wail the engine over very times until it's FRIED.
