89YJ auto 4.2L weber and nutter done
OK, we did the following: weber conversion, nutter bypass, new rad and
hoses, new vac hoses. new hall effect pickup in the dist, new thermost vac
switch and it idles GREAT, idles like no tomorrow, starts right up. Problem
is that as soon as you put it into gear it shuts off. We traced it down to
the neutral safety switch and jumpered it so that it now runs but from the
diagrams we have in the chiltons I just have one questions 'HOW THE HECK
does that NSS affect it when going into D/R/L My guess is the switch is bad
unless there is some kind of relay involved somewhere.
Any suggestions ??? Hate to just throw a NSS if not needed, any way to test
it other than the jumper I did ??
And tonight the directionals stopped working, sheesh
TIA

Re: 89YJ auto 4.2L weber and nutter done
Here is a diagram of how to test the switch on the auto transmission...
http://www.optikadesign.net/jeep/89_...ion_switch.gif
Use an ohmmeter to check continuity between each terminal in different
shifter positions. From the electric plans in the Mitchell manual the
Park/Neutral switch should only prevent the starter from turning, it's
connected to a starter Relay cutting off the path between the the ignition
switch and the starter solenoid.
The transmission seems to be sending other signals as you will see for other
shifter positions (R-D-2-1), but I'm not sure where these signals end up. I
could not locate these signals via the wiring diagrams of the MCU for the
4.2L nor the ECU of the 2.5L. I'll keep checking if I find where they go or
maybe someone else has the service manual and could find out, the Mitchell
doesn't indicate anything!

Re: 89YJ auto 4.2L weber and nutter done
Thanks, I'll look it over but that switch terminal does not look anything
like the one we have. The one on mine is flat and wide and only uses 3 or 4
wires. It might be different inside but I'll find out when I drop the pan.
Need to helicoil one of the corners thats stripped out and missing a bolt.
Even the snap-on shopkey does not have anything in it for this.
One of the things we are curious about is the two relays next to the
battery and what they do and if they are involved somehow. Might just
pickup two new relays along with the NSS. Heck with all the new stuff I've
put in it the past 3 weeks I might as well. For sure I need to clean out
those sockets judging by the look of all the dirt around them even though
the contacts looked pretty clean.
This is the first auto I've ever really delt with, I've always owned
manuals my whole life cept for a 75/76 dodge van I bought way long ago.
