Vette(s): Little on the rough side right now, with new paint and new interior it will be looking fine!
even if i had a paper clip handy (strange i don't since i became a paper pusher) i don't know where to connect it to bypass the NSS, i'll probably just do body work untill the new NSS gets in and PRAY that it will fix the problem, otherwise i have no idea what i will do....  :(



I hope to one day be as knowledgeable as most the guys on here... but till then I'll have to just keep asking the questions with the obvious answers....

Ok..paperclip is one of the most useful tools to have with old cars..can fix a whole bunch of stuff with them..except a fuse!! All you have to do is unplug the NSS and put the paperclip in the connection ..it's really that simple..it's just a ground so no worries of a spark.

Okay so i tried the paperclip idea, and it did nothing for one of the two connections i put it to and tried, the other one instantly heated the paperclip glowing red when i turned the key, there is a third connection on the old NSS but i can't see anywhere that it would connect to... and i still can't get any life out of the starter...

Ok..that's good..the one connection that got hot had a load on it that's why it got hot..can you remember where that one was?? If you did the one connection that was for the NSS and it did nothing means the switch is ok..do you have power on the single wire on the starter with the key in the start position? Kinda hard to get to but an alligator clip on a test light will let you know fast..it's only with the key in the start position though..try that and see what you have...I know you said it's a new starter but it's not unheard of to get a bad one.

Which single wire on the start?  and this is my second new starter in a week, i don't think they both could have been bad.  Here is a pic of my NSS (new one gets in tomorrow) 

The red arrow is pointing to the plug that was hot, the yellow arrow is pointing to the plug that did nothing with the paperclip in it, and the blue arrow is pointing to the plug that i can't find the end where it used to go into.

Your wires should be for Starter Purple to Purple/White for Backup lights Pink/wht to Lt Green
 
You need to be carefull it sounds like you put power streight to grnd for the clip to get hot if you jumpered the right pins for the starter and that clip got hot that would meen thir is a short in the purple wire going to the starter, which would burn out your nuetral safty sw.
 
On the 75 wire diagram it shows near the strter that their is a seat belt reset relay, when you go to the second page it is not their, not sue what that means if it is suppose to be their

Ok..is there any way that this switch is not adjusted to neutral? Yeah 2 starters would be rare to have bad..the wire on the solenoid by itself closest to the engine should be the one you need for start power to energize the solenoid..I believe there 2-3 small wires on the opposite side..have to have the NSS in to get that to work so maybe wait until the new one comes..

I have tested the small wire on the engine side of the starter and it is getting power when the key is turned...  And what should i do to find the short in the system that would let that paperclip get that hot?

Ah HA!!! Bob hit on something there....early '75s still had the seatbelt interlock system, which will not let the starter engage unless the seatbelt is fastened. But...it has to be done in sequence. First, you have to sit in the seat, then fasten the seatbelt. If the system is still on the car, it will NOT start unless you follow this protocol.
Give that a try, and see if it works.

Just tried it, didn't work.  That was actually the first time i have ever had the seatbelt on in that car so i'm pretty sure that system was disabled a while ago.
