broncoII electrical prob. 4x4
I have just bought a '87 bronco II, standing still i switched it to 4X4 a few times and it made a noise and went to 4X4 so i pressed low range and it just flashed so turned off went out the next day and the 4X4 light was on and the low range was flashing and it wont stop or come out of 4X4 what seems to be the problem and can i put a shifter on it to replace the electric silonoid? some one please!

I don't believe you can put a manual shifter on the electric shift case. You would have to get the manual shift case and shifter and whatever other parts you would need, basically a donor vehicle would be good. As far as the transfer case not disengaging, you might try getting it to shift out while in neutral and then park, try backing up and then push the shift button. Yoiu can get underneath the vehicle while someone is inside holding the BRAKE! while it is running in neutral and try tapping on the electric motor on the back of the transfer case, it may shift then. These electric shift motors seem to mess up quite often, there is a good thread on this site on how to take it off and clean it up, just do a search for it. The clicking noise you hear is a relay located in the upper top right hand corner of the dash, on top there is an access panel, there are some tests to see if this box is working properly, I can't remember where i saw them, probably on this site. Ther is a wealth of information on here just search for it.

Probably the shift motor is stuck in some way. There are a few articles on the net about cleaning/rebuilding the shift motor. Try putting "Ford transfer case shift motor" into your favorite search engine.
Not directly. You end up swapping the entire transfer case. The manual shift BW 13-50 was fairly common from that era, so I wouldn't expect it to be too hard to find.

I would have to agree with the two previous posts - I believe there is also a microswitch assembly or some such that gives the indication. Part of what could be going on is this switch assembly might be misaligned, etc. Could also have some binding inside the t-case. Best thing to do is to pull the shift motor off and do a thorough clean-up and re-lube on the pieces and parts that need it and test everything while it's apart. The electric shift motor / t-cases are a known issue and require regular maintenance and check-up. They are not a 'fix-and-forget' thing. If they are maintained, they work fairly well, just like the manual shift models. If your BII has automatic hubs, though, I'd consider getting rid of them - if you keep them, they are also another 'must keep up with maintenance on' item. But, be aware that they are known to break regardless of how well you keep up on them.
I can't remember if there is a write-up in the Tech section of this forum or a post somewhere in here or what, but I do recall seeing the electric shift motor issue come up several times on this forum and others I am on. I believe there is also a how-to over on TRS in their tech library. Hope this helps and happy hunting!

thank you all on the topic replys i had done additional research after the post and fond that i could take it of and manually turn it then had to realign the gear inside i found out that it is the selecter switch on the back of the motor that tells the position of it, that is the part that is bad i put it all back together and can easily shift from 2 high to 4 high but messed up again going to 4 low

I can't remember if that all comes as one unit or not - but you can probably fix the switch(es) that give the indication and feeback to the control module. You'll also want to clean up the shift motor assembly and re-lube the gear drive, etc. You can always check the local junk yards and car-part.com for manual shift t-cases to swap in if you'd rather go that route.
