Radar22 Posted December 27, 2021 Share Posted December 27, 2021 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 Link to comment Share on other sites More sharing options...
vito.a Posted December 27, 2021 Share Posted December 27, 2021 Are you plugged into shore power or running the generator? Link to comment Share on other sites More sharing options...
Jim Byrd Posted December 28, 2021 Share Posted December 28, 2021 Not unusual if you have second charging source connected to the chassis batteries when you engine is running, Jim Link to comment Share on other sites More sharing options...
redstickbill Posted December 28, 2021 Share Posted December 28, 2021 I had the light come on after an alternator repair, problem was a 5 amp fuse in the wiring close to the alternator. Bill B (that problem was with a 2004 Endeavor) Link to comment Share on other sites More sharing options...
Larry Maida Posted December 28, 2021 Share Posted December 28, 2021 Quote My light will blink if batteries are fully charged and alternator is pushing 13.5 or 14 amps. I turn on my marker lights and it stops blinking. If I leave markers on for about an hour it is corrected. Link to comment Share on other sites More sharing options...
Michael Powell Posted December 28, 2021 Share Posted December 28, 2021 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. Link to comment Share on other sites More sharing options...

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. 19 hours ago, Larry Maida said: 7 hours ago, Michael Powell said: If you turn tour headlights on and it goes off.

Steven P Posted December 31, 2021 Share Posted December 31, 2021 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.

Busnut Posted December 31, 2021 Share Posted December 31, 2021 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. Link to comment Share on other sites More sharing options...

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. 1 Link to comment Share on other sites More sharing options...
