I recently bought a 1999 trailblazer project. It has absolutely no electrical power to anything, no indicator lights, no headlights, no electric start. there is a box beside the battery that a red wire from the battery goes to, and screws to the top screw, and then another red wire screwed to a bottom screw in the box and goes to im guessing the starter. If I hook up a battery charger/jump starter and hook the negative to the battery, and touch the positive to the bottom screw on the box it turns over. I doesn't start, but that's because it has low compression so im planning on a top end rebuild, but that's another story. I just want to get the electric start working first, any help would be greatly appreciated. Thanks!

 

Look on up further from the battery and you will see a sealed plastic pouch. This is the main 20 amp circuit breaker that allows power to the lights,switch,etc. They were bad about corrosion/shorting out. Just slice the pouch open and check it out if there isn't power on both sides of the red wire leading in and out of it.If the breaker is bad most auto stores have em.
