Generator not switching and delivering power

Some may remember me,some not. We had a couple life changing events that redirected our lives. Life has a way of kicking you in the nads without any regrets. It has been a four year long bout but we are through it. The sun does shine on the other side.

So without a big story, we decided to sell old blue. I have a buyer that is interested. I pulled it out of the barn to spit shine it. The generator runs fine, it is just not switching and delivering power. I know the gen is making power as I got hit doing something stupid.

It is a Kubota diesel engine with a Wrico generator.

Check the transfer switch

Yep, sounds like a transfer relay to me, but without knowing anything about how your electric is set up, that's about as far as I (or anyone else) will be able to diagnose it.

Is the shore power working ? On our Trek the switching is done by the inverter if the friggn house batteries are dead it will not switch over

make sure you have a automatic transfer too and not a manual switch

I have narrowed a problem to an area. I sent a pic to the buyer as I had already told him the gen worked fine. It did the last time I used it. So in discussions with him I sent him this picture. I sticuck the camera in there and in reviewing the picture I saw the black discolored area. The wires from the PCB leading to the switch for gen power in, got real hot. In the next post I will put up pics. Oh if I open the switches manually the bus gets power.. So the problem is not the breaker box and not the gen. Its isolated to the switches or PCB.

I bet a nickel to a pickle I know what happened. During the morning of the flood the contractors came to the house. One of them wired a 50 amp receptacle in my pump house where we moved the bus too as the water was coming up. The gen was running. I would bet the farm he plugged it in with the gen running.

Luvrbus I am glad your chiming in. It does work off of shore power. April before last we got 4 foot of water in the house. We lived in the bus for a week before moving to Bellville with my sister and bro in law. I vomited to work for 6 months waiting for the house to be rebuilt. I stayed in the bus twice a week. It was plugged in the whole time and worked great.

In the first pic there are 3 switches. The left is gen coming in, the middle is shore coming in. The right is power from the switches to the breaker box. The PCB is to the right of the right side switch. I am,fishing this is the culprit as the wires from it got very hot.

Just a long shot, I suppose, but does the generator have a reset switch?

That looks like a homemade switch assembly. I also made my own after the store bought one started humming. But when I made mine, I hooked it up so if the generator was running, plugging into the shore power wouldn't connect saving my generator.

I'll go look

No reset. When I open the switches and let power from the gen to the bus, I can hear the genset lag as it delivers power. I can hold the switches open but within a minute it stops delivering power. Just to be clear, it's stops providing power while I am manually keeping the switches open.
