Help Wiring Work Lights On A 4530

[MUDONTHETIRES]

Hello All,

I previously posted this in the Customization forum and only got one reply although a good one.

I've been reading all the posts about wiring work lights and I think I have everything I need to install some on my tractor but have just a few questions. First, let me tell you what I have. My tractor is a Mahindra 4530. For the work lights install, I have (2) 55 watt traps, 10 gauge wire, 14 gauge wire, (1) 30 amp relay, (2) 15 amp inline fuses and a switch. One 15 amp fuse is for the 10 gauge wire going to the battery. The other 15 amp fuse is for the wire going to "the other power supply in question".

Here are my questions:

1. Do the 15 amp fuses need to be 30 amp fuses and if so, why?

2.The wire coming from terminal 30 of the relay will go to one power supply, probably the battery.

The switch has three terminals:
Switch terminal 1: goes to ground
Switch terminal 2: goes to relay terminal 86
Switch terminal 3: goes to the supply side of the low/high beam wire.

My question is, can I instead connect the wire of switch terminal 3 to the auxiliary wires that is above my 3 point? All 4530's that I've seen have these set of wires. Does anyone suggest a better connection? I have supplied the wiring diagram for my tractor in pdf format below for reference if anyone has any ideas!

Thanks a million in advance!

Mud,
Wow! I installed two round lights on my canopy so I can work my backhoe after dark and just wired them into the existing plow light wiring. Nothing more. I will be installing two trap lights facing forward from the canopy for loader work and will just splice them into the existing upper headlight circuit.

Thanks for the input Brandi!

Does "Wow!" mean I'm making this too complicated?
I have a plow light but wasn't sure if wiring directly into it was too much pull on the alternator. I don't know anything about how many amps I'd be pulling and I'm not an electrician, but I did stay in a Holiday Inn Express once!
All joking aside, most of the posts I've read are clear cut on relays and fuses and fuse panels. Do you think wiring directly into the plow light wire is sufficient enough to run the work lights for 2 to 3 hours at a time without straining the alternator? If so, then I'm all in!

Mud,
Yes, Wow means too complicated. . WATTS divided by VOLTS = AMPS. So your 55 watt light will draw 4.58 amps each. Your 4530 puts out 36 amps by the alternator. If you have two lights and add two more, that makes 18.32 amps, half of your alternator output. If you are running for 2 to 3 hours, your battery will be charged and not drawing much if any amps from the alternator. So only electronics and lights will be sucking amps. Your battery charge light should come on if you draw more amps than the alternator is putting out.

I removed my plow light and added two work lights. This circuit is in with my upper "scuttle" lights above and behind my hood. When I install my forward work lights, I will just wire them into my head light circuit. I don't run all the lights all the time, so I am not worrying about using up my 45 amp alternator output.

I wouldn't worry about adding more fuses unless you feel the wires and they are hot, which means you need bigger wire. I think I used 12 or 14 guage wire for my light addition. Here is a wire guage chart that has max amps for each guage wire.

I know, it's clear as Mud.

Thank you Brandi!!!!!!!!!!!!!!!!!

You just made my life easier! I'll install the two work lights on my canopy frame and I'll tie them in to my plow light. I can turn my plow light on without having my headlights on. So with the flip of the switch, I'll have two work lights in front and a plow light in back. Very Cool!

Again,
Thank you Brandi!

Mud,
Be sure to protect your wires through any holes. I looked at a 4530 on my dealer's lot yesterday and the wiring to the plow light went through a hole with no grommet on it. Ask your dealer for some grommets. My dealer had some plastic grommets. They are good, but not as good as rubber grommets found on small airplanes. I also enclosed my wiring in heat shrink. I don't have a heat gun, but used my hair dryer to heat the heat shrink. It protects the wires a little more. Then I clamped the wire harness to the canopy frame. You can get heat shrink at auto parts stores and maybe the clamps also.

Brandi,

I really like your setup. I'm heading to the store in a few minutes for some heat shrink and clamps. I think I know where some rubber grommets are too.

Thanks again Brandi!

I just want to know what the IPTO HOOTER is...

Brian,
Think Indian. Independent Power Take Off Horn.

[xlr82v2]

HAHAHAHA, yep, I know...

But, what is the horn for? I don't recall ever seeing a warning horn on the PTO... Does it go off when you leave the seat or something like that? Or, am I not thinking Indian enough yet?
