SOLVED: Ignition Fuse keeps blowing

Detail: My 04 Tahoe keeps blowing 10A ignition fuses. If I put a new fuse in it, it will last for a day or so then it wont start again. It seems as though when I drive it around and then try and start it again it blows. I can turn it on and off in park 100 times and it wont blow. Seems like a loose wire but there’s so many I don’t know where to start. I've even put a 30A in there and eventually that blows as well. I know there was an after market alarm system put in but it was disconnected by the previous owner. My mechanic checked the starter and the connections but cannot figure out why this is happening. Can somebody please help me?
Detail Question SOLVED: Ignition Fuse keeps blowing

Solution: Hi Jeff , in what fuse box is this 10 amp ign. fuse located ? I am looking at a power distribution diagram and i see a IGN 3 10amp fuse located in the I/P fuse box ! Is this the fuse that blows ? I see where you replaced the 10 amp with a 30amp . That is never a good idea , you don't want to make your problems worst . Melt wiring harness , could start a fire . Do you know how to do electrical trouble shooting ? How to use a wiring diagram , power distribuition diagram ? That fuse is hot in the run , powers the rear Heat / A/C , automatic level relay, ESC - electronic suspension control module , rear wheel steering control module , Plus someother thing's depending which vehicle , Y91 - ULT . Your Taho doesn't have all this options . , Hi, A 6ya expert can help you resolve that issue over the phone in a minute or two.

Good luck! , HI... ON the fuse box cover. IS there a especification for the funtion of the fuse. or the number of the location of the fuse. If you can give me, I can try help you. as more I can. Thank you for use fixya. , The earlier "fix" suggests a possible wiring problem - more specifically, a historic issue with Chrysler products is the ground connections, which are typically insufficient. Check both the battery to engine and then the engine to frame (firewall). If either are worn or frayed replace them. Even if it looks fine I would still replace the motor to frame cable with a heavy duty grounding strap available at most parts stores. ( doesn't have to be a specific cable - can even be homemade, just make sure it is heavier than the original and is connected to a good, bare area.) , I'm curious, does this vehicle have an alarm/remote starter? If so I expect the installer didn't wire it correctly ... it was an all too frequent issue, with inexperienced installers we had .... I would first suspect any add-on device first (if any) ... In answer to your question ... I know it does have a relay (Starter solenoid is a relay and built onto the starter) As far as it being a relay or the IGN switch ... I'm skeptical. , It is possible that the starer is pulling too much amperage- 1st thing you need to do is find out what if any other consumers are on that circuit, 2nd you need to find out how much amperage is being consumed by the starter. 3rd test you wires most likely if a wire problem it is the heavy hot wire on the starter or the back of the alternator has a loose retaining nut , I had a prolem like this one time a while back. what i did was got the wiring diagram and checked everything that was running through that 30 amp fuse. on the one i was working on it ended up being an injector wire pinched under the valve cover and it didnt short out till the car was driven til it warmed up and expanded after the valve cover gasket was changed. hope this helps!
