New to me, only one hunting trip last year so far, but didn't have the gen running at all then. Shore power works normally. I assume it has a transfer switch (somewhere), since the output seems hardwired, with no receptacles on the gen. It's an Onan marquis 5000. The breakers on it don't change the situation, on or off. The fuses on the gen are ok. Scratching head...lolIs this coach new to you, or have you had it for a while and the problem just popped up? Does everything work when plugged in to shore power? Does this coach have a transfer switch, or does it have an outlet that you have to plug the shore cord into to get power from the generator?
Maybe check the two breakers on the generator itself.
I wouldn't assume a transfer switch in a 1994 rig.I assume it has a transfer switch (somewhere), since the output seems hardwired, with no receptacles on the gen. It's an Onan marquis 5000.
Look in the compartment where the power cord is stored for travel. It is very common or was, to have that in place of an auto transfer device. If there is an auto-transfer you can find it by following the shore power cord to the other end as that would be located between the generator & power cord with the output going to the 120V distribution panel.But I would look at each that are next to genny, usually outlet mounted on a wall.
