Battery Power - Zero - While Driving

[heyaim]

While driving we lost all power and had to pull over. We were able to get to our destination. We haven't found any wires not making connection.

The battery has been tested - it's good

The Alternator has been tested - it's good

The Regulator has been tested - it's good

I guess the next step is to replace the Isolator?

Any other things we should be checking? Changing?

It's looking like our trip this weekend isn't going to happen. We are on vacation for a week starting the 13th! OMG, I hope it's fixed!!

I realize you have already said there are no bad wire connections, but what you're describing sounds like an open circuit somewhere. Check all of the wire connections, and the wires themselves, very carefully.

I hesitate to even bring this up, but I assume you checked all fuses and circuit breakers?

For people to help, you need to be a little more specific about what you have (ie: ford, gm, etc. chassis) and more detail than "While driving we lost all power and had to pull over". That could mean the engine stopped running or all the house lighting went out. There is a chassis system and a house system in an RV. You give information about chassis but then talk about an isolator. Isolator is a cross-connect between the systems for battery charging of the house battery via the engine alternator however do you have a electronic (diode) or relay based system. Without knowing these things people cannot easily help you. The devil is in the details so to speak.
