Cyclone 3800HD Switching Issues

[ZeroFoxSpecialized]

We have just bought a new to us 2012 3800HD and the generator fires up and runs,but will not power anything inside the coach. I have heard about a switch that is suppose to kick in when the genset fire us. Can anybody point me in the right direction on where to find it and is it something a reasonbly mechanically inclined person can swap out or a RV Tech might be a better idea.

Thank you In Advance

You need to find the transfer switch, you can trace the largest cable coming out of the breaker box to the transfer switch. You will have 3 cables going into it.

Check the generator breakers before digging into the transfer switch

As LBR mentioned, if the generator is a 5500, there should be 2 breakers on the front near the start switch. One breaker would be a 30 amp, the other breaker would be a 20 amp. Make sure these are working. But to answer your question the transfer switch should be behind the basement wall. It will have as said, 3 cables, one from your shore power, one from the generator and the output to the breaker box. MAKE SURE you disconnect ALL power before you open it up and start on it.
On our Road Warrior the generator is the primary supply. If the transfer switch senses power from the generator, it switches to the generator. We had the transfer switch start acting up on us in January 2020 and I had to replace it.

I think it would be a useful addition to have LED pilot lights on the outlet of each phase of the generator, and maybe on the incoming power connections to the main circuit breaker box.

Maybe something like this: https://www.ebay.com/itm/284786177010?hash=item424e9433f2:g:Ke8AAOSw7k1iZ3aa

Well it turned out be a combination of issues. The circuit breakers at the front of the genset were weak and also the switch had some rodent damage. Quick run to Cummins got 2 new breakers and some quality time with wire strippers and connectors and shrink tube got that issue fixed. Also picked up a new fuel pump and filter and gonna service the rest of it.
Thank you all for your help and input..

Good for you, glad you can get it running. Which switch had the rodent damage?
