john deere 4105

[acuser]

My signals nor flashers work. fuses are all good and power switches at signal switch.
Im assuming after the switch it must go thru some type of flasher.
I have tried looking up the part number for flasher but cant find it listed in the parts index does anyone know the part number.
If anyone has a wiring schematic that would be great.

I don't have the schematic for the 4105. If no one else can come up with an answer for you, visit your Deere dealer and ask them to bring it up and make a copy for you.

Edit: The flasher on my 4300 is in the turn signal switch, according to my schematic. Not sure if that is of any help at all.

I will also guess that the flasher is in the turn signal switch although the 4105 has a different switch from the 4300

I wasnt aware the dealer would print schematics. The turn signal switch only has three terminals but I guess it could be in there. I will stop by dealer later this week.
Thanks for your replies

Not all dealers will print schematics for customers. Some feel this is giving work away by showing people how to repair their own tractors. I feel it is good customer service. Most people have difficulty finding their way through modern tractor schematics since they are more complex than ever, especially the ag tractors. Majority of customers are more willing to pay dealer to do the work when they see how difficult it can be to navigate some of the diagrams.

Called a couple of dealerships this morning. They were unable to find flasher nor tell me if its in switch or not.

On your 4300 does the turn signal switch have three terminals. Im thinking it will have more than three.

From the schematic, looks to be more than three.

Tx Jim thanks for the specs that pretty much confirms the turn signal switch is just a regular spdt.

Looks like Ill have to order the repair manual to figure this out. I want one anyway:laughing:

On my 4320 the turn signal switch along with the display mode switch is how you access the onboard diagnostics. This seemingly minor problem maybe more than that. Also I purchased the maintenance CD versus a physical manual. The CD was only $75. It is a searchable PDF file/ ctl f. I am not sure what the manual will cost. Just an FYI. Later.

I just took a band saw and carefully cut the blinker box open on my jd4500 since the handle had seized and would not move. A little lube and motivation its working like new, and there is a little motor in the thing that makes the blinker blink. More than 3 wires because its also lighting up some other lights in the turn signals. I used hot glue to seal it all back up and its working fine.
Its a big clunky thing inside and not hard to mess with, if yours is like mine. Getting it open did rewire cutting thru the case at the base on all four sides, they went out of their way to make it not user serviceable.

The 4x20's blinkers are actually completely controlled by the computer. They don't even have a flasher module!

Update..... I received my service manual today and indeed the flashers and turn signals are controlled through the display cluster(LVA14253) a $438.00 part.

I havent taken it apart again yet but the signals and the hazards have different inputs so its likely the cluster, otherwise I think signals or the hazards one would be working.

Looks like the signals can work and the hazards not and vice versa.

Anyway hopefully this will save someone in the future a lot of time.

Thanks everyone for your help.
