No Power from Starter out- - - Any Ideas - help !

[Draginwagon]

Went to start my 454, and NaDa. No Power at all, No interior lights, nothing. Checked the battery, and it's fine. Check connections all seem fine. 12 volts going to the starter, Ok. Nothing coming out of Starter. No power at all.
installed NEW Starter. Same thing. 12 volts going in, and Nothing coming out. No power at all.
I am cleaning the ground connections on the car as we speak.
hoping that is the issue. But it is a Clean and detailed engine compartment.
Any Ideas???? Any help greatly appreciated.
Thanks

If the ground cable goes to the alternator bracket, check the bracket mounts too. I've seen them have all three attachment points corroded and rusty. Makes diagnosis hard to do. May be easier to just move the ground cable.

Thanks,
There is a grond to the block and the radiator support. The support is powder coated and might not be making a great connection. And I think your right, rust could have formed behind the ground on the block.
I'll give it a try.
Thanks

Cleaned and checked all the grounds, and still no power coming from New Starter motor and solenoid.
Checking every wire and connection.
12 plus volts before the starter, nothing coming out. Don't know why. http://www.yenko.net/ubbthreads/images/graemlins/frown.gif

What do you mean power coming out of the starter? Does this car use a junction block on the firewall to distribute power to the ignition switch?

check the 10? guage wire junction block behind the battery on the rad support.

Sorry, junction block on the core support is what I meant. That is the most common cause of the situation you are describing.

Power does not come out of the starter. Where your positive cable bolts to the starter there is another large, probably 10 guage wire that probably goes to the junction block mentioned behind the battery.In essence, the wire simply takes it's power for the car from the positive battery cable.

Thanks Guys,
The junction block from the positive terminal that is under the passenger side fender was the issue, couldn't see the Broken wire. My wife traced it with the schematics and found the problem.
Back runnin' Like a Bear Now.
Thanks again for everyones help.
