When I get into my coach, both starter batteries are fully charged, as is the house battery. However, starter batteries aren't powering anything, including engine starter.

I can start the engine off of the house battery, and then all electronic devices work fine, presumably running off of the alternator.

If I drive for say, 10 minutes, and then turn off the engine, I now have power from starter batteries to devices such as headlights, aux fuel pump, etc with the engine not running. Then, if I try to start engine off starter batteries, the starter briefly tries to turn over then dies, and I lose all power to all devices.

Is there a fuse gone wrong from the starter batteries to the coach? If so, why would devices work after 10 minutes of engine operation?

Any feedback is gratefully appreciated... Thank You!
