Ground Problems

[Japsrks]

I replace the solenoid, alternator, igniton switch and key switch , trying to locate where I am getting fire into my negitive post on battery, only thing I have left is starter, why is it that I am getting fire into my ground?

im a little slow can you re-frase that for me?

I am sorry, I don't know what you mean by "fire into my ground" I am going to guess that this is what is happening. If I am right or wrong please let me, and everyone else know, and then I am sure more help will be forthcoming.

I guess that when you pull your negative cable from the battery, and when you go to reattach it, that you get a spark.

IF I am correct.. is it a big spark? or a small spark?

The greater the drain on the battery, the larger the spark would be.

You could have a small drain on the battery for things like an under the hood light, perhaps your clock or radio.

If you have none of those things, or the drain is more significant then you must have a short somewhere, or a number of slight shorts, none of which are strong enough to blow a fuse.

Perhaps you have a 30 amp fuse where there should be only a 10 amp fuse.

To try to narrow down the system that is causing the drain, assuming it is a problem, and not just the under hood light, you may want to pull all of your fuses, and check to see if you still ahve a spark at the negative poll of the battery, and if not, then replace your fuses one at a time and check the negative poll. IF and when your spark returns, then you have narrowed down the circuit that the short or drain is from.

Does this sound reasonable?

when I connect the neg post of the battery cables it sparks, an the starter trys to turn over without the key switch on or the key in the truck. I had the starter tested an Auto Zone , they tells me the starter is fine,

Your starter can only try to start if there is a complete connection of both positive and negative. Disconnect the lead from the solenoid to the starter. I'm expecting that it will no longer try to turn over. If that is the case, then you have a stuck solenoid, or a hot lead going to the solenoid coil. Get a volt meter and check the solenoid connections. You should have 12V on the lead coming from the battery. With the key in the OFF position, then you should have nothing on the other terminals. If you have 12V on the small lead going to the small post on the solenoid, then you have a problem in the pick circuit, most likely at the key switch. If the small terminal doesn't have 12V on it, and you have 12V on the large terminal going to the starter, then you have a stuck solenoid. In the above, I'm assuming that you have the connections on the solenoid correct. Post a picture of the solenoid showing the connections.

Good luck,
