When it comes to wire gauge, size does matter. Hagerty’s 12v enthusiast, Matt Lewis, gives a basic explanation of the importance of proper wire gauge and …April 9, 2019 at 9:30 am #24321Skye Fuego
i got a question. my wire that goes from the starter to the positive terminal of the battry is short. ( my car was broken into and they stole the battery) can i buy the same gauge wire and solder it together ?April 9, 2019 at 9:30 am #24322IncognitoTorpedo
Jesus, I can smell the insulation smoke from here.April 9, 2019 at 9:30 am #24323Val Rigoli
You only told half the story, and did not mention the hand in hand and extremely important 'resistance over distance' scenario and how to calculate for it!April 9, 2019 at 9:30 am #24324Barb Melle
From Leo: Good demonstration. BTW, be aware that the kind of plastic they use on insulation is really toxic when it smokes. Stay healthy Matt.April 9, 2019 at 9:30 am #24325TommyMacDaddy1
There are so many details to wiring things safely-wire gauge is important-so is the jacket temperature rating, compatibility with fuel and oils, proper termination and many other factors. Be aware. Solder and shrink sleeve all connections. BTW- solid wire provides more current capacity then stranded wire, for a given gauge-but should NEVER be used in a vehicleApril 9, 2019 at 9:30 am #24326AngryRed Banjo
12 volt enthusiast, lol gotcha!April 9, 2019 at 9:30 am #24327Charles Dyer
Good info !!April 9, 2019 at 9:30 am #24328Matt Robin
No replacement for displacement engines and wireApril 9, 2019 at 9:30 am #24329my name is 905
Plus it's really stinky too when it cooks up,yuck! ▪☆☆☆▪April 9, 2019 at 9:30 am #24330mr740
What you forgot is that manufacturers wil underdimention wiring as much as they can to save money. Sure, your headlights will work just fine with something like 16 gauge, but would benefit from 12 or 14 gauge to decrease voltage drop. Cheap connectors will last past warranty, then after that it`s not their problem…..April 9, 2019 at 9:30 am #24331Beefalo Bart
Had to rewire a few boats years back. One I had to rewire and hack after I didn't inspect it prior to launching it. Got out for night fishing with guys from the shop. One of the guys tried to fire it up after a few hours of off and on use. The idiot who owned it before us had used the wrong gauge wire and it was solid core home type wire. It melted from end to end leaving us with no way to crank the engine 2 miles from the landing at 2am. Trolling motor was done the same way and took some odd hacks to get enough wire to run the trolling motor to get us home safe.April 9, 2019 at 9:30 am #24332Errtu Zarathos
Never understood awg.. only morons give smaller number for bigger cross section of wire.. like us has ended up with 0, 00, 000 wires… Cos that makes sense.April 9, 2019 at 9:30 am #24333Colin D

Whats a gauge 1 wire, and what happens if you need a bigger wire? the gauge system running backwards seems counter intuitive. For example thousand kilowatt lines im assuming are much bigger than whatever a gauge 1 is. How do we then classify that? There is a limit to how small a wire can theoretically get but at the other end of the spectrum you can hypothetically have a block of metal the size of a moon thats insulated that could handle unthinkable amount of power. Not that this is something we've ever built or that there is even enough copper in the solar system to do so but the extreme example is to illustrate the point im trying to make here.April 9, 2019 at 9:30 am #24335traeng
Always use largest wire everywhere? got it.April 9, 2019 at 9:30 am #24336Jeff Barr
Again the metric equivalent system makes more sense. Smaller number = bigger wire…..SMH.April 9, 2019 at 9:30 am #24337Jerry Miller
also stay away from aluminum wire. In some data applications they try to sub in something called cca copper cover alum. at any rate less current carrying for a given wire gauge plus brittle.April 9, 2019 at 9:30 am #24338Ozzstar
Who else was wired up while watching this vid? 😳April 9, 2019 at 9:30 am #24339That guy who cannot abide
Something I've found that works well on old cars I would buy (and not want to invest heavily in them) – hook up a second negative cable. Old electrical cables/wires corrode inside, or sometimes develop breaks in some of their wire strands. Too, the cable or woven grounding strap going from the engines to the firewall were fully exposed, and flexed all of their lives. I'd go to the parts store, grab whatever pre-made negative-lead (in those clear plastic boxes up on the wall) had an eye at one end for a bolt, and whatever connector I needed to attach it to the older-cable's battery post clamp. I'd then run that 'second' negative cable from something like the head, the alternator bracket bolt, or what-not, back to the battery. It just about always made the start motors spin faster and made the vehicles run better.April 9, 2019 at 9:30 am #24340Tired Again
I've seen lots of cobbled together wiring! Nice simple explanation of correct wire size for the load. You can't over stress proper over-current protection! Use the correct size fuze or breaker for the wire size and electrical problems become an inconvenience not a disaster!April 9, 2019 at 9:30 am #24341Rafael Torchio
The correct wire and a quility fuse. Bad fuses from china melt the housing and break the cirquit past their amp capacity.April 9, 2019 at 9:30 am #24342Jeff Williams
Thank you very informative.
