Fuse #5 blows when I turn the key to the 2nd position. I have no idea whats causing it.

There must be a bare spot of wires where the +wire touchs a ground.

Wagon or sedan. Auto or manual?

If tomatoes are technically a fruit, is ketchup a smoothie?

It's a manual sedan.

Most likely reason for fuse 5 to blow in an M47 car is the insulation has fallen off of the wiring to the backup light switch. Check the wiring underneath, and maybe disconnect the blue wires from the back of the fuse panel at the fuse 5 terminal to see which one kicks the fuse and leave it disconnected. Then be sure your turn signals still work and maybe you can wait for better weather to replace the wiring to the backup light switch. Sorry, this is a lousy job.

Mechanics are often working with their hands in an area they cannot see, much like cleaning up after #2.

Sorry for the late reply but I was able to stop it from blowing. I was able to disconnect the backup switch wiring. I checked the wiring underneath and found that it was shorted and had a lot of electrical tape around it. Thank you for your help.
