Plug the tester into your tow vehicle's socket. The tester should have one or more indicators that will alert you if it detects an electric current. Most testers have an indicator for each function. Test each system in turn and check your results. If the tester responded to each system, then the trailer's wiring system is the likely source of the problem. But if one or more of the tests results in no response from the tester, your tow vehicle may be at fault. [links]
If your vehicle's lighting system is working, the next step is to use a trailer wiring tester to check the socket on your tow vehicle. You'll need to make sure your tester fits your tow vehicle's socket. Some testing kits come with multiple attachments, letting you use the same kit to test more than one kind of wiring system.

Some wiring problems are easy to fix. If two wires are connecting to the wrong connection points, it's usually just a matter of using some wire cutters, a wire stripper and a crimper to swap them. Others might require a visit to a mechanic. The important thing to remember is that if the wiring isn't working properly, you can't travel on the road safely. Other drivers could misinterpret your actions if the wrong lights activate on your trailer as you drive. [links]
This is very easy & straightforward. You can us a mulitmeter or a test light. I prefer a test light.
I friggin hate dealing with trailer wiring. It's either the truck harness or the trailer wiring. or both. grrr.
You can use your multimeter or just a simple test light. Depends on how you wired it. Each circuit will still show voltage without the trailer attached ie turn on a blinker and that junction in the plug will show voltage on your meter.
OK, here's a unique situation. I've gotten my rusted hitch removed (prev. one fell off towing a stump - glad it happened in the woods and not my trailer with a load). Put a newer hitch on so I can physically tow now. But the PO had wired in a trrailer wiring harness and tucked it up under the body.
