1985 chevy k10 350. Just wired the truck up with the painless wiring kit got the truck started and could not get the starter to disengage unless I unplugged the negative battery term. After some researching i realized i had to adjust the slider on my ignition switch but as soon as i went to start it my starter started smoking. I took it to get tested they said the starter was fine then plugged it back into the truck and it will not start. My lights dim when i got to start it but i get nothing from my starter. I used a test light to test the voltage to my purple wire and it's doing what it's supposed to and i'm getting 12v from (battery to starter) wire. I'm stuck and i feel stupid because it's such a simple system please help.

 

Welcome from Florida. Start from scratch and redo the wiring. Sounds like there is a mistake somewhere in the wiring.
