NO 12 VOLT POWER
LAST NIGHT WE RETURNED FROM A TRIP AND PARKED THE COACH, it was not hooked up to shore power. I TURNED OFF THE SWITCHES IN THE BATHROOM BEHIND THE COMMODE. That included the 12V Heat, 120 v heat, 12 v water pump, and anything else that would draw power overnight. This morning I started up the coach to put it into the garage, and I have no interior lights and nothing at the switch pads. I looked at all the breakers in the bath behind the commode and the breaker boxes in the 2nd bay drivers side. Nothing was tripped. I checked the inverters and they appear to be fine. I also don’t have the light at the entrance door that comes on when you open the door.
I don’t know what else to check. Everything was working fine when I shut it down last night. This is a 2006 H-3 converter Marathon. Anyone got any ideas what else to check?

You need to say who the converter is for your bus. That way someone who is familiar with that conversion may be able to help you. As it is, nobody will have any idea what you are describing or where exactly you are looking at something.

Thanks Mark. It’s not a mass converter. It is Superior here in Nashville and they build specialty and mostly tour buses. Each is a little different so I was hoping for more general “check here this or that” guidance. It may not be possible. Thanks.

Paul check the input and output of each compoenet from the battery to the end device. One of them is not letting power to pass thru. A 12 volt light probe would be a quick way. Just ground the ground wire and start poking connectors looking for light or no light.

Without the diagrams your only way to find the open circuit is to start at the batteries and follow the flow of current until you find where it stops. It is so easy for me to say that, not so easy for you to find it.

Make sure the solenoid is passing power. The last thing changed is always the first thing to check when a new problem pops up. It is possible that you pullled a fuze that applies the power to engage the solenoid. You may have to hit the switch that controls the solenoid and turn it back on.
Or, one or more of the fuzes you pulled did not get reseated all the way?

Do you have a separate 12V disconnect

1st thing check the salesman switch at the entrance door to see if it is on, that switch turns on a silver solenoid that supplies most all the DC power to coach,Mine is in the DC power compartment, with the house batteries, they do burn out, This is not the Solenoid but it looks a lot like this, It has to be 100 plus amp and 100 percent duty cycle, meaning it has to be on most of the time. The big bolts go between the positive cable on house batteries and small screws go to salesman switch
