There is a solenoid that connects the coach battery bank to the chassis battery bank when the engine is running and depending on the coach manufacturer when connected to shore power. It is very common for that part to fail which has the effect of no power while driving. If this is the case your coach battery bank is likely shot and will need to be replaced. It is easy to test to see if this part has failed. With the coach running connect a multi-meter to the coach or house battery bank. You should have about 13.6 VDC. If you have less then the relay isn't working.
