Hello everyone was just looking around the engine bay on my 06 commander 3.7. And I seen a random fuse holder connected from the positive to negative battery cable and runs back behind the motor. There is no fuse is in. It reads PA66 FUSE. Can anyone help me out here and tell me what it is. I'm having no issues just don't know what it is or for
Thanks!

I did a search of the Service manual for PA66 and didn't find anything. Might be an aftermarket thing.

Humm it's weird I popped open the cap and there wasn't a fuse. It definitely looks factory or OEM with having the cable protection in it. I guess I'll do some more research

Yeah here it is. There is a white wire to the negative and a red to the positive and then runs behind the motor

I was thinking if you posted a pic of it's location in the engine bay someone might be able to help you out. Sorry, but I haven't got a clue.

Ok thanks. It was just dangling near the driver side fender under the hood. It looked like it was secured to the fender at some point but can't really tell where

A random educated guess would be it's the fuse for your trailer light wiring harness.

If it is, your trailer lights won't work until you put a fuse in it - a lot of people remove the fuse when they are not actually towing a trailer.

You do have a trailer hitch correct?

If so, that's most likely what it is.

Yeah I do have one but have not used it yet. I'll keep that in mind when I go to tow my bike to a buddy's house this weekend. Could you guess what amp fuse it would use?

A 10 amp fuse is pretty standard for a trailer light wiring harness, you could use a 20 amp fuse if that was all you had - but a 10 amp fuse is more than enough.
