ok checked the threads... the mention of unplugging and replugging a relay..got the old cogs grinding...seems when I hooked the original set of works back in 2002...something similar happened...disconnected the battery to check the terminals..and it worked.. will be braving the winds in abit to try that idea out..soon as Walking Dead is done
LOL

so for the past hour, I disconnected the battery, un-plugged/plugged in every relay and check for any other fuses other than the main 4. Everything is working as it should...except for power to the black and white wires that branch off from the bundle that feeds the flasher/caution lights. Yet, the work as they should.
hmmm

I could be wrong but those wires might only be hot when you have the switch turned to run the headlights only. I believe the thought process their is so you are not running work lights off the back while going down the road. Again, I could be wrong but I recently ordered LED lights to hook up and I know when I tested the wires that's what I found.

 

[RitchElbe]

You're correct. They only had power when the lights switch was on. Which is how I would use them. But now no power, yet the switch still works as it should. I'm curious is there's a hidden fuse somewhere

Oh Dear Lord...I just made the mistake of actually calling John Deere...20 mins of them constantly saying...we can redirect you to a local deal or another dealer with your issue...local dealer looked like a lost cause when I described the issue, next one is an hour away...both have about a 3 weeks back log working on equipment....grrrrrrrrrr John Deere..what the heck happened to your company!

Well my tractor powers up like this...key switch needs to be turned to on position, then light switch is off 2) flashers only 3)work pos. headlight/rearlights 4)road pos. headlights only and flashers. No xtra fuses that I know of. Make sure your add on light wires aren't reversed connected. I've had a few add on lights that the wire colors were not what I THOUGHT they be. In my photo the blue spade connectors are power taps for my worklights and the lights are grounded to the ROPS using the flasher mounting bolts.

DFB: check my original post, I had it wired correctly, I've ran work lights on it for years, but had to replace due to neighborhood brat and a BB Gun.. so when the main lights turned on..so did the work likes on the ropes. the problem arose when the wind blew a good gust..which shook the wires enough that they pulled apart. The secondary line which ran to the ground..caught the hot lead..that's when all the lights dimmed for a nano second..now nothing comes of the hot lead..yet...the 30amp fuse that I am told controls the lights on the fuse rack mounted next to engine on the right firewall is fine. Everything works ( well the glow plug issue still remains from years ago ) but no power to those two hot leads...which makes no sense..if power was lost...and there are no other fuses....then it should have killed the rest of the lights as well

Fuses should be (2) 10A, (1) 15A, and (1) 20A.

According to the book

Glowplug/Starter 10A
Accessories 10A
Flasher/Warning Lamps 15A
Headlight/Taillight Lamps 20A

Good Luck
