I've finally been able to get my stuff together, kick PC squatters off of my computer, and sit down to describe my lighting project.

Let's try to set the scene. I wanted auxillary lighting for my 4100. Since my tractors alternator only puts out 20 Amps, I had to be careful in what I could add to the tractor. Also, the standard light switch wouldn't allow me to only turn on my rear or forward auxillary lights. So I had to come up with another way.

Having gotten my EE degree (Electronically Enlightened) /w3tcompact/icons/laugh.gif and after reading a few posts here on TBN, asking a few dumb questions, and having a friend assist me, I was able to put it all together. Here what we did.

I bought three halogen lights from my JD dealer. Two trapozoidal and one flood rated at 50 watts each. As mentioned, I wanted separate switches to control the auxillary lighting. The picture attached to the first post shows a diagram of the circuits for the lights.

For materials, I used two waterproof inline fuse holders. I made the mistake in buying a fog light relay switch kit. The only advantage to buying the kit was that it had a very good diagram of how to connect everything together. I used about 12 feet of the split flexible conduit (3/8" and 1/2"). Two single throw toggle switches with rubber covers for the toggles for waterproofing. The main wiring from the battery to the two inline fuses is heavy duty 12 awg stranded wire. Between the relay and one toggle switch I used 20 awg stranded wire. Most connections were done using heat shrink and twisting the wire.

Two other photos are provided showing some of the detail.

Here is a composite photo of the switch wiring and the rear light.

Here is the last composite photo.

The first is a picture of the relay and a dirty firewall. /w3tcompact/icons/shocked.gif

The second is the finished product. Well, some finally tack welding to hold up the switches and remove the 200 mile an hour tape. /w3tcompact/icons/eyes.gif

Thanks, Terry!
My 670 also has a 20 amp alternator. I'm kind of surprised one can install such high wattage lamps on a 4100.
The schematic will be a big help to me when I do my project. Since I'm somewhat electrically challenged (Gawd, I hate PC talk...why do I do it??!), I hope I can find a friend as helpful as yours.

Roy,

With all of the lights on, I'm approaching the 20 amps generated by the Alternator. That is why I went with the separate witched circuits instead of using the supplied connectors under the seat.

Is that Kubota orange in the left side of the picture? To finish it off right, I've got some spare BLUE you could use instead.

dummy,

Nope. Just some mastic. The aluminum angle use to be legs on a test bench at my friends job site.

Nice try.... Close, but no cigar. /w3tcompact/icons/wink.gif
