Under the hood drivers side fire wall/fender relay fuse box near front 10amp fuse. what does it do?

 

I needed to find the trailer lights fuse the other day. I don't have a manual so I googled it and found what I needed it has the info you need

 

Here is a link to where u can get the owners manual: https://www.fleet.ford.com/maintenan...ls/default.asp

#20 is the electronic rake controller btw.

 

Thank you so much Capt.

 

According to what I read this is incorrect. The OP is asking about fuse #20 in the power distribution box and the fuse referenced above is in the passenger compartment fuse box.

Fuse #20 in the power distribution box (located under the hood) is a 10A fuse for the trailer back-up lights (reference page 223 of the 2005 owner's manual).

The fuse which powers the trailer brake controller is #20 in the passenger compartment panel and is a 15A fuse (reference page 219 of the 2005 owner's manual).

 

Oops! I thought I was looking at the under hood fuse box. Sorry.

 

The OP did say it was the under the hood fuse box.

 

Thanks for all the great info everyone, got a good handle on the fuse, now witch trailer is wired wrong?

 

Can't help much with that other than to say I would check for a short circuit first. If everything thing was OK and all of sudden you are blowing fuses this is the most likely culprit and easiest to check for.

Good luck.

 

check your light bulbs on the trailer mine was blowing fuses and the bulb was making contact to both th eground and the power lugs

 

Not sure when the fuse blew, I don't use back-up lights on any of my trailers. The last electrical modification I did was replace a worn IV cable, and I will tear it apart and make sure I didn't cross somthing up
