I am going to rewire a light fixture and need to know what I can do to test it without hooking it back up to the wall. Can I use some sort of battery to test?

you need a 120VAC source, a battery is DC. You could use one of those cigarette lighter converters that allow you to plug in 120VAC devices in your car and hook that up to a 12V battery to test.

However based on your knowledge, this might end poorly.

why would you want to test it before you hook it up? That doesn't make sense.

Just wire it up and cut it on, if it electrocutes you then you may have made a mistake.

Why do you want to test it again? Just put it in and hope for the best

Use your multimeter to test for continuity thru each wire to the socket terminals. If the fixture has its own switch, click it back and forth for open/closed circuit.

Test the light bulb in another fixture.

If you live in the BR area and you get tired of messing with it, I will come take care of it for 150 bucks you buy the new light fixture.

Test to see if a wire is hot with the back of your finger. 120 volts doesn't sting much.

So I don't have to climb a ladder, wire it up, and test multiple times. I need to make sure it's right the first time

And whoever said the pigtail wins. That's what I'm going to do.

Unfortunately no, batteries are DC only while your light fixture requires 120V AC.

You need to apply 120V AC to it, which is what a power outlet will provide. Easiest and cheapest way.. buy a cheap extension cord and chop off the end with the female connectors (the one you insert plugs into). Cut off a bit of insulation on the 2 exposed wires you just created and attach it to your fixture. Plug in the other side to the wall and voila!

While there's a thread open I've got a question too.

Electrical breaker box on the outside of my home has rusted pretty badly and needs to be replaced. It's just a normal panel box with four fuses inside. I'm assuming since it is tied to the meter I need a registered electrician to replace it. How much should that run me for parts and labor? Also any recommendations in br?

Thanks in advance

the circuit doesn't care if it's AC or DC.

It is hard to give a price without looking at it. How old is your house? Is it fuses or breakers? What kind of shape is your inside panel in?

Does the meter box need to be replaced too?

Say what?? The bulb certainly cares. Apply a household battery, or even a care battery to a standard bulb ain't gonna do the trick.
