One of the best investments you can make is a Trailer Light Tester. They will give you an indication if your Trailer Light is working properly so you can avoid costly repair bills. Here's how to use a Trailer Light Tester...
Indicator that your brakelight is not working - If you have a vehicle with automatic brakes or automatic transmission, you need to check your trailer lights testers at least twice a month to ensure that your brakes are working properly. Simply slide your hand along the brake pedal to feel whether there is any heat generated as the brakes are applied. Hookup your semi-trailer lights to a power outlet with an electric outlet strap. Lightweight, waterproof and easy to use.
Your lights may be in good operating condition, however your wiring may need to be upgraded. Some vehicle manufacturers require that you upgrade to OEM wiring, others may recommend switching to a 'hard-wired' hard-wired system. Check your wiring to make sure it hasn't been damaged during a flood, fire or accident and replace your old wiring with the new wiring. You may also want to consider a four-way connector for your Trailer Lights. These four-way connectors are designed to easily connect your wirings to many different types of electrical circuits, including:
Does your lighting functions work when you turn on and off the air brake system? If your vehicle doesn't already have factory installed lighting functions, then it is very likely that your lighting functions are outdated. Many accidents occur because the person in control of the vehicle failed to manually activate the air brake system, which means that your vehicle now stops unexpectedly even if there are no other vehicles in the road. An Automatic Trailer Light Tester can ensure that your current lighting system is working properly.
When testing your wiring, it is important to have the correct wire colors to match your test panels. The first thing you will need to test are the wires that are on the front of your vehicle. These cables and wires will have a white, blue, or red wire in them. You will need to locate these wires and use an instructable to strip their insulation to reveal the wire. You will then use the soldering iron to remove the wire. Once you have removed all three wires you should place each one inside of a plastic zip bag to keep them from getting any hot wires on them.
Next, you will need to test your brake lighting circuits. For this test you will need two of the same type of batteries, a marine battery and a deep cycle battery. With the correct batteries, you should connect the wiring to a twelveV battery. Turn your RVcheck on and connect both lights to the positive terminals on the battery.
Finally, you will plug the lights into a twelveV power outlet. The test should be performed on both the ABS brakes and the traction control brakes. You should read the meter and the lights to see the amps and volts. If there are any problems, such as the lights not showing anything, the lights may need to be re-worked.
With these tips you should be able to troubleshoot your RV lights easily. RVcheck is a great product that can help you troubleshoot your lights easily and accurately. It is easy to operate and can be used anywhere. Take the time to read the instructions and find out how to troubleshoot your Trailer Light Tester.
