Main 12 volt feed? Pull them and see if all other 12 volt circuits stop working.

The pair of red 40a fuses in the notch on the left side. They are reverse power center battery polarity protection fuses. They protect the convertor from improper battery connection.

the fuse size is chosen to protect the wiring not the component. each component should have its own protection. ie the wire size determines the size of the fuse.

x2. 14AWG= 15AMP 12AWG=20AMP 10AWG=30AMP

Now, this can change if the wire is long, you have a voltage drop requiring more amps.

For example, if you are running 2 100 foot 14 gage extension cords in series, both rated for 15 AMPS, you most likely can not pull a full 15 AMPS from it without it getting warm and/or possibly melting. It may not trip the breaker as the extension cord now becomes the weakest link and acts like a fuse by excessive heat and melting. Please do not try this experiment at home!

Check out Ohm's law - Wikipedia, the free encyclopedia , Electric power - Wikipedia, the free encyclopedia , and American wire gauge - Wikipedia, the free encyclopedia .

The only things I know about electrics and electricity I learned wrenching British sports cars in the 60s and 70s.

Lucas electrics worked because of the mystic smoke inside, and when that leaked out of a component, the component stopped working.

Update!!

UPDATE!!

I got another phone call from Tony Hufnagle at Forest River this morning. He wanted to check that he had told me about the "other fuse"... which he hadn't.

It seems that the AM/FM radio gets its power from the circuit protected by the 15A "ST" fuse but that fuse is not intended to protect the radio. There is a separate 5A in-line fuse in the power lead behind the radio that does that. It is accessed by removing the radio from the cabinet (a screw in each corner, may be behind surface plugs).

He indicated that the 15A circuit could carry televisions, CD/DVD players/recorders in the same cabinet or that other electric components elsewhere in the trailer may be fed by the "ST" circuit.

Whodathinkit?
