Inline fuses
First thread on this forum hope I don't sound to dumb ! The wife and I are about 500 miles from our home in Tennessee and are having an electrical problem with our 2019 3560 Montana. The major problem turned out to be a bad shore power breaker at the campground electrical pedestal which resulted in losing one leg of our 50 amp service. That was fixed quickly by the campground maintenance personnel. The other problem was that during my trouble shooting I discovered a blown inline fuse. At this time I don't know what it goes to and have not found anything yet that doesn't work. The question is what does the 30 amp inline fuse that is powered by the jumper between the 50 (?) amp hydraulic pump circuit breaker and the 30 amp (?) circuit breaker on the wall just forward of the 12 volt batteries ? There appears to be a dead short because before I can get a new 30 amp inline fuse seated in the holder it sparks and blows the fuse out. Thanks in advance for the help !

Hi Ken,
Do not have camper at home to look. But I do have a question. Are you sure it is a 30 AMP Fuse?

Ken,
I am sorry I a fumbling blind here.
One thing to look at is if your propane detector is one
your gauge LEDs light up?
Does the convertor come on if you turn on enough lights?

if it is the converter then all will seem okay until the batteries die

The propane detector is showing a steady green LED which indicates a normal condition. The battery voltage is holding at 13.6 volts which is a normal maintenance value indicating the convertor is working.

Could that be the fuze that protects the system if the batteries or connected improperly?

On our 5wheel the reversed battery fuses are located with the circuit breaker and fuse panel by the steps to the bathroom and bedroom.

Do you have a residential fridge? I have a blade in line fuse between my battery and my inverter.
Good luck
Steve
