Performs every type of service including power injection, measurement, ground testing, polarity checks, continuity testing and components activation
Easy-to-read volt-ammeter allows you to read voltage and current at your fingertips.
With a flip of the output switch, you have positive and negative electricity via the probe for powering up electrical components like cooling fans, relays, etc.
Simultaneously uses the hot lead and the ground lead to activate components right in your hand
Instantly identifies positive, negative and open circuits
Tests for bad ground contacts instantly, allowing you to follow and locate shorts fast without wasting fuses
Instantly checks continuity of switches and relays.
Circuit breaker protected
Built-in Flashlight enables you to work in the dark
Audio tone indicator allows for no-look menu scrolling once users are familiar with menu tone assignment
20ft (can be extended via extendable cable port) cable provides excellent accessibility to test along the vehicle

Used for DC 6-40v cars, motorcycles, trucks, buses, engineering vehicles, vessels, tractors, mining vehicles and other vehicles that use DC circuits.

Highlights:
1. GODIAG GT101 4 in 1 PIRT  support circuit breaker finder, fuel injector cleaning and testeing, relay tester and current detection function all in one device. The whole device only 2.5lb, lightweight easy to carry. Working voltage range 6V-40V, support variety vehicles. With GT101, you are all set!
2. GODIAG GT101 circuit breaker finder can be used to diagnose an open circuit, short circuit, detect positive and negative circuit and pulse current of power lines. When the vehicle's headlights, turn signals, lift windows, sunroofs and other functions fail, GT101 can be used to detect the circuit voltage or supply power for these components to find out whether it is a circuit problem or a component damage.
3. GODIAG GT101 covers the detection of fuel injectors and relays, as well as the cleaning of fuel injectors. When the vehicle has difficulty in starting, acceleration and fuel consumption, etc, it is necessary to check the fuel injector. When the car's headlights, turn signals, horn and the engine starter do not work, and there is no problem with these components after detection, you can check the relay switch.

Good stuff at a good price
Model: NewSLS50_52
Works well and sticks well. I used a roller and it has been over a year and everything still sticking as good as day i put it everywhere. I didnt use any adhesive but I did wipe everything down with acetone before I applied. Good stuff at a good price

Working perfectly. Install of stereo equipment and carpet left me wanting some heat and sound resistant materials.

BUY THIS ONE!
Model: NewSLS50_52
This is one of the good ones. There are other brands just as good, and manny brands are worse, but this handles well, rolls down easily, doesn't come off at all easily, and adapts to dips and curves like a champ. Appropriately heavy and dead, I'm happy with the way it smothers panel resonances and even at muffling direct sound, like a big hand over my Uncle Harry's eternally noisy mouth. You can rip the foil but you have to work hard at doing that. Remember to buy a brayer; you can roll overlaps nice and thin. Also remember to pre-wipe the sheet metal with a decent solvent like acetone or Stoddard/Varsol. It should last forever.

Good stuff, but watch the temp
Model: NewSLS50_52
I used this in my single cab pickup truck (89 ford.) It only took half the box (10 sheets or 25 square feet) to do the floors, but I bought the big box because I plan to do the doors, back wall, and maybe the roof as well. One thing I learned is that the temperature matters when you’re doing the installation. It was around 55F when I started in the evening, and when it dipped down into the 40s the sheets would not stick to the metal, and were hard to compress with the roller. That’s why I ended up only doing the floors and not any vertical surfaces; i will have to wait for a nice hot day. The other thing is that the foil layer on top is razor sharp at the edges, definitely wear gloves! I didn’t notice until after but I have little papercuts all over my fingers. Aside from those things, the install was easy and straightforward. The sheets cut easily with scissors, and any goo that ends up on your hands or scissors can be cleaned up with acetone (nail polish remover), or lacquer thinner. I would use this stuff again.
