The issue with trying to fuse the winch is that a motor draws a lot more than full load amperage on a start. I am not well versed in DC motors background is AC power but an AC motor can instantaneously draw six times or more the full load amperage on the start at 0RPM before it starts spinning. DC motors are a directly a function of Ohm's law you would need to know the resistance of the motor and the actual voltage drop across it at the instant of a start. This is called a locked rotor amperage.
You size fuses for the motor starting curve to make sure they do not blow on a start. That fuse you linked may work, but you would need to know what the motor starting profile looks like. If you notice, that fuse has a delay curve that is time and current dependent. The motor starting curve would have to fit "under" the stated performance curve for the fuse.
Joined Jan 9, Messages Location Indianapolis. I've heard of people using or amp circuit breakers car stereo stuff without issue. The vast majority of the time your probably not going to be maxing out your winch so likely won't be hitting the max amp draw. Dunno, just a thought. Would be worth a try with how cheap they are. I've had a solenoid stick on me before. It's not fun so I use a heavy duty marine switch. Easy peasy. Any thoughts on this Switch? Specs are: amp resistive load amp inductive load amp overload They seem to be built very heavy duty and perfect for an install on my Cruiser.
But, my limited understanding is that an electrical motor is an inductive load. Wondering how the amp blue sea marine switch compares. Get yourself a Heavy Duty solenoid. I don't know, my has been wired directly to the battery for over 20 years, never had a problem. Maybe I'm just lucky. Joined May 31, Messages 2, So how many amp rating would i need for a M Warn? Yes, very lucky indeed Lucky you didn't get into a front end wreck causing the power cable to short out on the chassis causing a fire or have an iced over solenoid freeze on you or have some punk kid activate the winch from your hand held remote plug using a paper clip and either crush or burn down your rig There are a number of reasons why I wouldn't want my winch connected directly to my battery constantly.

Thread starter In5ane1 Start date Dec 22, In5ane1 New member. Im gonna hook up my winch today. Do you need to fuse a winch? Maybe instead of asking "do you need" I should have asked "is it recommended" Power, ground and its ready to go.
Most winches have an inline fuse somewhere close to the motor, at least my old Smitty winch did and my Warn does as well. In an ideal world, users will install a fuse and a isolation switch to protect your winch and vehicle from the worst case scenarios considered possible. International orders are shipped using Fedex.
