Re: Brand new '89 YJ
If the engine will fire off with the starter engaged but then dies with
no spark when you release the key points to a problem with the coil
resistance wire. The coil is fed full 12 volts when starting, a few less
volts while running. Check by turing on the ignition, see if you have 12
volts at one or both of the coil terminals, if voltage then you have a
different problem. If no voltage, try it with the starter engaged, if
voltage, you have a bad ignition switch or bad resistor wire.

Re: Brand new '89 YJ
The 2wd-4wd shifting and the hi range/lo range shifting are independent
things inside the transfercase. the only place they connect is that both
functions are on the transfer case main shaft (hi/lo in front), 2wd/4wd
in the back part, and the shift linkage does both depending on where it
is in the shift pattern. So your problem could well be inside the
transfer case.
My take from the pictures is that the shift linkage is coming apart when
you shift to low range, this could point to a bad transfer case mount
letting it slide around or perhaps something jamming inside the transfer
case and causing the engine/trnanny/trnasfercase to shift.

Re: Brand new '89 YJ
The 2wd-4wd shifting and the hi range/lo range shifting are independent
things inside the transfercase. the only place they connect is that both
functions are on the transfer case main shaft (hi/lo in front), 2wd/4wd
in the back part, and the shift linkage does both depending on where it
is in the shift pattern. So your problem could well be inside the
transfer case.
My take from the pictures is that the shift linkage is coming apart when
you shift to low range, this could point to a bad transfer case mount
letting it slide around or perhaps something jamming inside the transfer
case and causing the engine/trnanny/trnasfercase to shift.

Re: Brand new '89 YJ
To the positive side. I don't know for sure which color that is on the
YJ. Yellow maybe?
The connection 'should' should continuity on a meter from that side post
on the solenoid to the correct wire. You can even open the harness and
trace it.
