Today's tool of the day is a multimeter. It is a fairly basic tester for electrical current. This tool can be used for detecting issues and troubleshooting bad connections.
The lights on our trailer stopped working and I used a multimeter to track down where the electrical current was broken. Turned out to be this box connected to the car. Ordered a new one and voila issue fixed.
No idea how much fiat it would have taken to fix through a mechanic. My multimeter and I fixed it for $40 + tax.
