Generator auto start

I have a 2000 Winnibago, Itaski Horrizon with a 7.5 Onan diesel generator. While parked at my home I have gone outside in the morning and found the generator running 3 times. Neither my wife or myself started it during the night and the coach was locked up. Does anyone have an intelligent idea how this could happen? Thanks

Does it have a low battery sensor? Some MH have this when the voltage in the batteries drop below a certain level the gen. Will start automatically.

Your batteries have went down and your automatic gen start kicked in to charge them. You can disable it but its doing it job.

1. If it is equipped with an auto start system (mentioned above), it may start up by itself if the batteries get too low OR the A/C thermostat is calling for cooling.

2. If you do not have auto start, there is a known problem with these sometimes starting by themselves.

You will have auto-start controls on the remote panel if you have Auto Gen Start. Often the panel is labeled AGS or similar. It may also be part of the inverter remote panel, if you have one.

If you do not have the AGS feature for your genset, you probably have moisture in the generator start switches or wiring harness. This can short the contacts and cause the genset to initiate start-up. A hair dryer will thoroughly dry out each remote switch. If that doesn't do it, you may have to dry out or repalce the wiring harness to the genset, or maybe even replace the genset's remote interface module.

If you don't have AGS system then look on the top of your generator for animal (cat) foot prints in the dust/dirt. There's been more then one case of people on the forum finding their AGS problems were varmint related.

If you do have the AGS system, you can set several parameters. including how low the battery before it comes on, quite time so it does not come on during a certain nightime hours. As was mentioned, it's doing it's job if you have this. Many people wish they had it just because it saves your battery.
