Ignition switch starter wire
What exactly does it do to the starter?
My car has up and decided it wont crank and I dont feel like dealing with it. (It's not VATS) I'd rather just bypass the whole thing and have a pushbutton start but Im not sure what to wire to the starter. Does it complete the circuit to ground or apply 12v or what?

Re: Ignition switch starter wire
thats what happen to mine my ignition went out and didnt wanna crank over so what i did was....just run the negative from the starter and get ur power from the fuse box and it should start right up...just use a test light to see what is power and what is negative....and run a wire from the radio fuse to the switch and connect the negative

Re: Ignition switch starter wire
Im not quite sure I follow what you're saying? The negative Im going to assume is the small purple wire by itself that goes to the ignition switch. I need to connect that to the fuse box, but you said to connect it to a negative... I think. Thats simple enough, but what's the deal with the wire friom the radio fuse? What's that supposed to do?
Also, I've been looking at this diagram since Im tired of my heatsoak issues also.
If I ran the wire straight from that positive terminal on the remote solenoid to a push button start and then to the S terminal, would I have problems turning the car off? The key switch is still in control of the ignition, right?

Re: Ignition switch starter wire
You shouldn't have to resort to a remote solenoid. If you're starter is suffering from heat soak, it's likely just near the end of its life. A much better solution is to install a later style starter from an LT1. If funds are an issue a replacement starter to match existing is around $50. If funds are extremely low a replacement set of brushes for your starter runs around $3.
If the issue is the power going to the solenoid the ignition switch is the most likely culprit. If the switch is going bad, bypassing the starter solenoid power from it isn't a good fix. This switch also controls the power to the fuse panel under the dash. If it's bad to the ignition then it's likely bad, or going bad, to the panel.
When it doesn't want to crank-no click, no turn, nothing-run a jumper wire to the S terminal on the starter. Jump this wire to the positive terminal. IF your battery is GOOD the starter should turn over. If it spins with it jumped out you'll know the problem is in the ignition circuit to the S terminal. If it doesn't (and you know the battery and the positive cable to the starter motor is good-starter getting 12+ volts) then you'll know the starter itself is bad.

Re: Ignition switch starter wire
well on mine i ran it to the fuse box to get the power...and the car only starts when the key is turned in the on position cause it only has power when the power to that fuse is on....or u can just run both power and negative from starter into the car.....and put them to the push button and do it that way...but i did it with the fuse so it only starts if the key is in the on position..

Re: Ignition switch starter wire
no cranking can me a couple other things, such as a bad starter or a locked engine, test for power at the S terminal when the key is turned to start,

Re: Ignition switch starter wire
If you have the radio fuse hooked up to negative ;every time you push the switch,the fuse would blow because it is a direct short to ground
Test it ;Put a wire on the batt neg terminal and touch to frame?
Then try it with the pos terminal and see what happens; sparks
Negative terminal is DEAD unless someone has put battery in backwards
