Title: Tilt away neutural saftey switch
Post by: Tomdeg on May 30, 2024, 02:43:15 PM
Did the 4 speed cars have a NSS? I'm able to start the car with the steering wheel in the tilt away position.Just curious
Thanks,
Tom

Thanks Jeff. So being able to start the car with the wheel away is normal?

Its not normal, more than likely someone has bypassed your tilt wiring or modified it

Steering wheel (tilt) position and what gear the transmission is in when trying to start are two different things

Looks like you need to trouble shoot and investigate the tilt related wiring

There is small switch inside the vacuum motor of the tilt components that should be preventing the car from starting unless the column is straight

Thanks, guys.
Yes, I noticed the vacuum motor has a plug with wires but couldn't see where it would plug into.

It should plug into the identical plug on the harness or the car will not start. Probably someone did not know how to adjust the vacuum motor so they bypassed it.

Was under the dash yesterday and for the life of me, I couldn't find anything that the motor would plug in to. Would it have been a mini harness that would interrupt the wiring from the ignition switch? Does anyone have a picture? Also, the wheel will tilt away when the engine is running and the door opens. Could that also be because the wiring for the motor is bypassed?

Thanks,
Tom

Yes and yes

In 1968 there is a tilt steering harness

Is there wiring connected to the underdash components?

Everything is connected except the wires for the vacuum motor. It tilts away when the door opens.

The switch inside the vacuum motor should be telling the car to start or not. If its bypassed the car will start.

So it looks like I may be missing the small harness. Any idea where to get one?
Title: Re: Tilt away neutural saftey switch

There is no "small" harness.

The tilt harness has provisions for the vacuum motor, relay and solenoidp

So after a little more investigating, I found a small jumper wire going to the ignition switch. I checked the vacuum motor with an ohmmeter and the circuit was open when the wheel is in driving position. I'm assuming in that position the circuit should be closed. Is there a way to repair or clean the contacts or does it need to be replaced?

That small switch in the vacuum
can be cleaned.

Remove the vacuum motor

Untwist the canister to open it

Remove the switch by grinding the rivets

There will be several small parts and two springs that come out

Clean everything and reassemble

You can use two small screws to replace the rivets

Or send it to me and I will see if I can get it working

😉

Thanks for the great info. I may take you up on your offer. I bought the car in January. It had been sitting since 2010 so it's taken me a while to bring it out of hibernation, (everything leaked). I'm going to enjoy driving it for a while before fixing more stuff.
Happy 4th,
Tom
