Hey guys!
Was working on replacing the radiator on my 2000 Impala.
Made a dumb move.
Its a tight fit to remove the radiator from its position and out of the underhood housing. As I was attempting to move it out, the radiator cap clipped the positive lead of the vehicles battery. It sparked, and actually the radiator cap welded itself to a metal part of the underhood with the other end of the cap still on the positive lead of the battery.
I managed to unhook the radiator cap from the battery post after about a minute.
My thinking was that surely the main fuse must have blown as the starter would'nt turn over.
I checked all the main fuses and the starter relay. Even switched another like relay to the starter crank relay slot on the underhood junction box.
Still no start. No click, no start!
Let me add that the short at the battery did cause the solenoid at the starter to fry.
I took the starter out and bench tested it. It spun but the cog that engages the flywheel did'nt come out to engage, so I bought a new starter and have it allready installed.
Here's the lowdown. The purple solenoid wire that should carry 12 volts when you turn the key to start, is'nt reading any voltage when turning the key.
All the fuses and relays test fine.
There's a crank fuse inside the car in the fusebox, that is showing 12 volts when I turn the key to start.
What am I missing here?
Why no voltage in the solenoid wire at the starter???
What must have happened during the short circuit at the positive battery post to cause voltage not reaching the purple solenoid wire now?
Btw, if I apply 12 volts manually to the solenoid at the starter, the engine will start right up and die after 2 or 3 seconds.
HELP!!!
Update........ This is my dad's car, and he did'nt tell me that he has to hold the accelerator down some in order to prevent the car from stalling.
So the engine does start right up if I apply 12 volts manually to the starter solenoid.
What I have to figure out now is why 12 volts is'nt reaching the purple solenoid wire that should energize when I turn the key to start.
