It’s always good to regularly check your vehicle and trailer’s electrical system before hitting the road. Albert’s tester features remote-controlled operation, saving him a lot of “back-and-forth” walking between the vehicle and trailer in order to activate the lights manually. A pretty clever way of checking lights when you're all by yourself!
Terrific project, Albert! Thanks for sharing your project with us!
Q: What is it?
A: It's a tester for checking lights and brakes on trailers and checking RV plugs on vehicles. It also has a wireless remote for checking the trailer’s signal lights, marker lights and electric brakes.
Q: What is the main power source for your project? (e.g. electric motor, gas engine etc.)
A: It is powered with a regular 12V battery, preferably a deep cycle one but any 12V battery will work. It also has a charger to plug in while you are not using the tester.
Q: How do you control your project? (e.g. hydraulic control valve(s), electric switches etc.)
A: It is controlled by switches and a wireless remote.
Q: What components are used to perform the work for your project? (e.g. hydraulic cylinder(s), hydraulic motor(s), sprockets, pulleys etc.)
A: I used switches and lights to turn power on and to show which circuits are on. I also used relays, fuses and circuit breakers for safety reasons. And best of all I used a wireless remote so you can stand at the back of the trailer to turn lights and electric brakes on and off. Saves a lot of steps back and forth turning switches on and off.
Q: What design/build challenges were overcome?
A: I had to change my wiring drawings a few times to get it working properly.
Q: If you had to build it again, what would you do differently?
A: If I had to build it again, I would probably include a controlled air line for turning air brakes on and off semi-trailers.
Q: Which Princess Auto location do you visit most?
A: Saskatoon, SK
