I've read 30+ threads on NSS repair and I'm stumped...
Ok so I was having problems with the XJ starting from time to time (would start by wiggling the shifter) and no back up lights so I figured it was time to clean the neutral safety switch (NSS).
Armed with multiple writeups and a confident attitude I proceeded to start the process of removing the NSS and promptly broke the housing getting it off. Undeterred I planned epoxying the broken part of the housing. Trying to undo the screws I stripped two of them off so out came the dremel to cut the screws off so I could split the NSS casing in half. Alternating cutting and spraying the work area with WD-40 (to dissipate the heat into the lubricant) I was able to open the casing and clean the internals. I drilled out the bad screws and replaced everything with bolts. I then put the switch back on the Jeep. Finally I had back up lights, but the Jeep wouldn't start in either park or neutral...
Assuming that either breaking the casing or heating up the internals by cutting off the screws had damaged the switch I decided to order a new one.
New unit arrived in the mail and I set about installing it into the Jeep. Install was a cinch and I had reverse lights once again. But I still can't start the Jeep... :bawl:
I've had a helper sitting in the seat trying to start it as I rotate the unit to find the correct adjustment to no effect. The Jeep won't start anywhere in the adjustment range. Also, when in reverse the back up lights stay on the entire way through the adjustment range. Just like when I was having problems with the NSS acting up before, the dash lights and radio go dead when turned to the start position.
I have checked the following:
NSS (obviously)
Starter Relay (Swapped with known functional relay)
Starter Fuse (30amp in PDC)
Battery Cable Connections
My questions are these:
Is there more adjustment than just the few degrees that I can get with the top bolt in place on the NSS?
I remember seeing a diagram about the plug pins to check with a multimeter but the only one I can find at the moment is for the pre 97 xj's. Does anyone have the newer pin diagram?
What ideas do any of you have to solve this?
PS: No I don't have an FSM so I'm working entirely off of forums and internet writeups on this one...
