Getting it road worthy. Whats wrong with the carb.

[Slow Left]

View attachment 951767 Looking at the second row of relays(which is what these two are on) i have 4 places for relays.

Do you have two rows of relays, with each row containing 4 relays?
Or do you have two rows of relays, with one row containing 3 relays and the other row containing 4 relays?

In the image you posted above, is the green box the Turn Signal Flasher that you replaced?

And then is the empty relay site with the red arrow pointing to it in the same row as that green box or does the green box belong to the other row (the one I can't quite make out in the image)?

 

[LAgallegos]

okay. a lot of questions. I feel like a lot of them would be answer by a picture.

Brown is towards the front of the car.
the biggest black square relay is the turn signal relay I replaced.

According to the FSM, this is where the relays should be.

You can confirm that those relays correspond with those circuits by seeing if the circuit works with and without the relay installed...

...or, if it is the OE fuse, you could pull it and run the part number on it to confirm that it is the correct one for that circuit...

The 'Cooling Fan' relay corresponds to the fan in the engine bay (it looks kinda like a hair drier and is located on the DS fender near the brake booster). When you turn the engine off (after it has reached operating temperature), you should hear the Cooling Fan kick on...it sucks cool outside air in through the vent on the DS front fender and blows it over the manifolds. If you have never heard it kick on, then it might be missing a relay...and there might be other issues with the circuit...it uses the 'Dome' main fuse, sharing the fuse with the dome light that should turn on when you open the doors...

If you look at the wiring diagram, you will see that all the Tail Lights, License Plate Lights and Side Marker Lights are behind the Tail Light Control Relay.

On my rig, the Tail Light Control Relay has the same part number as the Light Control Relay (Relay for headlights...which run off a different fusible link).

Light Control Relay (3 prong)
TEQ PN - 90987-01003
ND? PN - 056700-4800

Tail Light Relay (3 prong)
TEQ PN - 90987-01003
ND? PN - 056700-4800

So if you move the Light Control Relay to the Tail Light Control slot, you should notice that your headlights no longer work, but your Tail Lights (I think this is what you call 'Running' Lights), Side Marker Lights and License Plate lights should work...

Thank you so much. That helps a lot.
The only problem I see is that the slot that you labeled as the taillight relay is a four prong. Not a 3....

and I've never heard the cooling fan kick on. I figured that was one of the missing relays. Its been cold enough here haven't really needed it though.

Hmmm...is there any way you can chase down that part and part number for your year FJ60 (it is possible that the FSM is wrong or incomplete) either in person at your local Toyota dealer or PM Beno to see if he can confirm that it is indeed the Tail Light Relay and has 4 prongs?

On the Cooling Fan Relay, double check the numbers I gave you for the relays on my rig to see if you have one on your relay block that you can temporarily swap in there to see if the fan kicks on. Just a heads up, there are other components in the Cooling Fan circuit that must also be functioning properly, so even if you swap in a good relay and it doesn't work, it just means that you have to confirm that those components are working correctly, too.
Those components include: sensor (on exhaust manifold), fuse and Cooling Fan 'Computer'

Yeah I got no clue. I'll do some digging though and see what i can find.

 

[FJ40Jim]

BTW, the clutch MC needs replacing. It's leaking pretty good, and can quit working any day now.

Just read through this thread, and @CardinalFJ60 says that the Cooling Fan Relay on his '87 FJ60 is located behind the kick panel in the DS wheel well...not in that Relay Block.

See:
https://forum.ih8mud.com/threads/fj62-dome-light-circuit-parasitic-draw.821030/#post-9405837

Toyota must have changed some Relay locations/parts after publishing the initial FJ60 manual in 1980...

...the question is, how are you going to identify which Relay goes where for your year FJ60 and what it's part number is (if it is missing from your rig)...

 

[LAgallegos]

ah, okay. Well guess I'll have fun figuring that out...
On the bright side, I finally got tires!

It looks like there was a Supplement to the Chassis-Body FSM published in April 1985...I wonder if that might have any updates on the Relays for you...now you've just got to find a .pdf copy...

• 1981 – 1987 2F Engine, Pub. No. 36104E
• 1983 Land Cruiser Electrical Wiring Diagram, Pub. No. EWD36679A
• 1985 Maintenance Procedures, Pub. No. 36788A
• 1981 2F Engine Emission Control Repair Manual, Pub. No. RM36043
• April 1985 Land Cruiser Repair Manual Supplement for Chassis & Body, Pub. No. 36274A
• 1984 Land Cruiser (Heavy Duty) Repair Manual for Chassis & Body, Pub. No. 36262E

see post #5 in the following thread:

https://forum.ih8mud.com/threads/land-cruiser-fsm-1984-repair-manual.214060/

@2mbb might be able to provide specific information about Relay locations and part numbers....it appears that this Supplement does include updates on the wiring diagram from 1985 on...


See this thread:
https://forum.ih8mud.com/threads/complete-factory-service-manual-set.391712/
He had the April 1985 Supplement (Pub. No. 36274A) back in 2010...
...maybe he still wants to sell it?
...or it would appear that either Toyota or Spector Off Road also sell a hardcopy if you can't find it online

 

[LAgallegos]

contacted beno and he said it was the same all through fj60 production...

Light Control Relay (3 prong)
TEQ PN - 90987-01003
ND? PN - 056700-4800

Tail Light Relay (3 prong)
TEQ PN - 90987-01003
ND? PN - 056700-4800

question on this... what is the difference between the TEQ PN and the ND? PN ?

I don't know what the difference is...so I wrote them both down. I'm not even sure if I am calling the ND part number correctly (in other words, I don't know what ND means or if what I was reading on the part was actually a 'N' and a 'D'...that's why I put the question mark behind it...to signify my uncertainty).
I believe TEQ is the original Toyota OEM designation (in Japanese?).

So Beno says those part numbers are all the same for all years FJ60s, then either that Tail Light Relay is located in a different place on your year FJ60 or the wiring of the circuit(s) is different...which leads you back to getting ahold of a copy of that Supplement to see what (if any) changes were made...

 

[LAgallegos]

okay. so interesting thing. im looking at my relays and i find this one. towards the back. and its labeled 90987-02006 (note the six)
so none of the ones you listed have the 02006. I replaced the turn so i know its not that. you didn't list the wipers so i thought It might be that. But i tried the wipers and they still worked.... so what is it for!?

 

[gregnash]

Doing a little search-fu turns up that the relay seems to be either a blower motor or headlight relay. Fits on LCs from 1981-2004 from what I can find and does a variety of things in those years. For your reference, if you have the part number Toyotapartzone.com is a great little tool to help determine things, even buy parts...

 

[micruz60]

Those supplements to the FSM would be really nice to have..... I have been stymied by the 1980 chassis wiring diagram not helping...
ND is 'nippondenso' sorta equal to oem TEQ
Awhile ago I had a similar issue with taillight / reverse lights and chased all the grounds. Turns out the wiring behind the left rear cargo area (by the jack and rear washer bag) was severely corroded along with the trailer hitch wiring loom... this may be what is causing your problems. Another good thing to do is to remove the door sill at the drivers door, and clear out any crap that may have compromised the wiring run thru that area, along with removing the kick panel at the side of the footwell, just to confirm that carb cooling fan computer is intact, also verify that the under hood wiring to the bottom of your exhaust manifold is intact, plenty of threads on that subject.

So I've chased down the wiring and looked behind the kick panel on the DS and the panel before the DS rear tail. All the wiring looks great. Looks pretty stock for all the lighting. but anyway. I can't really get access to the wiring where it passes by the doors cause of this -

and all the screws on all four doors look like that. Any good way to get em out?

 

[LAgallegos]

I also found a drain hole on the bottom of the Gtank a little past the spare tire. I'm thinking I might drain the tank and see what I can get out that way. The spare tire is playing a pain to get off.

 

[micruz60]

You will need to spray and let soak those screws with penetrating oil, same with sparetire crank... They can be a pita, deflate your spare to help break it free / work chain both directions

[gregnash]

What Micruz said. Lots and lots of PBBlaster is what you need. If the screws get truly ripped up then you might need to get one of those backout tools.
