My dad's 1997 Dodge Ram keeps blowing the 10 amp mini "engine" fuse that is in the fuse block in the cab. It did it once about 2 months ago. I figured it was just old being a 13 year old fuse. It just turned off like I shut the key off. It took a bit of searching to find the fuse had blown. It had no spark and no fuel pump, being as how the fuse controls this.
It ran fine for 2 months then yesterday it blew it. He replaced it and it ran for about 30 mins then it kept blowing it everytime he would turn the key on, whether just turning it to on or trying to start it. He tried 15 amp, 20 amp, and 30 amp and they all blew. We had to get it towed home. After it sat for awhile he replaced the fuse again and now it's running fine, not blowing the fuse but he's scared to drive it, save having to get it towed again. From what I've read this fuse controls the injectors, fuel pump, ignition coil, and heated o2 sensors, (and I think egr but it doesn't have one). Any ideas on why this fuse would blow? And why this pattern?
I NEVER get problems like a bad alternator or blown rad. I ALWAYS get problems that are IMPOSSIBLE to trace and have no rhyme or reason.
