I'm working on my Double Dually Mutt Truck project, and I need to wire the whole thing up. I decided to try the whole system on a table to make it easier to see and work out the bugs. That was a good idea, because not everything went as planned.
Part prices I show are the price at the time I bought them, it will probably change! Links for the Nilight stuff below:

If every school in America had a teacher like this guy to teach basic mechanical skills to our youth then this country would be much better. This guy would make an amazing shop teacher!! Awesome video!! Everyone should watch this!

They used to. Then the school districts pushed as hard as they could for everyone to go to college, because the schools would get more money for students who moved onto college. When I got into high school back in 2008, they got rid of our auto shop & metals teacher to replace them with more arts classes. I was lucky enough to get into working on cars as a child & taught myself pretty much everything from RU-vid, believe it or not! 2 years after I graduated, I was making almost $50k a year. Had a really nice vehicle and my own place that was a rental, but still. HS now set up a majority of their students for failure because I believe that not everyone is meant to go to college. We need to bring back trade classes!

Another modern safety addition is the flashing side marker lights. If you wire your (2 filament) turn signal fixture ground wire to the positive of the marker lamp, then ground the marker lamp normally. The side marker will dim and brighten, providing a side visible turn indicator! I discovered this trick used one of my cars from my youth, after wrapping tinfoil around a blown fuse to get me home. Instead I melted the entire rear wiring harness. I learned a great deal about automotive wiring that week!

@BallBusta Год назад

About a month ago I had a little issue with electrical myself. Was fixing my brothers mower, the issue was electrical, managed to narrow it down to the starter. Checked online for a replacement starter, that shit was like 200 bucks (which wasn't in my budget), so I cracked the starter open to see exactly what the issue was. Turns out, all the springs that press the brushes into the starter were rusted to pieces. So I looked online, found a brush replacement kit for only 8 bucks, and that included the springs. Learned a lot in the process about starters, solenoids, fuses, and tracking down issues with a multimeter. Needless to say, I learned a hell of a lot more since watching this video. Thanks for the upload!

@CrazyHamSales Год назад

Great video.. hint for making LEDs work with the two wire flashers or electronic flashers if they don't flash. Add a resistor from the output side of the flasher to ground, this makes it think there is a greater load then just the LEDs connected to it. They sell load resistors for this purpose when you want to install LEDs into older vehicles, but instead of putting them on each light I just put one at the flasher so there is always enough load to trigger it.

@davidolson9909 Год назад

Wiring has always been tough subject for me. Your explanation from basic start to end was excellent. You are a great teacher, and Thank you for taking the time and effort you put forth. This video is one of the best on the net, and have saved it for future reference for my son and myself. Thank you James. Great job!

@wackowacko8931 Год назад

3 terminal flashers in cars were used to flash the side marker lights (new requirement around 1970) during the "off" period of the turn signal lights. Turn signal light would be on while side marker light was off, turn signal light would be off while side marker light was on. In the 80s they let auto manufacturers do a wraparound turn signal lens instead of requiring a separate side marker light. 87 and 87A on the Bosch relay were the "activation" for the relay, you would feed V+ to 87, or ground to 87a to turn the relay on. The ground trigger was for things like a horn switch, where the button on the column grounds out to turn on the horn relay to activate the horn.

Well, all ya need is a steering wheel, tires, drive train and your ready to go for a ride! Awesome table build if I ever seen one... Lol Joking aside I did the same thing to my Zero Turn lawnmower. I live on a highway and I wanted light and flasher's so the idiot drivers can see me mowing . It had no light at all. I added headlight, tail lights, flasher and turn signals just like he did in the video. I had to use a flasher for Led's as well. The guy next door thought I was nuts until he seen a car slow down as it passed... Awesome! Thanks for the cool video! LLAP 🖖

You could use a in line resistor to trick the flasher into thinking you have incandescent builds. Great video with lots of information.

@vintagetintrader1062 Год назад

In Europe, Australia and many other countries, we by law need to have separate rear indicating lights. Been many study’s that having yellow (Amber) turn lights reduces the amount of rear end crashes. Something to do with the way us humans are wired ;) I’ve imported a few Mustangs into Australia, we use to have to convert the rear wiring to amber indicators. Most Australian states finally accept red indicators.

@koenvangeleuken6544 5 месяцев назад

very nice video. i like simple. i've made wiring for several vehicles, 3 cars (unimog) and 2 bikes. the unimogs were diesel, so thats simple to start with. then i used only 1 fusebox, always connected to the battery. i also fitted a heavy duty battery cut off switch. so if i switched off the engine, everything still had electricity; when i left the car i switched off the battery switch and everything was dead, you could not forget lights or anything. worked fine. and of course, i used rear light units with seperate rear light/brake light/indicator.

Since my car battery is beneath driver seat - I just hooked positive from battery to a switch that turns on the switch box for accessories (and negative to some frame crosspipe). To turn any accessory - you have to switch power on - and then which accessory you want.

@karl3050 Год назад

I see some comments, as I always do, about adding load resistors to make LEDs work with old style flashers. I stay away from using those. They get hot. Very hot. Borderline fire hazard hot. Plus, why make a system inefficiently guzzle when it wants to efficiently sip? It's the difference of hazard lights flashing hours vs days. Do you need your hazards for days? Hopefully not. But an embarrassing number of times I have come out after 10 hour shift to my lights still being on, going "oh crap!" and still starting my vehicles right up.

2x 60w headlights and 2 LED tail lights, turn signals, fuel pump, interior light, stereo, electrical seats, power windows, power mirrors and so. The power for them all comes from the ignition switch to the fuse box from which all other parts are wired up. Can an ignition switch handle so much power? And the wiring with the middle fuse box ignition, not even one relay needed?

@martinedelius Год назад

At 16:33 you show that you run power from the "battery" fuse box through a single fuse to your ignition switch. Doesn't that mean that both the "on" and "accessory" fuse boxes get all their power through that single fuse? That might not be the best scenario since it means you'll need a pretty beefy fuse and wire going from the "battery" fuse box to the ignition switch. My suggestion would be to take the wire coming from the fuse in the "battery" fuse box and connect it directly to the same terminal that has incoming power from the battery.

@LowBuckGarage Год назад

Yes, you're correct, everything going through the ignition switch goes through that fuse. That circuit will be on a 30A fuse, and as I recall my ignition switch itself was rated at 30A max. I really don't want more power than that going through the switch. If there's high draw stuff, it can be run off the "battery" fuse box with a relay, and the relay can be controlled through the "on" or "acc" boxes. That would keep the load through the switch at a reasonable level.

@martinedelius Год назад

@@LowBuckGarage That's a very good point, I didn't consider the amp rating for the switch. If you put a 30A fuse for the switch then that should be plenty for the other two fuse boxes.

@jackallen6261 Год назад

The 3 prong flasher is what we called (back in the 70's and early 80's) a self leveling flasher. The extra ground ran a separate, for lack of a better term, self resetting circuit breaker, which in turn controlled a relay which actually ran the turn signals. They were recommended for trucks pulling a trailer with the extra load from the trailer lights to keep them from blinking super fast. No matter how many lights were hooked to it (within the limit of the relay amp capacity) the turn signals flashed at the same speed.

Best LED flasher to use for regular 4 to 6 light connections I've personally found out are cheap Chinese motorcycle adjustable speed LED flashers! 3 wires I believe and a slotted Pot to adjust for the individual loads of whatever or how many LED lights your running? They're usually under 5 dollars each! And they have all worked out from my personal experience with them 👍Hopefully someone finds this useless information useful? Just passing it forward Lol!
