Michael, I hate to point this out, but that big red cable connected to the relay closest to the fuse block (3:04) and then later actually installed in the 80 (top right of the fuse block @ 7:47) is cooper-clad aluminum. Doesn’t carry as much current and is more brittle than pure copper. I’m sure it’ll be fine for your application for now, but keep an eye on it. May need more maintenance. Love the videos/community. Stay safe! ⚡️ 🏕 🚙

@dobrzpe 4 жыл бұрын

are you sure? it looks like high-quality audio power wire to me. how can you tell? keep in mind tined-copper wire is silver in color and is corrosion resistant. CCA wire is copper colored... it's hard to tell from a video! i was just wondering what clues you were picking up on so i can also learn. nevermind! at 3:44 you can read it as "CW Designs" - a quick search for their wire confirmed it *IS* copper clad aluminum. GREAT EYE @robertnelson! so, yea, CCA wire isn't all 'that bad'. (notice the quotes) CCA wire won't carry the current that full copper wire will, which could lead to more heat due to the aluminum causing more resistance. something to be aware of!

I see the point you made with negative switching but what if your dash switch negative wire get shorted before the switch? Your accessories will come on. This mean that trouble shooting could be hard. And this is for all wires. I would do it for the accessories themselves as you do but to me, the dash switches should be before the relay to not get power to the relay at all time. You could just run one power wire to the dash and connect every switch to it. Then return a wire from each switches to the relay then ground. That way you got only one "hot" wire in the cab if everything is off

Thoughts on using relays that have fuses built into them? I've seen a few of those where you can just attach a fuse to the relay, rather than having a whole separate fuse box

@luchaDor 4 жыл бұрын

So...essentially, the accessory switch on the dash is used to cycle relay switch ground (85) from Ungrounded (off) to Grounded (on), rather than power between switch from off/on (86). (86) is always powered, its the Ground circuit (85) that goes through the firewall & through the switch, thus completing the circuit, thus sending power through (87). Got it.! Power & Ground & Power connections from the Relay are still (obviously) required to route from the relay to the lights, etc...

Anyhow, I am wanting to wire a 50 watt ham radio, along with other accessories by using the following setup: Running 10 gauge fused power and ground wires from the battery to a fuse block, using the fuse block's power and ground locations. Then power a 4 prong relay to the fuse block and grounding the relay back to the fuse block, using this relay to control the radio. The radio would also be grounded to the fuse block. As for powering the relay, I would be running an ignition controlled power source directly to the relay. Does this make sense or is the arrangement an accident waiting to happen?

Well done! I wish I had been able to see this when learning to wire my Baja racer. Speaking of which, two electrical items I learned from racing; 1. was to use small pop up circuit breakers instead of fuses. That way if something pops you can keep resetting it until you find the issue and fix it without wasting all your spare fuses (yes, I had a few extra circuit breakers too, just in case one failed!). A little more expensive but well worth it. 2. For long wire runs, twist the wires around each other. It reduces vibration on the wire run thereby reducing wear and tear on the wire covering. You have to really plan for it and it does take more wire but well worth it. And us Land Rover guys know what started that fire...All Hail Lucas, the Prince of Darkness and He Who Releases the Smoke Gods! ;-)

@jacobkelley257 4 жыл бұрын

So just something that's confusing me (a mechanical engineer) is that a switch should only function if, when it's open, one side of the switch is a different voltage than the other. If they were the same voltage then when you connect the 2 sides together, then no current would flow and nothing would happen. So when you say the switch is "negative switched" and there are no hot wires in the cab, I'm not sure that is correct. But considering I'm not an electrical engineer, I could somehow be wrong. If someone knows more I'd like to know.

Wiring always scares a lot of people, and this is a good overview. One thing I noticed is I haven't seen fuse "boxes" or "Blocks" that have a ground wire. Typically a fuse block is simply distributing power from a larger circuit to various smaller circuits so no need for a ground. One other item that concerns me are those components seems to be amazon cheapies. I would recommend going with a little higher quality components. I but my components from ceautoelectricsupply.com I make no commision from any sale there but have always been satisfied with the quality and Customer service.

86 is power for the switch. it can be piggy backed off of the same wire feeding 30 OR run through it's own fuse on the fuse block. all it does is give power to the switch. it doesn't need to be a large wire and doesn't need to be super-high current power either. :)

Yup. What dobrzpe said! That's in diagram #2 showing the white wire going back to the + lead on the fuse block.

A lot of people have probly not messed with vehicles from the 60's or older. Switches back then were a lot bigger, wiring was bigger, and you had issues with high current equipment (blower motor, headlight switch) still getting wires hot. The relay came along and changed that. The power to operate a relay is minimal. I think I've read it's .02 amp for one of the Bosch style relays. What does this mean? A less heavy duty switch can be used. And smaller wiring can be used from the switch, to the relay.
