I have a 24V highmount warn motor in front of me, how do I find out how many HP it is?

I have no idea about winches, so yer :finger:

my understanding is that the HP figure is the same no matter weather 24v or 12v

but hey I may be wrong :lol:

Power = Volts * Current

From what I know there are 2.5, 4.6 as standard HP, then you can fit a 6hp motor off another low mount warn winch, there is a thread on here about upgrading the motors to 6hp, go the search for more info!

that gives you the power in watts , not Hp

also you would need to load the motor up to get the true power as it wont drag much current at all free spooling

the hp figures on winch motors are fairly meaningless anyway - the power rating is generally given at peak efficiency, and you're almost always operating a long way from that.

if the winch works and you aren't competing. don't worry about it. get stuck, winch out, be happy.

1 watt = 0.001341022 horse power
or 1 kW = 1.341022 bhp

the warn site should have current draw at free spool and various levels, this should help if you want to measure it

assuming he has a 100 amp ammeter lying around - even at no load they draw over 50 amps. most multi meters max out at 10 amps.

just email the numbers to warn, they are pretty good at customer support.
