no juice&need to turn the motor over

Just wanted your guys opinion my g-body has been setting for 2 years&I'm getting ready to go@ it to finish it up&the battery which was new when I parked it seems to of went bad.
I put it in the car&let it sit on the charger allnite &all I can get is the lights to come on while still on the charger when I go to fire it nada.I pull it off the charger&have nothing.So I'm pretty sure the battery has went bad I'm taking it to parts store tomorrow..anyways do you think hooking up jumpers will be enough to crank it?
I just wanna make sure it hasn't locked up .I doubt if has it's been stored indoors.Hope all is well

You can always try and jump it, but even if it starts, the alt wasn't designed to handle the entire load of the veh electrical system, it needs that good batt as a buffer, so don't let it run too long with out a good battery.

Turn it over by hand...that will tell you if it is seized or not.

Kid,
I'm with poncho62. I've seen the 305 I pulled out of my Monte lock up while sitting in the garage of the guy I gave it to(2yrs+/-). It was a perfectly good engine when it was removed from car. He didn't remove the plugs and spray in some WD40, or oil, or turn it over, or anything. He installed it into a car a little later and it wouldn't turn over, locked-up, and he insisted that I gave him a bad engine, True story, no BS.
I hope yours isn't locked-up. Better to try turning it over by hand, and break it loose(if it is locked-up) than to use the starter to do it. It could break the starter or the block.
I wouldn't use the balancer bolt to turn it over as it will more than likely break the bolt. I would prime it with oil priming tool that simulates the distributor in the block.
Get a couple of 3/8-24 bolts about 3" long along with the same size hex nuts and washers. Remove the crank pulley after loosening the belts(alt, AC, pwr steering). Install the hex nut/washers onto the bolt about 3/4" from the end of the bolt. Thread them into the balancer accross from the center of each other where the pulley bolts were about 3/4" deep, and tighten the hex nuts/washers onto blalancer while holding the head of the bolt with another wrench to keep it from turning(like a jam nut). The hex nut helps tp protect the threads in the balancer. Then you'll have two "studs" sticking out that you can get a pry bar between and rock the crank back and forth. Don't turn it backwards much if you can help it, but you may have to move it just a little to break things loose. You may have to move them into the other two locations to get room for prybar.
Hopefully I just did a lot of typing for nothing and it's not locked-up.
Good luck,
ssmonty

Don't take offense SS...... Trying to turn it by hand is a good idea, I'd try the crank bolt 1st, but making the rig to turn it by hand sounds like a lot of work if a jump will spin the engine over, if the starter won't spin the engine over (locked up) it would be best to pull the heads and hone the cylinders to remove the rust etc...... It's been my experience after breaking it loose even by hand and freeing up the pistons, rusted cylinder walls ruin piston rings in very short order and lead to more costly motor work....ie the cylinder walls will need boring out instead of a hone job....... just my 2 cents

hand crank?

I have a 472 Caddy running my sawmill. 4 ft round blade. I hadn't used it for about 5 years and wouldn't turn over with the battery, or with a wrench. I pulled the plugs, shot in some penetrating oil . after a couple days it still wouldn't turn so I pulled the starter and used a couple pry bars to work the flywheel teeth and got it moving back and forth, Then It fired up no smoke, sounded good, caddys have a high nickel alloy, good engines ,

Another way to turn it over is to pull off the transmission cover and use the flywheel/flex plate to turn over the engine by hand. The flywheel is large diameter, so it provides quite a bit more leverage than you can get at the balancer end of the crankshaft.

You can buy or rent a wrench to fit the teeth of the flywheel; however, with the plugs out I've been able to clamp a set of vice grips on the metal ring on the flywheel and turn it by hand quite easily. I used this method on my SBC 350 the last time I replaced a camshaft and needed to set the valve lash.
