Questions & Answers

Do you think this tool can be used on RV seven pin hookups?

As long as it is the 7 round pin connection, not the 7 flat pins, the device should work. Class 8 trucks use these circuits, however some RVs are just as large and use the same ones. This is only a 12v test light, if you need to test multiple circuits in an RV you should take advantage of a 12v test light instead

Can it be used for the smaller diameter (approx. 1/2"). Are there connectors with 1" diameter)?

Trucks of this kind can be used for this. The standard blade configuration typically used by medium and light duty trucks is seven pins. As a result, the trailer plugs with a diameter of approximately 1 inch do not have seven pins, but six instead. The trailer's auxiliary power line does not connect to a plug with a 6 pin connector.

Does this product have a 7-day turnaround time Does it come in flat pin form?

Does this test equipment verify the open/closed circuits on a 7-way round pin converter dolly, with a standard FedEx ground/ups double connector 28' to 38' long?

You're right, that's what it should do. You will see if the turn signals are on if they are flashing or illuminated, but if there is a closed circuit they will not work

The tester is nice
5/5

Every day, I have to deal with truck drivers due to my job as a chassis mechanic. With this tester you can figure out whether your 7 way has a bad circuit, which will provide you with a clue as to where to search for your With this item, you'll be able to determine whether the wiring connecting your semi truck's 7 way plug to the chassis that your truck is hauling is damaged, faulty, or both. It is always best to use a metering device for the most accurate readings, but if you cannot afford one of those devices, this 7-way tester will do the trick. In order to do quick troubleshooting in seven ways on chassis, I recommend this item to my fellow mechanics.

By using this tool, you save time and by saving time you save You cannot find the source of the light problem when you are pulling doubles, as someone who has done it
5/5

With this device, it's far easier to find the source of the error, whether it's the back trailer, front trailer, nose connector, or tail connector, and you can fix it in a matter of Make it work, get it done, and you'll be on your way. This is a very urgent matter, and we cannot waste time fiddling Make sure the spare light bulbs and electrical tape are in the bag.

This is a great product
5/5

It's well made and makes quick diagnostics easy. Rather than having to constantly look for problems from the vehicle side, using this tool enables you to quickly and easily determine if the issue is from the truck side or the trailer side of the When I compare myself to my coworkers It was obvious that the only difference was a snap on logo and the pricing was radically different from the workers' snap on version. It has been reported to me by many trucks drivers and mechanics that they have never seen anything like this. They say they will get one as soon as possible. I have had it for a few months now and use it almost every day, so far it has held up well. The device seems to be as good as new with no issues with.

That's great
5/5

The tool was so useful, I couldn't imagine how I ever lived without it. A trailer inspection helps to determine if the problem is on the truck or the trailer. Alternatively, you can test to see if the cable is bad by plugging it into the truck and making sure the power is being sent to the socket, plugging the cable back in once more, and hooking the tester onto the other end. As you can see, it is not a good tester for testing low voltage that can still light one light, but it is perfect for checking to see whether electricity is present in the trailer. I found it to be very If you wanted to just use a test light, then that'd be fine, but it's so much easier to plug it in and yet it still works. Moreover, it allows you to show your clients in a more straightforward manner the problem is not with the trailer, but rather with the truck.

The price is too high, but the product works
3/5

It is an afterthought to have a jumper. Testing this system is fine, but using it on the road would be a bad idea. If you were to use it as a jumper/bypass there is no way to secure the plug to it. Jumper piece, which is a thing metal eyelet piece you slide over the shaft of the pin, is an afterthought. The money to build the bypass/jumper should be paid for by the halls.

For diagnosing electrical problems on a truck or trailer, this can be a lifesaver.

This time saver will save you time
5/5

In the past seven years, I've worked on Despite having used pin connectors before, I have never used them on tractor trailer combos. Since I work for an organization that deals with tractor trailer rigs, I thought this tool would be handy as soon as we received it. Little did I know I would put it to use as soon as it arrived. A mechanic should have this tool, since it allows the mechanic to easily identify whether a circuit is powered and which one isn't. You can figure out if a problem is with the tractor or the trailer with the help of this. There's no other way to put it.

OK, I hope I can return this and find There is no problem with everything except the brake light does not work
3/5

I'll have to see if I can get some warranty on this. After owning it for a couple months, I do not think I have ever used the brake light because I don't use it frequently. In fact, I won't say I have ever used it than two times so far.
