I have no power to the left side of my fuse panel in my 90 Blazer. This portion of the fuse block holds the ECM, Horn/Dimmer, and Tail/CTSY. All of the other sections work fine except for this column. I have also checked the orange wires hat plug into the tops of the fuse panel...the one labled 'battery' at the upper top corner fo the column and the other orange one that is down two below that one that also reads battery. There is no power comming out of that wire..should those be hot leads comming INTO the box or comming OUT of the box??The truck will not start w/o jumping the fuse box to get it power to that side. I used to have a jumper going from the bad side 'pwr' connection right above the shunt to the working side and it starts just fine. I crawl under her and look at the starter wires and there is a fat orange wire that has a fuse link on it...power comes out of it..find the two red wires leading into the firewall..one has power to it..this one is comming from the junction block. Traced the other wire out and it plugs to the alt. This wire has no power going through it (is it suppoesed to?) I jump the non working wire to power and it fires right up..take the jumper off and it dies..SO I plug the jumper back into the fuse block and check the wire again (at this point i have taken the jumper off of the fire wall...the jumper is inside on the fuse box like it has been for the past year)...so after jumping it inside the fuse panel the red wire comming from the alt is hot..I dont understand why this is..if there is something wrong with the fuse panel why can i jump it from inside?? can i just run a hot lead from the junction or battery and splice it into the non-working red wire in the firewall?? sorry if this is confusing or that im asking too many questions but i need help with this in a bad way..im sick and tired of driving my little neon around and looking at the big beast just sitting there in the parking lot. Any help would be GREATLY apprecitated.
