Ihave a 99 NBS GMC Sierra. I went to start it last night and everything seemed to short out and drain the battery. I let it sit for a minute and the lights inside came back on like normal. Now i can put the key in and turn one click and all the dash lights will come on just fine. Here is the problem. if i turn the key 2 clicks to the ON position, everything goes black like the battery was disconected. I can also here a quiet continuous clicking coming from under the hood. I tried reseting the battery as well as jumping the battery. It seems as if the battery is fine but something is wrong with the starter or ignition. Or maybe some sort of short somewhere? If anyone has any ideas, please let me know. Thanks

 

If it is clicking or turning over the starter should be fine. I had a problem like that once with my old car. I would check the alternator. You can take it to a local auto zone or something and they can check it for you.

 

It will not try to turn over. The clicking is very quiet, not like a dead battery click. I will get it towed to a shop but was hoping i could fix it where it sits. thanks for the help.
