76 chevy battery drain


Recommended Posts

Hello,

I obtained a 76 scottsdale chevy so I could drive it to work, it seems to run very good but if I leave it sit for the weekend and sometimes any random day, it won't start. It seems like the voltage gets down around 11. I did a parasitic draw test and it only shows .002 Amps being drawn. Is this possible? The truck has almost nothing that could be using power. A lot of the accesories fuses are gone and other things disconnected. No interior lights work.

Any ideas would be appreciated.

 

I tried to jump it today when it wouldn't start and I got nothing even though the voltage read around 12 inside the truck, and that gage is accurate. Maybe I just flooded it, I don't know. Had to take my girls car to work.

 

The alternator always kept the battery charged as long as I kept starting the truck. When running the voltage goes up to 13+v

Does gas leak out on to the ground if you flood it too much? I think i have a puddle under the truck but I can't imagine it flooding THAT much.

generally you need to give it a good rev to get it to start

I assume you mean a puddle under the engine? If yes, then you probably have a leak somewhere more than just "flooding" the carb. I've flooded a good many engine in my day but never had a puddle.

Apparently it's transmission fluid, not worried about that right now though.

 

It seems the truck has trouble starting in the morning when it's a little cold but in the afternoon it starts right up. Even though it doesn't get that cold here right now, I'm in South GA.

 

Also in the morning the voltage on the dash seems to be right on the line in between 8v and 13v so that would be 10.5v. The battery read with a multimeter reads over 12.6v.

Once I get it running and after I shut it down it keeps a 13v reading on the dash. It took me several cranks to get it started seems to almost weaken the battery.

 

Does this truck need a choke? I believe there is a knob for it inside the truck but it's pulled out all the way and when you push it in it just springs back out. I don't believe it is even functional, I can't figure out where the cable goes, nothing comes out into the engine bay from there.

Yes it needs a choke and it has to be adjusted so it can work properly . It should have an automatic choke unless someone changed it over to a manual choke. And if the choke is adjust properly. And there is nothing wrong with the carb then when you first start it up you push the gas pedal all the way to the floor to set the choke. And if it is a manual choke then you push the gas all the way to the floor and hold it there while you pull on the choke cable to set the choke. ( You don't crank it over while you are doing this procedure) Once you have done that then release the pedal. If the chokes are adjusted and there is nothing wrong with the carb then it should start right up. If it don't then you need some work done.

I pulled the spark plugs and some of them came out with some kind of insert still screwed on to them (rusted), and these inserts cover up the electrode, I've never seen these before what exactly are they for? I would think it's an adapter for maybe fixed threads in the head but then why does it cover the end of the plug with only a small hole in it?

I've put together a 350 before and they didn't have these inserts in the heads like this..
