I have a 2000 s10 it blew the ignition fuse the 40 Amp under the hood I thought it was the ignition switch replaced it an found it was the fuse then tonight the heater wasn’t blowing so I turned it off an went to restart it and it kept cranking til I disconnected the battery then everytime I put a fuse in it blows I’m thinking the relay is stuck open buy I don’t know what would cause that need input please truck is on the side of the road


93 s10 Tahoe blowing fuse when it happens I lose amp gauge and tranny seams to hold back the fuse is the ignition fuse but stays running starts right back up no problems but I hit a bump and she blows again, also when I touch the brakes it goes into passing gear so I am likely looking for chafed wires ir melted but should I start at the brake lights?any ideas are greatly appreciated thank you

Start by having the engine running and grab a hold of the engine wiring harnesses in different placed and move them around. Try to get the fuse to blow. Then you will narrow down where the wires are shorting out / rubbing.


changed fuel pump,strainer,spider f.i.still won’t crank recently had motor change.


If the motor has been out, you might want to look for something that has been left off, or got accidentally disconnected. Possibly even a smashed wiring harness somewhere that got caught where it shouldn’t be.
