Anyone know how to check whether one is bad? This is on a 67 Cougar with a C4

I bought it, and the guy has a push button rigged up to start the car. The key will not start it. So I am starting troubleshoooting, i was thinking that maybe the switch went bad and that is why the guy jerry rigged it. I also have a new ignition switch that I am installing anyway.

Thanks

Not sure, but I would think with the trans in park or neutral, you should have very low resistance across the terminals. If the resistance is high, there's your problem.

But, I have never checked one out, so there may be a reason that doesn't work.

see if it starts in park or neutral? if it doesnt, replace it.

get rid of that push button start crap to0, totally out of place on a 1967 vehicle

Since this is a new to me car, I want to make sure it is really bad and just start swaping parts when it may be a wire problem.

I just checked mine on my 66 mustang. Looks to be the same switch for your Cougar. There should be 2 connectors from the switch up to the firewall. Mine were red and black. One is for the reverse lights and one for the neutral start. If you put a volt meter across both pins of each and move your shifter to neutral / park (or reverse if you are on the other connector). You should get continuity (zero or little resistance) when the switch is made. If you aren't the switch may need to be adjusted. You will need to loosen the bolts on the side of the transmission for the neutral switch and use a #43 drill bit to align the small hole in the side of the switch (make sure the transmission shifter is in Neutral). If you still don't get good continuity then your switch may be bad. Mine was jsut out of alignment and now will start in Park and Neutral.

Good Luck!

For a quick check, you can also just unplug the connectors and connect a jumper wire across the red and black one (on the ignition switch side of the connector) to make the connection and then try to start it. If it starts with the key, then you know your problem is somewhere between that connector and the neautral switch.

Awesome that was exactly what I was looking for....
