i was trying to start my 2001 blazer. it turned over a few times and i had no power, no dash lights, no radio, no interiot lights, I couldn't even lock my rear door. i disconnected my battery let it set, reconnected it nothing....i let it set over night...nothing.. i looked at my key and it seemed a little bent...is there a anit theft or something of that nature that needs reset??
before all this happend i was having a hard time starting in the morningn when it was cold..i would have to prime the engine....i think that is the cap and rotor needing relaced..i have lots of miles...and havent done so....the only power that i do have is to the 12v accessory plugins inside the vehicle....

 

You are going to have to go through things with a test light. If you do not have power to anything inside, then there is a problem either with the battery, with the master bus fuse, or the fusible link (positive battery cable).

 

i did some checking and i found a 30a fuse along with a 10a fuse in a fuseblock which is alongside the battery in the fender. the 30a is blown and i am going to checkers to get another. The 10a is good. hopefully this is the problem

 

isnt checkers a Fast Food Joint???

 

I have no idea what the 30a fuse went to but i replaced it and nothing.....
i towed the blazer home....i started checking with a 12v testing light and no power any where, except at the battery.....checkd the battery cable and no juice from the battery to the battery fuse block 175a.....replaced cable using afro engineering not buying oem replacement cable $105.00 everything good to go blazer staarted and am cruising...
i still dont know what that 30a fuse went to it was in a fuse block with a 10a fuse and a relay in the passenger side fender????
anybody know?????

 

it should say on the cove or the fuse block what fuse it goes to according to the spot that it was in. and you will also wan to check your ground wire. my buddy just went through having a bad ground on his 94 blazer. and also check connections to the altenator.
