run 12v to sprayer

[JerryG]

jrpoux,
Nice job. I used the same type of switches for the same reason. These switches have worked out real well; I put them on over a year ago. I ran a 4(?) gauge line from the battery to a fuse box that I made. That way everything is isolated from the tractor electrical system. Each circuit has its on fuse. I think the biggest problem was finding the best way and place to mount the fuse box and the switch box. You never know when you will need a power outlet, I have one now and I am currently putting a bank of four in the overhead console that I am also working on.

Thanks patrickg

Your discussion about fuses was very good.
Key points:
Fuses are more reliable than circuitbreakers.
Fuse as close as possible to the power source.
Use large wire. 14 ga is good for 15A, 12 ga. is good for 20A, 10 ga for 30 amps.

Attached is a pic of one of my favorite fuse holders. It is small, can be tucked away inside a box, and uses the standard automotive industry fuses. Well designed fuses, very available, and hard to mis-apply.

I got a good surprise when I checked my M6800 fuse box. It has a lot of fuses. Then I noticed that half of them are stored spares! The fuse box cover has a built in fuse puller. Quality!

I don't like the cheapo cigarette lighter outlets that cost $4, and am looking for a well made one. Any suggestions anyone ?

jrpoux, Although I will probably never use "large" wire on my lil Kubota I have wired power to the center console of my pickups with #4. But then not everyone uses 1.5 million candlepower spot lights, 2-3 ham radio xcvrs, CB, FRS, WX, GPS, small frige, etc. Amps for some ham gear are amp hogs.

Regarding the reliability/longivity of breakers: If you are so fortunate as to find some surplus mil-grade, aircraft. or better yet mil-aircaft breakers, especially the ones for pilot use, then celebrate. These are made to use as a switch as well as to be a circuit breaker. Typically they are well sealed and pretty dust proof. I lucked into some that were lighted. Wired the light circuit to the pannel lights so they dimmed (had to cobble in some 12 volt lamps as the 24 volt ones were already dim on 12 volts.

Congrats on your spares and tool, I have that feature in my Dodge pickups.

Regarding 12vdc (cigarette lighter) outlets. Some of the best I have seen are stainless steel and come with waterproof covers to keep thing nice inside. They were built, I believe, for the marine industry. At least that is the venue in which I found them. My only complaint is that they were not flush or recessed (they protrude less than an inch, I was just being picky).

Thinking outside of the box, some folks just delete cigarette lighter outlets from their designs and standardize on something they like,changing everything to that style. It is certainly a valid engineering solution and you can use as good a style connector (with waterproof covers etc.) as you wish. Of course, as everything is a tradeoff, you have the time and expense of replacing the cigarette lighter plugs that come on a lot of gear.

Jim-
I would use a four pin round trailer connector as made by Cole- Hersee and others. They are weatherproof, well made, and allow for two spares, in case, down the road, you want to power an appliance off the ignition or light circuit. - Stan

Thanks to all who offered help for me to get wired.
After I got the electrical completed, I got an old 3point fork we made for the old Satoh hooked it up and then got my old 25 gal. sprayer that was used with the JD 185 hydro that was stolen and the wheels just straddled the forks and the tongue hooked to the 2910 draw bar. This is so much better than using the stolen 185 to pull the sprayer. Now I can adjust the 3 point to tilt the tank and the mix is "good to the last drop".
Let's see if I can show you a photo.

Make sure you have proper size fuse for the pump on your tractor. That type pump motor can freeze up and make wires overheat. These same pumps are used on RV's and Boats. More than a few boats have burnt and sank because of wires catching on fire./w3tcompact/icons/frown.gif

Hello ronjhall,
Thanks for the warning. Since I only attached to the end of the original "hot" wire and it is only hot when ignition switch is on, I assume the circuit is fused already. I sprayed half tank without any problem but I'll certinly be alert to the overload possibility.
