Trailer wiring tester DIY

[@stevenbieszke9999]

I love the remote add! I am working on building one myself

[@scottgardner3064]

Nice Job, I was looking at building one of these that had the switches but this made so much more sense. Thanks for the idea, and steps, keep the awesome ideas coming.

[@Scottthesigncrafter]

Thank you and glad you like it. I was going to build one with the switches like you but decided to take it one step further and go with a remote setup. The remote and the cordless battery for power source make it so much more functional. Thanks and please post pictures of yours when you get it done!

[@jasongoshorn6940]

You could totally clean that up. Also, we've been running 18v batteries and it doesnt hurt anything.

[@premiumtattooparts]

Thank you, great idea 💡, I'm going to make one where I work we have over 100 trailers.

[@Scottthesigncrafter]

It will come in handy for sure!

[@vrpeppers]

Awesome! I need to make the same one 👌🏻👍🏻

[@Scottthesigncrafter]

This thing has been a great help with testing trailers. I love it. Post up what you end up making, would love to see what others come up with. Don't forget a bout the 12V power socket I added later but not shown in the video. Lets you hook up a power probe which was a big help in testing.

Might add a low voltage cutoff to prevent killing the M18 batteries?

[@rosstga]

This is a similar concept that i have for mine. but its a great use of the 18v battery and i do think the wireless makes it simple to use.

[@saulestrada2544]

Great project sir, thank you very much.

[@Scottthesigncrafter]

Thank You!

Genius on the the remote and relays! Do you have a flasher in your setup so that the turn signals flash? Also, I think you can wire in the flat plug wires with a receptacle poking through the box and be able to test both flat plug setups and 7pin setups.

[@Scottthesigncrafter]

I thought about adding a flasher but didn't see the value in that. If the lights come on when I activate and send power to them for the L and R turn signals I know the lights work. No real need to make them flash to test them. I also thought about adding a 4 pin plug to test those trailers but instead I just use an adapter I already had that goes from 7 to 4.

[@simpson1704]

Howd you hook up your relay to your fuse block, your fuse block to your trailer harness?

[@harlandrake266]

Good job man!

[@Scottthesigncrafter]

Thank You!

How is the operating range for the remote. Looking to build this, l just want to make sure the range of the remote is adequate.

[@Scottthesigncrafter]

I've used it on a 32' gooseneck trailer before with the box up front and remote about 10' behind the trailer to see the lights. So I've successfully used it at about 45'. This is with my antenna sealed inside the case. I'm sure you could get better range if needed if you drilled a hole and stuck the antenna outside the case.

[@enragedplantera5585]

Why use an m18 and a stepdown instead of a m12

[@Scottthesigncrafter]

I looked into both. M12 would work good also. I went with the m18 because I didnt know how long the testing might take so wanted the bigger battery capacity. But either option will work

[@silverghost9]

Could have used 3 18650 batteries which cost much less and elimates the converter, adapter, and expensive cordless battery. There are other cases that would be less expensive.

[@Scottthesigncrafter]

There are lots of ways to put one of these together, this is just how I chose to do it. I happen to have a bunch of m18 batteries already so my battery was "free". And if it dies I have plenty of backups so don't have to wait for 18650s to charge in the middle of a job. No need to buy any 18650 or other batteries when most guys already have a cordless battery platform in their shop. You would also need to put together a charger for the 18650 batteries, I already have chargers for my m18 batteries. As for the case, this one was just easy and available so I went with it. It's also weatherproof so working outside in the rain or snow isn't an issue.

[@rosstga]

Also thanks for sharing

[@BrentonCMB]

Is there any possibility to get a link to wherever I can go online to order these things to assemble one of these...

[@Scottthesigncrafter]

Added links in the description to the parts from amazon. Thanks

[@rambocall9300]

how did you program the remote

[@train4905]

Exellent

[@Scottthesigncrafter]

Thank you.

[@twohandsworking896]

cool

[@Scottthesigncrafter]

Thank you and glad you liked it.

[@sergiobanegas658]

Where is the link?

[@steve1810]

did you do a wiring schematic?

[@Scottthesigncrafter]

I do not have a schematic but explain where most of the wires hook up in the video.

[@bear4389]

Quit talking! More do….

[@Scottthesigncrafter]

Sorry I was trying to be thorough in the details so pretty much anybody would be able to build one of these to benefit them testing trailers. Thanks for watching.
