Hello, my '93 ranger's instrument cluster fuse (#7) will blow at the most random times. I have had it blow as i pull out of the driveway, as i'm going down the street, and even while i was just sitting in a waffle house parking lot listening to the radio. Has this been a common problem with older rangers? Can anyone tell me where to start to find the problem?

 

Ok, well I got a new oil sensor from the part shop and went under to change it. Got the damn thing 98% off and realized I would have to take the starter out to replace it. I also noticed the threads from the one on the truck and the one from the shop were different. So I said to hell with it.

A week or so later I went under to check if the wire was maybe chafed or something. found another sensor in the front of the oil pan that was rusty and lookin like ****, turns out I was looking at the wrong sensor the whole damn time.
