Converting 12v to 110v


I have an electric boat winch that I'd like to use as a winch to lift the top of my jeep off in my garage. How do I convert the 12v winch to work in my garage?

Use a 12 volt battery.

How many amps does it pull? If it's 150A @ full load this could get messy.

How much does your jeep top weigh? Lifting 100# 6' in 10 seconds is only 0.1 hp. A regular car battery wouldn't mind this amp draw for a short while. If you do this, use jumper cables direct to the battery terminals; we don't want fuses in this circuit.

Connect it to the Jeep's battery with jumper cables.

and if you don't have an ammeter to check current draw, use your dome light.
The starter motor takes about 200A and dims the light because the battery does not have zero internal resistance.
The dimming while lifting the top can then be judged and compared to the 200A draw.
