W114 Blowing #4 Fuse

[marken]

I recently purchased a 1972 250C. It will run fine for a somewhat short time but then Fuse #4 blows. Once blown the car won’t idle and stalls when put in gear or reverse. Prior to when the fuse blows the right turn signal works but not the left. After blowing neither turn signal works. Any suggestions on tracking down what may be causing the fuse to blow? Also, the emergency flashers don’t work. As a side note there was a white 8 amp fuse in the space when I got the car. I was told by the previous owner to put in a red 16 amp fuse and give that a try.
