Mechanical Problem with a 1997 GMC Jimmy need help ASAP?

[Jay_in_302]

I've been having a problem with my 1997 GMC Jimmy Truck for the past month and a half. I'm by no means a skilled mechanic so that's why I'm posting this. I go to start it in the morning and it won't start. Now I know what you are all thinking, (its the battery jackass),but acutally I've replaced the battery 3 times (walmart is getting sick of seeing me). I've replaced the battery cables because I noticed that the negative wire that was connected to the battery was loose but still problem not solved. Just a couple days ago I bought a new started thinking that it was not getting good current from the battery....but I went to try it today and still not starting. I'm sick of getting jumped every morning which is when the problem occurs. When I do get jumped the entire day the truck starts as normal. I'm tearing out my hair over here and would like some help if anyone knows how to fix this problem. One last thing I can think of is to ground the radio because my ground keeps coming out the back of my radio when I place it back in. Thanks and hope to get some answers this shit is lame hahha
I don't know if it matters but I had autozone check the alternator they said it was fine can it still be bad if its been tested????

Unfortunalty you have a short in your electrical system, and that is one of the hardest thing to locate and given the age of your Jimmy. It could be anywhere, Try with the simple things like check to see if the light and hardware under the hood for the engine compartment is corroded which could be causing the short, or the way the radio was wired up since it's an aftermarket. Look for any of the power wires that may have gone loose and shorting out causing the current drain.

If you have a multimeter, you can try checking all the fuse holders and see which on is still pulling a current draw with the ignition switch off. Good luck and keep us all posted and the other common place that I found is the over head vanity light on the visor if something is placed between there and the light stays on pulling current from the battery, leaving it drained.
