Trying to put lights on my 2N..12V light kit purchased at Wally World..Nice bright lights and will look good..Comes with complete wiring harness with relay and fused line..Temporarily connected them to a 12V battery a couple of nights ago just to see how bright they would be. They worked fine..But now that I have mounted the brackets to the side of the hood, I cannot connect the wires without it blowing the fuse..You have a white and black wire to each light..all wires are connected just like their diagram shows and loike I had it when I tried them "in the box" a few nights ago. All connections at the lights and other connection points are covered with plastic so I am sure that no connection was touching anything..I am not an electrician so I am not sure why a simple set of lights needs the relay but all I can figure is that the relay fried for some reason and now it is causing the fuse to blow when the wires are connected to the battery..Any thoughts???You would think that at least occasionally, a simple thing could go smoothly from start to finish..... .

Gary,

Any chance there's a grounding wire inside the light fixture, connecting one of those 3 wires to its case? If that's true, it could be causing a "short" if the polarity doesn't match that of your tractor's other wiring.

You might try removing your light fixtures temporarity - just let them "hang" and not touch anything. If the short goes away, that should give you an answer. Or peek inside the fixture, and see if there's a grounding wire or strap that goes to the fixture's case.

That'll be the next thing I try. I went back and read the instructions again and was sure that somewhere it would say "since all new cars are mostly plastic imported from China" you will have no problem finding a place to mount the lights without shorting them out....Thanks

The relay will turn the low current switch connection into a high current connection so the bright lights will have all the current they need and not take out the switch.

The fuse blowing means that there is too much current flowing through the fuse. Either there is a short in the wiring, or the circuit is pulling more current than the fuse expected. If the tractor is still 6v, the voltage will be half of what is required, so the current will double to make up for it. That would blow the fuse. Get 6v lights, 12v won't work. If the tractor is 12v, there is a problem in the wiring. Disconnect one lights one at a time, see if the trouble goes away, then trouble shoot the portion of the circuit that is blowing the fuse. Look for pinched wires, that's a popular problem.

Tractor is 12V neg. ground. As someone suggested, I am going to unbolt the lights from the side of the hood, then apply power and see what happens.Nothing was mentioned in the instructions of having to insulate them from metal mounting surface..Thanks

Gary..... ....despite your protestations, ya miss-wired yer lites. You doubt? Disconnect 1-wire (ea) from your headlites. Now turn on your lites, (they shouldn't lite, buttcha never knows). Blown fuse? Yes, it ain'chur lites, its yer wiring. NO? connect ONLY 1-lite, Blows yer fuse? Yes? you've found yer problem, fixx'em. NO? connect the other lite, itt'll blow yer fuse, fixx yer problem..... ....Dell

Sorry, I am so dumb, but I am not understanding what you are saying. All wires are plugged just like the diagram shows. Each light has three wires(black, white, red) red goes to yellow on the wiring harness, black to black and white to white..One other connection at the relay can't be plugged wrong.Fits only one way..Switch has three prongs and it says red to the center prong and the other two on the rocker switch just determine if the lights are on or if the"park light" is on. If these two were switched it would just cause "park" and "headlights" on to be in the opposite position..All that is left is the red and black...ground and positive loose ends.....What am I missing???

"All that is left is the red and black...ground and positive loose ends"
That looks suspiciously backwards?
Suggest you double check what's actually the circuit here and mistrust color codes.
Where is fuse in circuit? Before the relay? If it is, just disconnect the lights altogether with that plug and see if the fuse blows.
Kinda what Dell said.

Gary, the one thing I don't see in your post is this, IS YOUR N CONVERTED TO 12 VOLT? It will make a difference. Ron

Yes, I did the conversion several months ago.When I got the tractor it had no generator at all. The old fellow I got it from just made sure he had a good hot battery for the day and he was good to go. I just found the problem but makes no sense..Nothing was said and no provision for insulating the lights from the metal hood/bumper or whatever you mount to, BUT when I check for continuity between the light mounting bracket and the wire connections at the lights I am getting continuity through all wires back to the mounting screws/brackets..Dead short looks like to me. ?????

Take out the bulbs if you're troubleshooting with an ohm meter, that'll remove the short you're seeing. If it doesn't, it's real.
