Roll Bar Wiring TC29D

thcri · Oct 31, 2003

For those of you that put lights on your roll bars, how did you wire them? I wired mine to the molex connector that is right by the right flasher. Works great except the lights are one when ever the key is on. Also if the lights are on when I hit the glow plugs I burn the main 30 amp fuse. If I wire to the battery which would be the best then I take the chance of leaving the lights on when the tractor is not running. I could put a DC relay in the circuit to cut the lights when the key is off which would be the best but I was just wondering how every one else wired theirs in.

murph,
Put a switch inline before you run to the lights. That feed is hot all the time that the key is on.
Turn key on, if lights are on, shut them off then start it.

Yeah I did have a switch but I got on the tractor tonight and forgot I had it on. So when I hit the glow plugs I popped the fuse.

I wired a rear light to the connectro left at the bottom of the rops which is also 'hot' when the lights are on.. except that I used a light that also had a built in switch.. so i hav ethe option of not havint it on.. etc. The addition of a waterproof switch will solve your problem with little added wireing.

What's wrong with me. I have the switch in there, I'm in the Heating and Air Conditioning business, I know I have these time delays on my service shelfs, just put a time delay in there for 30 seconds!!!! Or just remember to turn them off if one before starting. But with the time delay you would not have to worry about someone else getting on the tractor and blowing the fuse.

I ran a dedicated 8 guage wire from the battery to a relay, and a switch, and then up the ROPS. I am however running 4 lights from it, I didn't want to mess with the factory wiring in any way.

murph,
Take a look at this crude schematic........think this would work?
When you want lights......flip switch and then push the momentary puhbutton. That energizes the coil and the lights come on, they stay on until the tractor is shut down or the switch is turned off. They can be turned off at any time by turning your switch off, but if you forget to flip it off, whenever the key is turned off, it de-energizes the relay.

Inspector,

That looks like it would work pretty good. I did look for a time delay relay as said before down at work but they only went as low as 18 volts DC. Your schematic looks like it would work pretty good. I already have the momentary switch.

Thanks

Murph,

You mentioned that you connected to the "Molex" connector located with the wiring of the right flasher. I have had a heck of a time finding a mating connector. Every connector I have purchased is either slightly too fat, or too short. I am presently using two bullet crimps that push into the connector. I have inquired at my dealer for the mating connector, but they had nothing to match, in fact, they were surprised the connector was there. Can you tell me where you got yours? Thanks /forums/images/graemlins/wink.gif for any help you throw my way.

Boomer,

I found mine at NAPA. But mine too is not the right size. It works ok but it is not a tight fit like I would like it. I have ran tape around it to make a tight seal so moisture won't get into it. Even with the tape I am sure moisture will get in it. The thing I may try is buy a flat 4 way and just cut two barbs off of it. The 4 way seems to be just the right size.

I think I found the answer for the connecting plug. Hopkins Mfg. makes "Hoppy" trailer wiring devices. In addition to the 4 pole flat connector, they also make a 2 pole version which should marry-up just right with the plug on the tractor. It comes with 24" of wire and both male & female ends. It costs $2.50 and is available from Ace Hardware online. I hope this helps!

The connection kit that comes with the version of the rear light that can be provided right from the NH dealer comes with two individual connectors and not a plug. Apparently even NH (or maybe Speaker - the manufacture of the light) didn't want to bother. The kit gives you one male and one female crimp on connectors. I just crimped them on, plugged them in and taped up the whole connector assembly. Very quick and electrically sound.

Boomer33,

Thanks for the information! It is impressive that you pulled this string out from last November; a true tractor lover, I can see.

My wife always laughs when she sees me running thru TractorByNet, or looking at tractor specs and home pages. She tells others that I spend most of my computer time running "Tractor ****". /forums/images/graemlins/grin.gif

( My wife... tells others that I spend most of my computer time running "Tractor ****". )

I love it!.. Something similar at my house.

Both me and the wife work some nights.. and I usually get home between 10:30 and 11:30, but she gets home about 12:30-1:00. I sometimes spend that time hitting the tractor subs. When this tractor 'affair' first started she would come home wondering what I was looking at hunched over the computer, I told her looking at tractors... suspiciously she didn't believe me.. unitl I showed her.. Now when she comes in and asks what I'm doing, I just mutter 'talking to my girlfriend.. be with you in a minute'... to which she says.. well at least its not tractors.. winks at me then walks on and starts getting ready for bed...

Yeah I really got in trouble the other night, my wife caught me looking at a tractor with the hood off. /forums/images/graemlins/blush.gif /forums/images/graemlins/blush.gif

Here is a photo (I hope!) of the 2 pole flat connector. I got it at Advanced Auto Parts for $1.89. It is 12" long You can make two 6" pigtails by cutting and crimping or you can use as is to make a 12" extension for the original plug in the wireing harness.

Boomer33,

We all thank you for the effort in taking the picture and submitting it for the world to review. It is "Tractorphiles" like you that continue to make this site worth my first 20 minutes on the Net.

Thanks! /forums/images/graemlins/smile.gif

Boomer33, You seem to have a knack for finding handy wiring connectors. I need your help.

I want to "splice" into my wiring harness on my TC40D so I can hook up a 7-pin trailer connector to power my tail lights/flashers on my hay wagon. John Deere offers a 7-pin kit and has the necessary wires in the tractors harness. Unfortunately, NewHolland does not.

I wanted to avoid splicing the wires to the tractor's taillight/flasher assembly. I am looking for a "T" that would fit before the tractor's tail lights assembly. The harness is triangular in shape and has three pins. I would also need a piece to plug into this "T" that goes to the the 7-pin connector.

I see on the new TC55DA that is at my dealer's lot that the 7-pin receptacle is already there but I suspect it is wired directly into the tractor's harness so that probably won't help me.

Terry,

Boomer33 · Jan 23, 2004

Terry: I would much prefer to not cut & splice factory wireing also. I have used "T" adapters on several trucks in recent years and the make for a very clean installation. I think the key to successfully finding an adapter for your boomer would be to determine if any auto mfgr has used that same shape & sized three wire connector in a car or truck. Once you determine that, you can search by vehicle year, make, model etc. on the Hoppy website. They seem to have every possible connector covered, but you must search by car or truck; NOT TRACTORS!
