No ignition power

Hello guys was wondering if anybody can help me diagnose what's wrong with my car. I have a 92 Camaro 5.0 tbi 5 spd. I seem to be getting no power when I turn my ignition at all I do get some power to acc like head lights and dome lignt . I've re did ground checked battery and everything seems to be good . I do have power to my starter at solenoid terminal but none seems to be getting to the ignition switch . And no power seems to be leaving stater solenoid ?

Re: No ignition power

Any help guys would a bad starter stop the ignition switch from getting any power. Or just fusible link

From what you describe , your possible suspects would be either a fusable link or the ignition switch , the starter itself would not cause you to have no power at the key (unless all the wires were taken off of the big terminal , and I'm sure those are connected , right ?)

PS , if a fusable link IS bad , it's usually bad for the reason that a short circuit took it out . A look around the harnesses would be in order to see if any are pinched or otherwise shorted , also especially check any "hacked in" radio / amp / etc aftermarket parts cause those are a prime location for wiring faults that blow fuses (and fusable links sometimes , too)

Good Luck with it ...

Re: No ignition power

Ok thanks for the reply I did replace my fuisble links when I connected the battery it blew again I'm not sure if it was because it was a bad wiring job just wanted to see if I could get any power to the ignition switch . I will try soddering a new fusible link tomorrow . If it blows again must mean a short in my ignition ? I've already replaced my ignition switch so I'm guessing it has to be my fusible link

If it already blew two fusable links , the original and the one you already replaced , then yes , you do have a short circuit somewhere . That somewhere is not all that likely to be the ignition switch itself , It's far more likely to be a wiring fault where a wire is touching ground somewhere or a device itself being short circuited . For instance , you say it blows the link the instant the battery is connected ? That could be the alternator shorted at it's output terminal (just as well as it could be shorted wiring) . The way you'd isolate this would be to unhook (and fully charge) the battery . Replace the bad fusable links . Hook a headlight bulb in line between the car's + terminal wire and the battery . Hook the battery's negative up as normal . With the headlight bulb in series with the + battery terminal and it's wire , the bulb will be lighting brightly . Now start disconnecting things from the line till the bulb goes dim (or out completely) . That will be your shorted part . Say it was that when you took the big wire off the alternator the light went dim , that would mean your alternator is shorted . You'd do best to search up a wiring diagram for your car and use that to decide where you want to start disconnecting stuff to find your short . For instance, the aux terminal block near the radiator is a good place to disconnect to begin to isolate circuits . Just don't forget to REALLY inspect every inch of the wiring harnesses for areas rubbed clean of insulation and shorting to the body somewhere .

You do have a short , now all you gotta do is go find it .....

Good Luck

Re: No ignition power

Wow thanks for the great response. Nice trick so Could my starter be shorted ? Solenoid looks kinda burnt ? Where would I wire the bulb
