Bypassing neutral saftey switch?
I have a 91 Cherokee with 200k+ miles on her and a worn out NSS. A new
one will set me back $200 and the Jeep is only worth about $1000 or so. I have cleaned the NSS twice and the last time only lasted 2 weeks before it quit again. I would like to bypass this switch, so that I can drive it, shile I search for a replacement. Does anyone know of a way to bypass the NSS? Thanks, Sam |

Bypassing neutral saftey switch?
Are you driving an automatic or a standard?

Bypassing neutral saftey switch?
I had an old GMC motorhome that did this. The switch has developed a bit of
internal resistance so that it can't carry the current that is required of it. You put a continuity tester on it and looks fine, a real head scratcher. You can make a jumper out of the same type of terminals that are on the switch and a piece of wire. A real sophisticated repair is to wire in a relay actuated by the switch. If the switch is not carrying as much current, it won't burn up the contacts as fast. $200 for a neutral safety switch? Have you checked aftermarket suppliers?

It's an automatic. I just went out an cleaned the contacts again and
it still would not fire up. I'd like to cut the wires and totally bypass the switch. I'm going to retire it as soon as I find a replacement vehicle.

The cheapest I found was $183 + tax at AutoZone. And then there's the
hassle of unplugging it from the wiring harness on top of the bell housing. Don't really want to go down that path. Sam Earle Horton wrote: > I had an old GMC motorhome that did this.

Bypassing neutral saftey switch?
That's what I did on the motor home. It worked great, but you will have to
pay attention because you can start it in reverse or drive. The problem with many of these designs is that they put too much current through the neutral safety switch, so it eventually burns out. I have seen other vehicles with a relay, where the switch lasts forever, but the relay burns out instead. ;^) Earle > wrote in message oups.com... > It's an automatic.

My trusty '77 Cherokee has been that way for the 20 years I've owned it. The tranny overhaul about 9 years ago didn't change a thing. It's no problem. It also means that you can use the starter (with the tranny in gear) to move the Jeep from a bad spot in case of a stall/no start (like off a railroad track). But, if you do, the starter will have to be repaired in very soon.

I found something in the Haynes manual (Cherokee 1984-2000, page 7B-5)
that might be helpful. It is for the 4 speed auto trans. It appears that everything transmission related goes through that switch, not just neutral/park and back up. The wiring diagrams use numbers instead of these letters so it was no help. X E F G H D C B A The X shows the locking tab P B-C R A-E N B-C D (blank) 3 A-G 1-2 A-H If this problem happened to me, I would disconnect the connector and jumper the wires. But you won't have backup lights and you should stay in D so you don't confuse the computer. Or trace the B and C wires to an accessable location and strip the wires enough to install a jumper and switch to see if that will work. Just be sure to put some liquid electrical tape on the bare wires. When my ignition switch melted in the middle of winter, I put a jumper on the solenoid and a heavy duty switch on the dash. I replaced the ignition switch when the weather got nicer, but I still use the dash mounted switch so I won't have the problem again. The starter sucks a lot of amps and it only takes a poor connection to quickly melt the connector, transmission switch or wires.
