Hey guys, haven't been on here for two months or so. Had to postpone my project due to the bad weather, waited passionately until it gets at least a little warmer outside. Now it's time to get busy.

The thing is that, keeping up the tradition, the first Sunday of March all members of my family gather annually at my parent's place. So just to be on a safe side when needed, I decided to check the condition of the truck and trailer (haven't walked them since the early November). Surprisingly, found the truck is in the perfect working condition, probably will do some minor changes (oils and filters). Pleased with the results, I continued my inspection. Noticed that the wiring on the trailer got a little rusty, so I'm not sure if it's going to work at all. Thinking about getting one of those trailer light testers, has anyone tried them already? Its takes me forever to get the trailer connected to the truck, and I'm just looking for a simpler solution to check the wiring. Any help is greatly appreciated.

Well you don't necessarily need to hook the trailer up, just the light harness. In my opinion this is how I check my lights, so I know there isn't a problem. My 7 to 4 pin connector has lights to check the truck, I've never used any tool to check the trailer. You could use a multimeter and check for continuity between the ground and the other wires, if there's continuity the bulbs are good as long as there's no short.

I got a tester for the truck end like that, it works well enough and easy to grab pretty much anywhere. Don't think I spent much on mine, so it's a cheap way to quickly check when you hook up to a trailer and nothing works.

Also have a home made one for the trailer (power supply with harnesses and switches).
