1985 FJ60 4WD indicator light in flip mode (1 Viewer)

[GunDriver]

Hi everyone-
I recently bought Landcruiser #2 and while driving it around on the maiden voyage I noticed that 4WD indicator light would not come on when in 4WD. I figured I'd check to see if the switch was plugged in on the transfer case and sure enough it wasn't. So I plugged it in and was getting back in to drive to the beer store to celebrate how smart I am when I noticed that upon turning the key to ON the 4WD light lit right up. I verified the transfer case was in 2H and got under the vehicle and verified the forward drive shaft was turning (it was). So for fun I shifted into 4H...and the 4WD indicator light turned off. I got back under the vehicle and confirmed it was in 4WD because the forward drive shaft would not turn by hand. So the green 4WD indicator light is on when in 2H, and goes off when shifted into 4H or 4L (makes perfect sense.). I checked transfer case fluid level and it is right at the bottom of the fill port. I pulled the switch from the transfer case and actuated it by hand while hooked up- 4WD light was coming on with pressure applied, light would go off when pressure released.
I am not sure if that is proper function, but am I missing something?

sounds like something's hooked up backwards...I take it you got a 62. Can the switch be installed two ways? what happens if you switch the lines? I'm a 60 guy so I don't know the system to well, hope you get it figured out

I am a 60 guy also- this is the pressure actuated switch that screws into the side of the transfer case for 4wd indication only- pretty strange. The electrical connector has a slot that only allows you to hook it up one way, so even I shouldn't have been able to connect it wrong...should be pretty simple fix, I'm just not seeing it!

oh weird...well I guess I'm no help here then. Good luck to you sir!

I will preface this with the fact that I am NOT that knowledgeable about the FJ60/62 wiring, but I can read a schematic.
Looking at the schematics I have: The t-case 4WD indicator light switch is a simple, normally OPEN, single pole, single throw switch. One end connects to the 4WD light the other to ground. Shift into 4WD and the switch closes lighting the 4WD light.

If your switch is working backwards the only possible explanation is that the switch in your t-case is a normally CLOSED switch which would work exactly as you described. If you can source a different switch it may fix your problem.

I appreciate you going through the 60 schematics for me. I had been attacking this problem with the assumption that the switch was a normally open one correct for the application. I am wondering if maybe the reverse indicator switch is normally closed and my cruiser got two of them installed....anyway I will see about another switch and will update if it does the job. Thanks again for your help.

Stumbled upon this and am now interested in the outcome. Did you ever find out what the issue was ?

Maybe check to see if the vacuum lines are switched on the red and blue vacuum switches. They should be mounted on the engine firewall, if I remember correctly.
