Not unusual if you have second charging source connected to the chassis batteries when you engine is running,

Does anybody know why this light comes on the dash. Just had coached checked for alternator issues and possibly a  parasitic draw. All checked out Ok. thanks 

That light is driven off one AC trail on the generator.  If the voltage there subtracted from the chassis battery voltage, is not greater than 6 Volts, the light will come on.  If it is intermittent, then it's not likely a fuse.  First, check your chassis battery voltage.  It should be 14.2 - 14.4 Volts.  If not, check right at the alternator.  Check for good grounds.  Lastly, it could be the 6-volt ALT-FAIL Relay.  It's the only 6-volt relay in the coach.

If you turn tour headlights on and it goes off. There is a kit that uses a relay that fixes that... I haven't done mine yet because when it happens I just turn on the headlights fir a while then turn them off all good 2004 Monaco Dynasty.

As others said above, mine will do that if I have the generator running and then crank the engine.  If I have the engine running and then crank the genny it doesn't do it so I try to stick to that method.  Turning on headlights or parking lights makes it go away.

I had the light come on after an alternator repair. I changed out the relay for the ALT light. I didn't have any luck with that. I changed out the circuit barker in the rear panel. That fixed the problem.

Which breaker was it?

Turning on the lights is a dead giveaway... I talked to a tech at monaco in 2015 he sent me a fix for that will look for it thus coming week.

Any way I could ask you to post a pic of it on your coach?  My drivers rear bay is 110v only.
