Wire 12v like a PRO - EVERYTHING you need to KNOW!! 

Arguably the best 12v wiring explanation out there. So many are over-complicated or vague. Even as someone who understands it quite well, it’ll was refreshing to watch. #teamrelay

Best video about 12v that I’ve ever watched. It’s inspired me to have a crack myself instead of paying someone else (I’ll start small). Thanks for all the amazing videos you’ve made this year. Cheers and Merry Christmas

Mate, this is such a great video. Covers so much but so clearly explained without harping on about anything.. you have smashed it 👏 🙌 👌

This was without doubt the best 12v video I have ever seen 😎👍 thanks for putting this up for us 12v nubs 😁 have downloaded it for later use 😊 Keep well mate and have a GREAT CHRISTMAS 😉🍺

One of the best 12v videos I've seen. More of this tech stuff would be great, you've got a knack for it. One thing I will add for those learning about earthing is that cable size is dependant on the full length of both positive and negative cables combined. So say the accessory is 2 meters from the battery, you would need to size the cable for a 4 meter run (2 meters positive/red to the accessory, 2 meters negative/black back to battery). However if you have a good body/chassis earthing point right near the accessory, you only need to size a 2 meter run of red cable. I used to assume running twin core for everything and always earthing back to battery was best, but for some accessories that can mean needing a big fat 16mm2 twin core (red and black) cable compared to say a 6mm2 single core (red only) cable. Both methods are appropriate and safe - but one is about 1/3rd the overall thickness, a lot cheaper and way easier to work with especially when dealing with firewall grommets etc. Just need to ensure good earthing straps which you have explained so articulately. Hope I have all of that correct. Cheers mate

instantly subscribed man, best explanation of 12v power I've seen on youtube, this video should have 10x the amount of views it does. Thanks Tim!

Just found your channel via your Patrol ute chop videos which were super impressive! What a great video - learnt something new with the 24v stuff! Keep it up, cheers 👍

The best video I’ve seen explaining all this stuff. Well done mate, you succeeded in what you set out to do with this video.

Merry Christmas and Happy New Year mate. This is my go to channel to gain information. As usual, very informative and easy to understand. Thanks for all your hard work this year. 🔥🤛

Very well done. Provided alot of clarity for me being an electrical ignoramus! Thanks for all your awesome content Tim, looking forward to enjoying more in the New Year. Have a very Merry Christmas!

Awesome video mate. You say you don’t normally fuse your switch circuits and only light circuit. Generally what we do is we run a fused control circuit for all our switches and just loop in between switches. If there not connecting to and existing switch circuit from factory. Control switch circuits should still be protected.

Such a good video which made it easy to understand. 12 can seem so scarey to new players but this will help so many people. Good job timmy👌👌

Great Vid mate, explaining electrical can be difficult but youve nailed it 💪. Merry Christmas & happy holidays.

Bloody loved this video keep up great work Merry Christmas and happy new year

Brilliant video Timmy!!! Basics and easy to understand. Merry Christmas and Happy New year

Great vid Tim, it basically explains what us electricial dummies need ta know 👍

Merry Christmas and a Happy New Year Timmy. Thanks for all your Great Video's this year.

Very informative video. Have a Merry Christmas 🎄

nicely explained, simple to the point. thx for the all content in 2023 mate. bring on 2024. have a wonderful xmas n a great new year Tim.

What I took from this. Is that running a winch at 24v is like making a crack head winch. I wont hear otherwise. The sound they make is spot on too..

Well done Timmy. I'm confident that your tutorial has and will help many to understand DC circuits. Happy new year! Cheers

Brilliant explanation. Awesome vid.

You’re a legend. You explained that so well mate. Another great vid! Merry Christmas.

Unreal video Tim, love how simple you explain things

Great video mate, keep em coming!!

Another EXCELLENT video, have a Safe and MERRY CHRISTMAS 🎅 🎄 and a Happy New Year 😊 Thanks for all your videos 📹

Well done mate great video merry Christmas

Gday Timmy, Merry Christmas and all the best for 2024, this was a great video mate, very well explained, cheers

Thanks for the video mate

Love these videos bro keep them coming

Thank you for that easy to understand explaination. Have a very merry xmas and a happy new year.

I love these types of videos they simplify things for the average dummy like myself now I can hook up my light bar properly 👍 thanks Tim 🙏

Great vid Tim

That was the first maths class I’ve enjoyed since grade 4 thanks for explaining running 24v accessories Timmy

Nice, simple and informative video, reminds me of my first Telecom class as a trainee tech! But seriously this stuff is important for all 4wdrivers to know. I had to rewire daughter's GU, previous owner a Land Planner clearly knew nothing about electrickery....spaghetti wires everywhere, some with bared ends too. Well done Timmy.

Love your content mate, im an auto sparky new to tassy on the west coast so i check out your stuff before going to some of spots. Great video honestly would love to see you get into more detail, always wanted yo film alternator and drive rebuilds but couldnt ever get the delivery right so itd be awesome to see you do it in a way thats good to watch. Also theyres alot more you can do with relay circuits ie: latching relays, multiple triggers, use 30 as an input on a change over relay to heaps and heaps more.

I agree also - team relay. Relays are the best

2:05 if you go to the next setting to the right, and press the right-most button, it will give you a proper Continuity Tester mode that will beep when there's continuity. Much easier than trying to look at a screen when you're upside down under the dash trying to trace some wiring 🤣 Sometimes you'll still need to use the resistance reading if you're trying to find a dodgy wire that has high resistance but still enough continuity to trigger the tester, but for general fault finding, the continuity tester mode is much easier.

Yea mate awesome stuff once again

Awesome video man, really indepth for free information 🤙 Going to be useful when i start wiring up my patrol with the 12v goods Everything was easy to understand and appreciate you breaking it down I'm probably the worst sparky to walk the earth but this was awesome. Thanks heaps All the best for chrissy and new year brother 🎉

Very detailed and informative mate, I teach automotive and think this is really bloody well done. Your best yet, 😊 Have a safe and happy xmas to you and family 🎉👍

Great content man

Bloody brilliant

Merry Christmas mate 🤠👍👍

I’ll be coming back to this video a lot in the future cheers bud

I’m dyslexic asf and I’ve struggled to understand all this for ever. I understood this down to a T …. Thank you! Looks like I’ve got some adjustments to make 👌🏼

Good to see you’ve picked up where 247 just throw 10k worth or red arc at it. Awesome video!

Another great vid mate love it. Whens the merch drop?

Cool vid Tim, like the tech vids. When are you going to do merch so can support you more?

I hate wiring not my favoured job,, time consuming to get a neat job somethings you just cant rush ,,,,,,super stoked the TJM pro air has very good harness pre wired with duel air lockers option,, was simple installation ,i did run thick 100amp 8bs cable as it pulls 45amps and its mounted under back seat , ,i did invest some coin on wire cutter crimping tools and crimping lugs back last year when i built my offgrid solar battery system for my shed , having the correct tools helps when wiring and good soldiering iron ,although i rather crimp then solder but sometimes you need to join a wire ,,,,,,,,,,,,,,marry Xmass mate happy new year ,

Can’t wait for the gu build 💪

Nice nice nice 👌

As an auto sparky I (hope ) I knew all this . But love the delivery and believe this should be taught to our young techs

I have always wired the positive through the relay, not the negative. The way you have it the LED light is hot all the time. You did the switch the right way but the load is wrong. The relay should be hot, not the light, because typically the light is a long run of wire but the relay is close to the battery, under the bonnet, and fused via the vehicle's maxi fuse(s)

Timmy, you shouldn't feel you need to explain why you are just talking to the camera, all your content is Gold no matter how you are presenting it. Safe holidays mate.

Picked up my phone at the right time. 🤘🇦🇺

Tim - I have a redarc 2000w inverter, unmounted and a Landcruiser 100 series hdtfe twin battery. I don’t want it permanently mounted. I want to run cable from the auxiliary battery in the front of the Landcruiser to the rear of it in the tyre jack compartment to connect to the 2000w inverter. Can this be done without installing a battery in the back next to my inverter?

Great vid apart from the Body/Chassis earth. A fair few modern 4wds, especially Navara have a very poor chassis earth. Only the engine/trans and body are earthed.

i dont get why people keep refering to negative connections as earths. Earth is a protection system that under normal conditions shouldn't be carrying any current. Negative connections are the return paths for the current, to complete the circuit

Go the Patrol! good to see ! This is really good ! I liked building my own with jaycar components. but best to start with a plan first. as my circuit board got way outta capacity once i started adding things 🛻😎🤙📹

timmay/southpark.jpg is back!
