Gentlemen,
Last Sunday, I took my old 1984 XJ out for some wheeling and I noticed that the 4WD light would turn off, when accelerating full-throttle.
Let me add a couple of details. When I got the truck, I removed all the emission control devices, except the catalytic converter. I also changed the carb with a Weber one. I therefore removed several pieces of tubing, but I made sure that the vacuum tube which goes to the transfer case remained connected to its original position on the intake manifold. Original, in this case, should be read "where I found it connected", not where it should be connected.
Now, I should assume that the 4WD goes off, because under full throttle, there is no vacuum? Maybe the vacuum pipe should be connected to the vacuum canisters (there are two of them in the truck, on the passenger fender)? I do not care that much about the light itself, obviously, what I care about is the truck shifting out of 4WD when I need it in 4WD.
Any advise would be greatly appreciated.
