I'm with bob.. something is wired wrong. It is also possible that out o fthe 3 wires.. 2 are hots, and one is ground, an extra ground tat is, as it seems that the chassie / case is also ground. Evidentally you are mixing the hot in with one of the grounds.

Hook it up with jumper wires and isolate which ones are hot and which are ground. Opening the lamp shell up and / or using a VOM will greatly help in this situation. Also ensure that the relay is wired correctly, and that it is not switching hot to a ground.. etc. Check the switch as well.

I agree with Bob too - that it's wired wrong. I just think the problem is between relay/switch/power. Shouldn't have to switch or unground the wiring to the lights when they are already wired into a pre-wired plug.
And does the relay switch both park and head or just head? Then one switched hot would bypass relay direct to park and other switched hot would go to relay.
Sorry, but the Bear's game is pretty bad so I don't have anything else to do but spout off here!

Your lights have the one side of the bulbs grounded the the light housing, PLUS one of the wires coming out of the light is also a ground.

You have the ground and power wires switched so you are feeding power to the side of the bulb that is grounded to the case.

This shorts out the system when the lamps are mounted to the grounded metal on the tractor.

You need to switch the power and ground wires connected to each lamp. (Or open up each lamp and remove the jumper wire connecting one side of the bulb the the lamp housing, since you don't need that anyway, with the separate ground wire.)

So, this means that the wiring instructions that came with the lights is wrong???I have them wired exactly as their instructions say. Not doubting what you say but..each light has a red, white and black pigtail out of the light then each drop out of the wiring harnass for the lights has a yellow and a black and a white..It plainly says yellow to red, white to white and black to black...So are you saying that the yellow should be going to the black or white rather than to the red like the instructions say??Or maybe the white to black and black to white?

Gary,

You ask "So, this means that the wiring instructions that came with the lights is wrong???", and elsewhere you state you have followed the instructions!

Well, IT DOESN'T WORK, so either you haven't followed the instructions, or they are WRONG!

Apparently, each light has 3 wires, 1 - common ground, 1 - for the "bright lights", and 1 for the goofy "glow ring thing".

Open up one of the lights, and find the wire that is COMMON to the bright lights and the "glow ring". This is the GROUND, and apparently is also connected to the lamp housing. Whatever color the wire from this point is, it MUST connect to the grounded wire in your connecting harness.

The other 2 wires from the lamp will be self-explanatory. Applying power to one will light the "bright" light, and applying power to the other will light up the "glow ring thingy".

No, I'm not saying the lights to relay is wrong. I'm commenting on your earlier post that said somenting like :
the remaining two wires red, black, ground, power.
There is no indication here that the red from the lights is the same as the red out the other side of the relay.

I should just be keeping my mouth shut here, but I still wonder about your black/red polarity choice on those two remaining leads. Black is "normally" ground on low voltage stuff, not hot as it is in 110v.
If your tractor is correctly converted to 12 neg you should not have to worry about the lights being grounded. Pulling that might make it work, but it sure isn't "fixing" it.
How is the relay wired to the switch? What do you really mean by parking lights? Is the relay switching both head and park? Is the relay intended to be grounded to turn on either side or is it intended to get a hot wire?
Is the relay in a metal case that is intended to be grounded or is it electrically isolated?

You are correct in saying that the black is ground and the red goes to the power supply(+)The relay is all plastic enclosed unit..When I say park light it is actually a set of off road lights and all the "park" as I am calling it is..in one position on the rocker switch a colored ring glows on each headlight, then in the other position of the rocker switch, the headlight comes on..actually the glowing ring in the "park" position is of no use but it is there and is intended to work..actually in the wiring of each light the"red"wire from each light is the tail of these "glow rings/park"..the other two wires from each light is a black and a white and it says that white goes to white and black to black when connecting these two wires to the wiring harnass...and this normally would make sense....does any of this make sense? and/or give you any other clues? Thanks for your help.

Now that I'm shooting my mouth off, I do note that in trailer wiring and other places black and white as a "pair" are often black-hot white-ground. If you have your lights apart you should be able to verify which one is grounded.
On the other hand you have said the lights wire to a plug which is fixed so I wouldn't think those have to be swapped.
You also said there was a red on the switch and a remaining red for power or ground. How are you keeping those separate? Is there a separte 3 wire bundle for the swicth and another two wire bundle for power?
I agree with you it should be simple and every thing off the shelf today is going to assume 12neg.

Bob, I wasn't trying to step on you here.

Can you tell us what lights you have. Might be a wiring diagram on the web to look at.
How are you determining + and - where you're picking up the power? If you're looking at a pre-conversion marking that will have switched when you converted to 12neg (depending on what previous owners migh have done).
Have a voltmeter to verify polarity?

Did you buy this as one kit or did you get the park/head switch separately? I think we're missing a piece here.

All came as a kit..Premade harnass..3 wires dropping out at two places for the headlights..three wires taped together going to the switch..relay plug already in line and only one way to plug in the relay..Just looks totally idiot proof but I must be a better/bigger idiot than most....

So you are attaching wires at light? Thought those were already in plug?
Pair of wires drop off relay for power/ground?
Got a product name I can look up?
Which color was grounded in the light?
What if you just swap the red/black power ground wires? Again, are you sure that red is connected to battery + and that rest of tractor is battery - ?
Have a test light or better yet, voltmeter?

Here's a hypothetical wiring diagram Assumes White is common/ground in the light

Relay - Power(+) - Switch Center
Ground - White - Relay - Ground
Headlt - Black - Relay Relay - Switch Head
Ringlt - Red/ylw- Relay - Switch Park

Relay needs big wire power and ground.
Smaller power runs to switch.
Switch head runs back to relay to switch higher power.
Switch Park probably just runs back to ring light, although it might go to a second relay?

e-mail is mkii62 at comcast dot net , if you want to do that. Threads getting a lil long.

found the light. not a wiring diag. on my way out the door for a couple hours.
if there's a diagram, tell me where and/or I'll look harder when I get back. send a n e-mail
