Hiu. I have a 96 Blazer. I have a weird problem with it. It is cold here, but I don't really know if it matters or not. I can go to start it, and turn the key, and nothing. I have a new battery in it. There is still alot of power in it. The dome light shines bright. I can wait a while, and it starts right up. I went to the shop. They went over it, and said it is clear. They kept it for 2 days and never had a problem with it. I thought maybe a neutral safety switch, but found out that there isn't one. I am thinkinging now of something where there might be points somewhere that are sticking.. I just put in a new Interstate battery about a month ago. I did notice that when i installed the battery that after I put the cable on the positive. I put the cable on the negitive and it sparked. Something is drawing power. They only thing that I installed on it is a new radio, but it was a optionoem for the 96. It was just a plug and play. The draw would be the memory. The only other thing is a trailor conection. They checked that out and it looked fine.. Any idea as what the heck this could be?? Oh, and when you turn the key and nothing happens.. I put on the battery charger, and it will start right up.. Al
